QUALITY FURNITURE
When choosing (accepting) goods, be careful about the size, style and other similar qualities of furniture, since the right to exchange goods of good quality, provided for in Art. 25 of the Law of the Russian Federation "On Protection of Consumer Rights" of 07.02.92 2300-1, in accordance with Decree of the Government of the Russian Federation of 19.01.98 No. 55 does not apply to furniture.
The customer (buyer) gets acquainted with the manufacturer's warranty obligations and rules for the operation of furniture. The contract is subject to preservation during the warranty period and is provided to the Contractor (seller) upon presentation of claims about non-compliance of the goods with the terms of the contract.
GENERAL CONDITIONS FOR USE (STORAGE) AND CARE
The period during which the furniture retains its beauty and serviceability depends significantly on the conditions of its operation. Each piece of furniture is designed for a specific purpose of use, so you should use any piece of furniture in accordance with its functional purpose.
Keeping some simple practical advice, You will be able to keep all the elements of your furniture in the best possible condition. Before using the product, the Customer (buyer) is obliged to carefully read the furniture care instructions. Violation of the rules for the operation of furniture deprives the Customer (buyer) of the right to warranty service.
Climatic characteristics and environmental conditions. It is very important to understand how climate and environmental conditions can affect the appearance and quality of furniture. Since furniture products are sensitive to light, humidity, heat and cold, it is recommended to avoid prolonged exposure to one or more of these factors.
Light. Avoid direct exposure sun rays for furniture products. Prolonged direct exposure to light in some areas may cause their chromatic characteristics to decrease compared to other areas that were less exposed to radiation. In case of replacement and/or addition of components at different points in time, there may be a color difference between the elements that make up the furniture. This difference, which will become less noticeable over time, is completely natural and therefore cannot be considered a sign of a low quality furniture product.
Temperature. High heat or cold values, as well as sudden changes in temperature, can seriously damage a piece of furniture or parts of it. Furniture products must be located at a distance of at least 1 m from heat sources. The recommended air temperature during storage and (or) operation is from +2C to +25C. Avoid hot objects (irons, dishes with boiling water, etc.) or prolonged exposure to heat-producing radiation (light from powerful lamps, unshielded microwave emitters, etc.) on furniture products.
Humidity. The recommended relative humidity for the location of the furniture item is 60%-70%. Do not maintain extreme humidity conditions in the room for a long time. Over time, such conditions can affect the integrity of furniture products or their elements. Always keep the furniture surface dry. Surfaces of furniture parts should be wiped dry soft cloth(flanel, cloth, plush, calico). Maintenance of work surfaces (countertops, sinks, etc.) should generally be carried out with a soft, damp cloth, foam sponge or special brushes, possibly using appropriate detergents. It is recommended to clean any part of the furniture as soon as possible after it gets dirty. If you leave the dirt for a while, the risk of streaks, stains and damage to furniture products and their parts increases markedly. In the case of persistent contamination, it is recommended to use special cleaners, which are currently available in a fairly wide range and, in addition to proper cleaning qualities, have polishing, protective, and flavoring properties. In this case, it is necessary to follow the instructions of the cleaners manufacturers on the procedure and area (for which surfaces and materials they are intended) for their use. With absence special means care (cleaning) is also allowed using a small amount of an aqueous solution of a neutral detergent (for example, 2% - detergent, 98% - water). Upon completion of any cleaning, immediately dry (wipe dry) all parts that have been wet cleaned. It is recommended to draw Special attention on internal and poorly ventilated parts, on ends and on connection points. Remember not to use cloths, sponges or gloves impregnated with products that should not come into contact with the materials to be cleaned.
Aggressive media and abrasive materials. In no case do not allow furniture products to be exposed to aggressive liquids (acids, alkalis, oils, solvents, etc.), products containing such liquids or their vapors. Such substances and compounds are chemically active - a reaction with them will lead to negative consequences for your property or even health.
