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 internal) and invisible (external or internal). Wood defects (knots, cracks, structural defects, fungal and biological damage), as well as mechanical damage are allowed depending on the type of surface, the type of furniture (which includes the part), the nature of the surface treatment, the number and size of wood defects.

When veneering parts, the wood fibers of the veneer must be located at an angle of 45-90 ° with respect to the wood fibers of the base; in some cases (established by the standard), a different arrangement of veneer is allowed.

The back and seat of seating and reclining furniture items can be soft or hard. Rigid furniture elements include elements without flooring or with flooring up to 20 mm thick.

The back of a product that is not used in the formation of a berth can be hard or any softness category other than the seat softness category. The softness of the backrest, inset and folding elements, which, when forming a berth, are located in the legs or at the headboard, may differ by one or two categories from the softness of the central element. The back of a sofa bed, which can be transformed into a “bed” position along the width of the berth, must have the same softness category as the seat.

Soft pieces of furniture lined with fabric and formed from foam rubber or several flooring materials, where the top layer is foam rubber, must have an additional flooring layer with a thickness of at least 3 mm from roll or sheet materials made of natural fibers. When forming soft foam rubber elements with natural or artificial leather cladding, an additional flooring layer is not required.

Children's mattresses made of elastic polyurethane foam must have at least 3 mm thick batting on both sides. The seams on the pillowcases of children's mattresses are only allowed on the sides.

In soft elements of furniture, elastic roll and sheet materials should be used as flooring. It is allowed to form a flooring layer from loose materials with laying between the panels of the covering material, mandatory quilting and fastening.

Soft elements based on spring blocks during operation should not emit noise in the form of clicks and squeaks.

It is not allowed to use rubber bands, tapes and fabric panels in bed bases.

For plugs in the bases of upholstered furniture elements, plywood or hard fibreboard 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, wadding or other plastic or roll material with a thickness of at least 5 mm must be laid.

Facing materials should be carefully selected according to the pattern and color, both for individual products and for parts that make up a headset or set.

The facing material should be stretched in compliance with the symmetry of the pattern, without wrinkles and distortions.

Wrinkles on the facing material that appear after stress relief and disappear after light smoothing by hand are not taken into account. Folds on the facing material, due to the artistic solution of the product, should be provided for in the technical documentation for the product.

Beads, edges and seams on the front surfaces of soft elements should not have irregularities, distortions and crooked stitches. Seams on the front surface of soft elements are not allowed, except as provided by the product documentation.

In furniture products with bases made of wood or wood-based materials, covering and facing material, in addition to removable covers, is recommended to be fastened 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 along the edges or overcast on an overcasting machine.

The facing material of soft elements at the corners should be straightened and sewn up with threads of the same color. For chairs, work chairs, benches and benches in soft elements up to 50 mm high, the facing material can be tightly tightened in the corners without stitching.

On invisible surfaces and internal visible surfaces of soft elements, replacement is allowed facing material other material that is not inferior to the reference sample in terms of strength.

The design of products with compartments for storing bedding should ensure that soft elements are fixed in a position that allows access to the compartments for storing bedding.

Ribs in children's furniture products that a person comes into contact with during operation should be softened.

Transformable, retractable and sliding elements of the products must have free movement without jamming and distortions. During the operation of transformable products, their safety for human life and health must be ensured, subject to the rules of operation.

Limit 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 should not exceed ± 10 mm. Limit deviations of the overall dimensions of products, determined by metal, plastic or bent-glued parts, should not exceed those specified in the technical documentation for the product.

Parts and assembly units of products supplied to the consumer in disassembled form must be manufactured with precision, ensuring repeated assembly and disassembly of products without additional adjustment.

Facing materials, a group or category of protective and decorative coatings, the shape of furniture for public premises are recommended to be selected taking into account their systematic cleaning with a wet method or a vacuum cleaner.

Requirements for the quality of furniture for sitting and lying are defined in GOST 19917-93, where many quality indicators coincide with those listed above.

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, the type of furniture (which includes the part), the nature of the surface treatment, the number and size of wood defects.

Humidity of parts made of wood and wood materials, the strength of the adhesive bond for uneven separation, norms of wood defects for surfaces lined with veneer, requirements for surfaces in terms of lining defects (according to GOST 20400), plywood furniture parts, facing materials, coatings, roughness, warping parts and control methods for these indicators are established by GOST 16371, i.e. are similar to those considered in section 2.3.2.

Requirements for the tolerances of defects and plugs for their sealing on different surfaces parts made of wood, depending on their size and type of facing material, as well as in spike joints and parts carrying power loads, are anatogical to the requirements discussed in clause 2.3.2.

