1, panel furniture:
Mainly depends on whether there are scratches, indentations, blisters, degumming and peeling, glue marks and other defects on the surface of the plate; Whether the wood grain pattern is natural and smooth, don't feel artificial; For symmetrical furniture, we should pay more attention to the consistency and coordination of color and grain on the plate, which makes people feel that the symmetrical plate is like a piece of material. Rationality and firmness of connection points of furniture parts. If a piece of furniture is modular, its hardware connectors should be of high quality, and the tightness between the hardware itself and the furniture should be very ideal. For furniture with integral structure, every connection point, including horizontal and vertical connection points, must be tight without gaps and looseness. Another example is surface treatment, paint surface treatment, and the brown eyes of wood grain and wood must be presented with a three-dimensional effect. Where the surface of sealing paint is treated, the surface feels most like the top coat of piano. Whether it is clear oil, mixed oil, matt, high light or flat light, the cleanliness, smoothness and hardness of the paint surface must be very high. To see the veneer of logs, it is necessary to make the veneer surface smooth and not blister; There shall be no trace of complementary color on the veneer; The wood grain of the veneer is dense, there is no gap between splicing and splicing, and the pattern should be aligned accurately. No matter on a plane or in a corner, the color difference of a surface veneer should be very small except for the color difference. The plate is assembled by cutting saw, decorative edge sealing and parts. Its production quality mainly depends on the quality of cutting saw, edge and surface decoration and board port.
In the process of cutting and sawing, the plates for making panel furniture have quality requirements for straightness, verticality and angular alignment of plate parts. Generally speaking, the cutting and sawing process of plates is within 0.0 1mm per meter. After cutting and sawing, the plates that meet the precise requirements have a flat outline and good angular alignment, so that they will not tilt after being made into furniture. The precision of the saw blade in the cutting saw will also affect the quality of the end face and edge of the plate, and the defects of the cutting saw such as scratches, edges and corners will also affect the appearance quality of the plate furniture.
Edge and surface decoration mainly depends on whether the glue on the decorative parts is uniform, whether the bonding is firm, whether the trimming is smooth and smooth, whether the end faces of visible parts such as side plates, door panels and drawer panels of the parts are sealed, and no traces of bonding can be found on the edge contour of the decorated plates.
The assembly mainly depends on whether the tongue-and-groove at the drilling hole is exquisite and neat, whether the joint is firm after installation, whether there is any gap in the T-joint after the plane and the end face are connected, and whether there is any looseness after pushing. Whether the gap between the door and drawer is too large is generally required to be between 1mm-2mm, and whether the door and drawer can be opened and pushed open flexibly.
As long as the above conditions are met, it is good veneered furniture from the perspective of manufacturing technology.
2. Solid wood furniture
First of all, we must judge the tree species, which is a very important factor and directly affects the price and quality. Also observe the wood, open the cupboard doors and drawers, and observe whether the wood is dry and white, and whether the texture is tight and delicate. If it is made of particleboard, density board, primary molding board, etc., open the cupboard door or drawer and smell it to see if there is any irritating smell. There should be no big knots or cracks in the main stress parts, such as the stress reinforcement near the ground between columns. The structure is firm, the frame shall not be loose, and the tenon and material are not allowed to be broken. Wood-based panel components for furniture should be edge-sealed, and there should be no fewer pieces, missing nails or piercing nails in various installations. The strength of the board surface can be pressed with your fingers to feel the firmness of the board surface. One side of the material should be fixed with a well-shaped skeleton. If the skeleton is sparse, it will feel empty and unreal according to the surface, and the panel will vibrate greatly. The bottom of the drawer should be pressed by hand to test the strength. Generally, the bottom of the partition is multi-layered, and the partition with large area should be five-layered. Observe whether the drawer or door frame is tilted, whether the mortise position is crooked or whether the eye hole is too large and the tenon is not tight. Wood should be safe and stable. When two cupboard doors are opened at 90 degrees, gently pull them forward by hand, and the cabinets should not automatically turn forward. The door of the bookcase should be edged; Mirrors and dressing tables should be equipped with backboards, and the layering should fix the surface. Individual parts (such as legs and feet, drawers, doors or brackets, etc. ) must have enough support. You can nudge the corner or sit aside to see if it is firm. The heavier ones should be tightened and glued with protective blocks at the corners. As for the backboard, be sure to check whether the screws are embedded. Drawers should be strong and firm, and screws should be tightened inside. You might as well open drawers, movable desktops, cupboard doors and other parts to see if they can be used freely and connected correctly. Put your hand on the surface, and carefully check whether the polished surface is smooth, especially whether the table feet and other parts are rough, whether the paint coating is streaked, whether the paint on the corners is too thick, and whether there are cracks and bubbles.