FEATURES OF OPERATION AND CARE
Furniture for sitting and lying. Chairs, stools, beds, banquettes, sofas, benches, etc., are functionally intended only for sitting and lying down. To avoid accidents and damage to furniture, do not allow children to jump on the bed or swing on chairs and armchairs (excluding rocking chairs). Furniture for lying - a bed - consists of a functional part designed to influence the load during operation - a mattress pad with legs, a mattress - as well as a decorative part that is not a supporting element - a drawer, a footboard and a headboard. You should not use the elements of the decorative part of the bed as a support (lean on them, sit on them). It is recommended to place the bed in such a way that the back of the headboard is located close to the wall or other flat vertical support. It is not recommended to stand with your feet on the bed, jump on the bed. Do not rub or hit furniture surfaces with sharp (cutting) or heavy hard objects. If your furniture has removable covers, use the services of special dry cleaners to remove dirt.
Remember: there is not a single type of upholstery fabric, a removable cover that can be washed. Therefore, in this furniture, the use of water to eliminate pollution should be limited. To remove dust and keep your furniture in good condition, the fabric can be vacuumed. Dust can also be successfully removed with a cloth, sponge or soft brush.
Features of the operation of cabinet furniture. Cabinet furniture (cabinets, shelving, hallways, kitchens, tables, cabinets, etc.) should be used in accordance with the functional purpose of each individual item. All weights should be placed inside the cabinets in such a way as to achieve an even distribution of the load over the entire available area and to ensure the necessary balance of the sliding parts. It is recommended to place things on the shelves according to the principle: the heaviest ones are closer to the edges (supports), the lighter ones are closer to the center. Higher elements (columns, stacked cabinets, etc.) are recommended to be loaded more in the lower sections to ensure better stability of these elements. During the operation of cabinet furniture, static vertical load is not allowed. Especially with the application of force to one point: on the bottom of boxes (half-drawers) - more than 5 daN *, on shelves (cabinets, racks) - more than 10 daN *. Normal door opening force - up to 3 daN*, pull-out force for drawers (half-drawers) - up to 5 daN*. Note: * - a load (force) of 1 daN corresponds approximately to the effect of a weight of 1 kg. Do not rub or hit furniture surfaces with sharp (cutting) or heavy hard objects. Please note that the elements of kitchen sets located near gas or electric stove, are subject to increased thermal stress, which is why it is recommended to separate them from heat sources with suitable thermal insulation materials. Please note that only special "built-in" household appliances can be installed in furniture products. Such equipment is carried out by manufacturers in accordance with specific standards and technical conditions (electrical safety, moisture removal, heat exchange, ventilation, etc.) and, as a rule, is somewhat more expensive than "non-embedded" analogues. Remember: under no circumstances should you use the usual household appliances as a built-in, it can pose a real danger to the life or health of people and (or) the safety of property!
Products from artificial stone. The surface of artificial stone is quite easy to restore, but there are maintenance rules that must be followed. Do not expose the surface to caustic substances such as paint remover, turpentine, thinner, nail polish remover, or oven and kitchen drain cleaners. Always use a rack for hot items (pans, pots and electric heaters). Always use a cutting board instead of cutting directly on working surface. Material dark colors not recommended for products such as kitchen countertops, bar counters of restaurants and bars, and other objects with high level loads, as they show signs of wear and scratches. Dark materials require more maintenance to keep their original look. On high-gloss countertops, place flannel or another soft cloth under all items that are placed on the countertop. Never stand on a table top. Avoid sliding objects on a glossy surface. To keep your sink bright and fresh, clean it periodically with liquid bleach and water. Fill the sink ¼ full with water, add bleach, and wipe the rest of the empty part with this mixture and leave it all for 15 minutes. Then rinse the sink. Wipe the inside of the sink regularly with a sponge. Always open cold water before pouring boiling water into the artificial stone sink.
MDF facade covered with PVC film. Furniture facades must be operated in dry and warm rooms not subject to temperature fluctuations, having heating and ventilation at air temperature air not lower than +10°С and not higher than +30 °С with relative humidity of 45-60% (GOST 16371-93). Significant deviations from these modes leads to a significant deterioration in the consumer qualities of furniture. It is not recommended to install heating devices (stoves, stoves, ovens, lighting elements, etc.) near the facades, because contact with surfaces or air with a temperature exceeding 60 ° C can lead to deformation and peeling of the PVC film from the base.