When veneering parts, the wood fibers of the veneer must be located at an angle of 45-90 ° with respect to the wood fibers of the base; in some cases (established by the standard), a different arrangement of veneer is allowed.

The back and seat of seating and reclining furniture items can be soft or hard. Rigid furniture elements include elements without flooring or with flooring up to 20 mm thick. The softness categories of upholstered furniture elements are determined depending on the deformation value of the soft element under a load of 70 daN and on the compliance value (measured in mm / daN). For example, elements of the highest softness category - 0 under a load of 70 daN are deformed by at least 120 mm, and their compliance is from 2.4 to 4.2 mm / daN. In total, five categories of softness have been established: 0, V. Elements of the lowest category of softness - V - under a load of 70 daN are deformed by only 15–45 mm, and their compliance is in the range of 0.2–0.4 mm / daN. Categories of softness for soft elements of children's furniture are not established.

The softness categories of soft elements depend on the functional purpose of the product, as defined in GOST 19917-93. For example, elements of furniture for resting in a sitting position can have 0 - V categories of softness (armchair and sofa), - V (bench, pouf) and V (only benches). Soft elements (seats) of furniture for sitting and short-term rest (chair, office chair, stool) can be of category V. Softness categories for furniture for various purposes are recommended in accordance with the requirements

ergonomics, i.e. creating the most comfortable conditions for work or leisure.

The back of a product that is not used in the formation of a berth can be hard or any softness category other than the seat softness category. The softness of the backrest, inset and folding elements, which, when forming a berth, are located in the legs or at the headboard, may differ by one or two categories from the softness of the central element. The back of a sofa bed, which can be transformed into a “bed” position along the width of the berth, must have the same softness category as the seat.

Soft pieces of furniture lined with fabric and formed from foam rubber or several flooring materials, where the top layer is foam rubber, must have an additional flooring layer with a thickness of at least 3 mm from roll or sheet materials made of natural fibers. When forming soft foam rubber elements with natural or artificial leather cladding, an additional flooring layer is not required.

Children's mattresses made of elastic polyurethane foam must have at least 3 mm thick batting on both sides. The seams on the pillowcases of children's mattresses are only allowed on the sides.

In soft elements of furniture, elastic roll and sheet materials should be used as flooring. It is allowed to form a flooring layer from loose materials with laying between the panels of the covering material, mandatory quilting and fastening.

Soft elements based on spring blocks during operation should not emit noise in the form of clicks and squeaks.

It is not allowed to use rubber bands, tapes and fabric panels in bed bases.

For plugs in the bases of upholstered furniture elements, plywood or hard fibreboard 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, wadding or other plastic or roll material with a thickness of at least 5 mm must be laid.

Facing materials should be carefully selected according to the pattern and color, both for individual products and for parts that make up a headset or set.

The facing material should be stretched in compliance with the symmetry of the pattern, without wrinkles and distortions.

Wrinkles on the facing material that appear after stress relief and disappear after light smoothing by hand are not taken into account. Folds on the facing material, due to the artistic solution of the product, should be provided for in the technical documentation for the product.

Beads, edges and seams on the front surfaces of soft elements should not have irregularities, distortions and crooked stitches. Seams on the front surface of soft elements are not allowed, except as provided by the product documentation.

In furniture products with bases made of wood or wood-based materials, covering and facing material, in addition to removable covers, is recommended to be fastened 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 along the edges or overcast on an overcasting machine.

The facing material of soft elements at the corners should be straightened and sewn up with threads of the same color. For chairs, work chairs, benches and benches in soft elements up to 50 mm high, the facing material can be tightly tightened in 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 reference sample in terms of strength.

The design of products with compartments for storing bedding should ensure that soft elements are fixed in a position that allows access to the compartments for storing bedding.

Ribs in children's furniture products that a person comes into contact with during operation should be softened.

Transformable, retractable and sliding elements of the products must have free movement without jamming and distortions. During the operation of transformable products, their safety for human life and health must be ensured, subject to the rules of operation.

Limit 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 should not exceed ± 10 mm. Limit deviations of the overall dimensions of products, determined by metal, plastic or bent-glued parts, should not exceed those specified in the technical documentation for the product.

Parts and assembly units of products supplied to the consumer in disassembled form must be manufactured with precision, ensuring repeated assembly and disassembly of products without additional adjustment.

Facing materials, a group or category of protective and decorative coatings, the shape of furniture for public premises are recommended to be selected taking into account their systematic cleaning with a wet method or a vacuum cleaner.