FEATURES OF CARE FOR CASE FURNITURE
When caring for decorative and working coatings, products should be used that correspond to the nature of the coating material. We bring to your attention some examples.
Laminate surfaces. Apart from general conditions care (see above), it is possible to use polishes for plastics. At the same time, for polishing (treatment) of kitchen furniture, polishes (other products household chemicals), which have contraindications for contact with food - carefully read the instructions! Avoid application solid fixtures(scrapers, sponges with a working coating of plastic or metal fiber material) when cleaning.
Details of furniture made of rattan, bamboo. Remove dust from wicker parts of furniture with a vacuum cleaner and clean with a damp cloth. Limit the influence of direct sunlight and heat near heating sources (changes in color shades and binding density).
glass surfaces. It is recommended to clean the glass with special compositions applied to a soft cloth. For cleaning, use special glass cleaners. Do not use abrasive products or scouring pads coated with metal fiber or flaking material when cleaning. It is not allowed to use soda, washing powders, abrasive pastes, powders and other preparations not intended for the care of furniture products. Remember, glass surfaces are brittle and can break if hit. Do not scratch or strike surfaces with heavy, hard objects. Do not subject glass shelves to heavy vertical loads.
Mirror surfaces. Do not wash with conventional synthetic window cleaners. From them, the mirrors can become stained and cloudy. Dry cleaning is also undesirable. After it, scratches may remain on the surface. Mirrors are best cleaned with ammonia or a special mirror cleaner.
Glossy, acrylic surfaces. Under no circumstances should any caustic or abrasive cleaners be used on them, as this could damage the brilliant luster of the surface. Under no circumstances should alcoholic beverages be used. detergents. It is also not necessary to use waxes and polishes intended for furniture, as they contain solvents that lead to contamination of the film. Using products that contain solvents to clean the surface can damage the surface, as cracks will appear on it that cannot be removed. In addition, do not use cleaning products that contain acids and clean the surface by abrasion. It is not advisable to use cleaning products that evaporate quickly. Such products can noticeably damage the surface of your facade. Do not wipe the surface with abrasive cloths and sponges for washing dishes, so as not to scratch the acrylic surface. It is contraindicated to clean the surface with steam, a large amount of moisture can also damage the surface. Therefore, remember that it is necessary to clean the surface of the facade with soft cloths soaked in 1% soap solution and a special ULTRA-GLOSS + DGS agent, which, in addition, also polishes the scratches that have appeared.
Photographic products. It is necessary to wipe products with photo printing with a damp soft cloth, it is also possible to wash with a light soapy solution. When cleaning, exclude the use of abrasive powders and hard metal or hard brushes containing abrasive chips. Avoid aggressive cleaning agents containing acids, solvents and salts. In order to preserve the original appearance and consumer properties of products with photo printing, we DO NOT RECOMMEND the following operating conditions:
- The use of products for outdoor decoration outdoors, where there is a possibility of large temperature differences and negative air temperatures.
- Use for facing fireplaces, where the temperature can reach 100-120 degrees C.
- Careless handling - falls and bumps, rough mechanical loads, which result in cracks, chips, deep scratches and, as a result, the integrity of the protective layer of the product is violated.
- Transportation associated with temperature fluctuations, entailing condensation on the surface.
- Visually for at least 30 seconds;
- Without the use of magnifiers;
- In daylight or identical to daylight;
- At a distance of 1 m at an angle of 90 degrees to the surface of the product.
- ensuring personal presence at the place of execution of the contract or another person indicated as a possible recipient of the goods.
- expiration of the warranty period;
- non-compliance with operating conditions;
- the presence of mechanical damage and defects on the product, traces of foreign interference in the product resulting from improper operation, unskilled assembly, repair and transportation;
- exceeding the permissible loads on the product;
- causing damage to the product as a result of intentional or erroneous actions of the consumer;
- causing damage to the product caused by the ingress of foreign objects (liquids, animals, insects, etc.) into the product;
- Warranty obligations do not apply to swelling of the laminate as a result of improper use of furniture, for example: under the influence of water or steam, high temperature, strong radiation sources, etc.;
- causing damage to the product as a result of making changes to its design;
- use of the product for industrial purposes.
- features due to the texture of the material or style of the product, such as slight (not conspicuous) color differences or differences in the texture of the elements of the product;
- a slight color difference between the elements of the product and the samples presented in catalogs and other printed products, which is determined by the peculiarities of printing;
- a slight color difference between the elements of the product and the samples exhibited at retail outlets, since the color of the surfaces during storage and operation may change;
- for the reasons stated above, a discrepancy in color with previously purchased furniture for replacement elements or elements for additional orders is not a defect;
- normal abrasion of the coating in places of frequent contact;
- loosening of joints, reduced mobility of hinges and locks, complications in the movement of doors and drawers in the process of constant use, caused by a lack of care for the product.
- Deviation from the nominal dimensions specified in the drawing and actual dimensions finished products within ±2-3mm due to different readings of measuring instruments.
metal surfaces. Do not use abrasive or corrosive agents or sponges coated with metal fiber or flaking material when cleaning. After cleaning, the effective gloss of the surface is given by polishing it with a soft dry cloth in a reciprocating motion.
Chromed surfaces. Chrome plating, unlike of stainless steel, does not allow contact with water. In order to prevent the occurrence limescale and oxidation (rust) on chrome surfaces when exposed to water, the surface must be wiped and dried.
Sliding doors. To maintain excellent appearance and durable performance sliding doors(closet systems) observe a few simple recommendations. Periodically clean the skids of the lower guides from dirt and dust with a vacuum cleaner, otherwise they are wound on the wheel and interfere with the smooth running of the doors. Do not expose system profiles and door filling materials to mechanical damage and chemicals not intended for this material. Be careful not to get large amounts of moisture into the sections of the sealant materials.
Helpful prevention. After a certain period of use, some mechanical parts (hinges, locks, etc.) may lose the optimal adjustment and lubrication made during the assembly of the furniture product. Such phenomena can be expressed in creaking, difficulty in opening doors or pulling out drawers. Therefore, when operating household furniture, do not use excessive force to open doors, drawers and other moving parts. Their proper operation is ensured by timely adjustment of the hinges or lubrication of the guide rails with paraffin or an agent of a similar quality. When loosening knots threaded connections they need to be tightened periodically.
FURNITURE DELIVERY
Represents the movement (loading, transportation, unloading, lifting, transport forwarding) of furniture from the place of its manufacture (acquisition) to the address indicated by the Customer (buyer).
It is recommended to use the delivery service provided by the Contractor (seller) or specialized organizations that have equipment, vehicles and personnel suitable for these purposes.
It is not recommended to make independent delivery of furniture products.
Remember: defects in furniture products resulting from self-delivery cannot be eliminated under warranty.
RECEPTION OF FURNITURE
When choosing (accepting) goods, be careful about the size, style and other similar qualities of furniture, since the right to exchange goods of good quality, provided for in Art. 25 of the Law of the Russian Federation "On Protection of Consumer Rights" of 07.02.92 2300-1, in accordance with Decree of the Government of the Russian Federation of 19.01.98 No. 55 does not apply to furniture.
The customer (buyer) undertakes to accept the furniture in terms of quantity and quality no later than the last day of the period agreed in the contract for the transfer of furniture. Acceptance of furniture is carried out at the place of execution of the contract by unpacking and inspecting it in the presence of a representative of the Contractor (seller). Checking is recommended to be carried out by opening the packaging of all items, by examining them. First of all, front panels, mirrors, glass surfaces, etc. in order to detect visible defects (scratches, chips, dents), significant differences in the texture and (or) shades of materials that make up a single surface (for this, the compared items are displayed next to each other) and the absence of accessories.
Requirements for the quality of the appearance of furniture. The requirements are developed in accordance with TU 5683-46275274-2007, GOST 20400-80 “Furniture production products. Terms and definitions”, GOST 16371-93 “Furniture. Are common specifications”, European standard EN 438 “Decorative high-pressure laminates”.
- In accordance with generally accepted standards, the quality of the appearance of the product is evaluated by normal conditions:
GENERAL TOLERANCES.
On the front, end and back surfaces of the product, any deviations are allowed that are not noticeable when assessed in normal conditions.
On the front surface: "shagreen" with a deviation from the plane of not more than 0.05 mm (barely noticeable when assessed under normal conditions).
On the reverse surface: embeddings in the amount of not more than 3 per 0.3 sq.m. no more than 6mm in size each (no more than 3 pieces on a medium-sized workpiece)..
Remember: acceptance of furniture without pointing out the defects of furniture products that could be established with the usual method of acceptance (obvious defects), deprive the Customer (buyer) of the right to refer to them in the future. It is not a shortcoming (defect) of the product that its elements contain features that are determined by the stylistic idea of the manufacturer of the raw materials, etc. Wrinkles on the facing material of soft elements that appear after the load is removed and disappear after smoothing (by hand) are also not a defect. The fact of acceptance is reflected in the Acceptance-Transfer Certificate (invoice) and is confirmed by the signature of the Customer (buyer). The customer (buyer) has the right to refuse to unpack and inspect the furniture, in which case the fact of refusal is reflected in the Transfer and Acceptance Certificate (invoice), claims for defects that could be detected during inspection are not accepted by the Contractor (seller).
The customer (buyer) ensures the proper conditions for the acceptance of furniture, including:
The customer (buyer) has the right to refuse to accept the furniture if, during the acceptance process, the furniture does not comply with the terms of the quality contract. The Customer (buyer) makes a note about the refusal in his own hand in the Transfer and Acceptance Certificate (invoice). In other cases, the refusal to accept the goods after the deadline for the transfer of furniture is unreasonable.
In the event that the Customer (Buyer) fails to ensure proper acceptance of the furniture, re-delivery (carried out through the fault of the Customer (Buyer)) is made within the terms agreed by the parties at the expense of the Customer (Buyer) on a prepaid basis.
FURNITURE ASSEMBLY
It is recommended to use the assembly service provided by the Contractor (seller), which has equipment, tools, technologies and personnel suitable for these purposes, since in this case the Contractor (seller) is responsible for the quality of the service provided. It is not recommended to make self-assembly furniture purchased in disassembled form, or its "repair", "improvement", as well as to resort for these purposes to the help of specialists of dubious qualifications. Obvious at first glance, the ease of assembly is apparent. Proper assembly requires professionalism (availability of the necessary knowledge and skills), knowledge technological features manufacturing of furniture products, properties of materials and structures, processing techniques, installation sequence.
Attention! In the case of an independent or unskilled assembly, not only the occurrence of defects in the products (their elements) and, as a result, the loss of the right to warranty service is possible.
WARRANTY
The contractor (seller) provides the Customer (buyer) with a guarantee for the manufactured (sold) goods within 12 months from the date of signing the Acceptance and Transfer Certificate (invoice) or the sale of furniture, provided that the consumer observes the conditions for transportation, storage, assembly and operation rules of furniture. Furniture defects identified during the warranty period, with the exception of those that arose through no fault of the Contractor (seller) (for example, if the Customer (buyer) violated the rules for operating furniture products) or about which the Customer (buyer) was warned in advance, before the transfer furniture will be removed free of charge. During the validity of the warranty obligations, the Contractor (seller) undertakes, within an objectively feasible minimum period after the Customer (buyer) discovers a defect, to repair or replace defective parts of the product. Warranty service is carried out only if there is a document confirming the order (purchase) of furniture in our furniture showroom. The operation of furniture is recognized as incorrect if there are sufficient grounds to assert that the furniture or its individual surfaces were subjected to mechanical, thermal stress, water or steam, aggressive agents or dyes, etc., as a result of which damage appeared at the impact points.
Warranty service is NOT CARRIED OUT in case of:
ATTENTION! Manufacturing defects of the product are not:

Requirements for the quality of furniture for sitting and lying are defined in GOST 19917-93.
The number of flaws allowed on solid wood parts depends on the type of surface: visible (front or inside) and invisible (outside or inside). Wood defects (knots, cracks, structural defects, fungal and biological damage), as well as mechanical damage are allowed depending on the type of surface, type of furniture (which includes the part), the nature of the surface treatment, the number and size of wood defects.
When lining parts, the wood fibers of the lining should be located at an angle of 45--90 ° relative to the fibers of the base wood, in some cases (established by the standard) a different arrangement of the veneer is allowed.
The back and seat of seating and lying furniture products can be soft or hard. Rigid furniture elements include elements without flooring or with flooring up to 20 mm thick.

Sofa bed in bed position: With a flexible base made of curved glued plates located over the entire area of the bed, with a mattress With a hard base and soft elements made of spring blocks With various transformation schemes with various floorings and types of bases |
The back of the product, not used in the formation of a berth, can be hard or any category of softness that differs from the softness category of the seat. The softness of the backrest, inserts and folding elements, which, when forming a bed, are located at the feet or at the head, may differ by one or two categories from the softness of the central element. The back of a sofa bed, which transforms into a “bed” position along the width of the bed, must have the same softness category as the seat.
Upholstered pieces of furniture lined with fabric and formed from foam rubber or multiple flooring materials, where upper layer- foam rubber, must have an additional flooring layer with a thickness of at least 3 mm from rolled or plastic materials made from natural fibers. When forming soft elements from foam rubber with natural or artificial leather lining, an additional flooring layer is not required.
Children's mattresses made of elastic polyurethane foam must have a batting layer of at least 3 mm thick on both sides. Seams on the pillowcases of children's mattresses are only allowed on the sides.
In soft furniture elements, elastic roll and plastic materials should be used as flooring. It is allowed to form a flooring layer from loose materials with laying between the panels of the cover material, obligatory stitching and fastening.
Soft elements based on spring blocks during operation should not make noise in the form of clicks and creaks.
It is not allowed to use rubber bands, tapes and fabric panels in the bases of beds.
For plugs in the bases of upholstered furniture elements, plywood or hardboard should be used. It is allowed to use a plug, consisting of several parts, with joints located on the middle of the frame or base box. Each part of the plug must be fixed around the perimeter.
On a rigid base under the spring blocks, a layer of cotton wool, batting, cotton wool or other layered or roll material not less than 5 mm thick.
Facing materials must be carefully selected in terms of pattern and color, both for individual products and for parts that are part of a headset or set.
The facing material must be stretched in compliance with the symmetry of the pattern, without wrinkles and distortions.
Wrinkles on the cladding material that appear after the load is removed and disappear after light smoothing by hand are not taken into account. The folds on the facing material, due to the artistic solution of the product, must be provided for in the technical documentation for the product.
The sides, edges and seams on the front surfaces of the soft elements should not have irregularities, distortions and crooked lines. Seams on the front surface of soft elements are not allowed, except in cases provided for by the documentation for the product.
In furniture products with bases made of wood or wood-based materials, it is recommended to fasten the covering and facing material, except for removable covers, with staples or glue. When fastening with staples or nails on all surfaces, with the exception of surfaces in mating joints, it is recommended that the facing fabric, in the absence of edges, be tucked around the edges or overcast on an overcasting machine.
The facing material of the soft elements at the corners must be straightened and sewn up with threads matched in color. For chairs, work chairs, banquettes and benches in upholstered elements up to 50 mm high, the facing material can be tightly tightened at the corners without stitching.
On invisible surfaces and internal visible surfaces of soft elements, it is allowed to replace the facing material with another material that is not inferior to the standard sample in terms of strength.
The design of products with compartments for storing bedding should ensure that the soft elements are fixed in a position that opens access to the compartments for storing bedding.
The ribs in children's furniture products that a person comes into contact with during operation must be softened.
Transformable, retractable and sliding elements of products must have free movement without jamming and distortion. During the operation of transformable products, their safety for human life and health must be ensured, provided that the operating rules are observed.
Maximum deviations from the overall dimensions of products should not exceed +5 mm. For furniture, the overall dimensions of which are determined by the dimensions of the soft element (except for chairs and mattresses), the maximum deviations from the overall dimensions should not exceed ± 20 mm. For chairs and mattresses, these limit deviations shall not exceed ±10 mm. The maximum deviations of the overall dimensions of products, determined by parts made of metal, plastic or bent-glued parts, should not exceed those specified in the technical documentation for the product.