When the panel is covered with veneer and other materials, it should be similar to the color of the complete set of products, and the paint film on the surface of the product is not allowed to wrinkle, stick to paint or leak paint. Without these problems, it should be solid wood furniture.
Second, how to choose a sofa
Sofa is mainly a frame structure, and the firmness of the structure and the rationality of the design angle will directly affect the quality and use function of sofa.
1, the choice of fabric sofa depends first on whether the overall structure is firm, loose, ergonomically designed, whether you can sit on the sofa and feel whether it is stable, the angle is reasonable and comfortable. Whether the sofa skeleton is strong or not is related to the service life and quality assurance of the sofa.
2. Look at elastic materials. Sofa is the most used and contacted furniture in people's rooms, and the quality of elastic materials affects the comfort and service life of sofa. Therefore, elastic materials should have strong compression resistance, good elasticity and high density, and you can try to touch them when you buy them to ensure product quality. Look at the quality of sofa padding. The specific method is to press the armrest and backrest of the sofa by hand. If you can clearly feel the existence of the wooden frame, it proves that the filling density of this sofa is not high and the elasticity is not good enough. The easily crushed wooden frame of sofa will also accelerate the wear of sofa cover and reduce the service life of sofa. Check the elasticity of the sofa. The specific method is to let the body sit on the sofa in a free-falling way, and the body will bounce off the sofa cushion at least twice, so as to ensure good elasticity and longer service life of the sofa.
3. Look at fabrics and matching. The close contact between fabric and human body directly affects the overall visual aesthetic effect. When purchasing, it should be consistent with the overall decoration style, and the colors should be clear and unified. It is necessary to distinguish the fabric type (jacquard or printed), origin (imported or domestic), performance (whether it fades, shrinks or pills) and environmental protection requirements. If you can touch the fabric by hand, the jacquard fabric has a strong sense of concavity and convexity, a strong three-dimensional sense and a slightly higher price, while the printing is relatively flat and the price is slightly lower. Open the zipper of the bolster, observe and touch the lining cloth and filler inside, and open the sofa to see whether the bottom treatment is meticulous, whether the sofa legs are straight, whether the surface treatment is smooth, and whether there are anti-slip pads at the bottom of the legs. Good sofas also maintain exquisite quality in details. Touch the surface of the sofa with your hands to see if there is skin irritation, and observe whether the fabric color of each part of the sofa is uniform, whether the seams are firm and flat, and whether the workmanship is fine.
4. Look at the price. With the above guarantee, the quality of fabric sofa depends on its price. The price of fabric sofa is high, medium and low.
Consumers should choose sofas according to the size of the room, the overall layout of the environment and their own economic conditions. In order to ensure the quality of the sofa, we can pay attention to the following aspects.
Sofa modeling should be beautiful and generous, and the color of fabric and the paint color of wooden handrails should be in harmony with the indoor environment.
The functional dimensions of the sofa should be reasonable, the width in front of the seat should be greater than or equal to 480mm, the height of the seat should be 360mm to 420mm, and the height of the armrest should be 250 mm.
The frame of the sofa should be tenon-mortise structure and cannot be connected with nails; The structure should be firm without any looseness, otherwise it will seriously affect the service life of the sofa.
The materials used in the internal structure of the sofa should be reasonable, and rotten, moth-eaten and mosquito-eaten wood should not be used. The moisture content of wood is generally 12%. Cannot exceed 13%. Springs should be rustproof, and gasket materials should be safe and hygienic. Old materials and moldy gasket materials should not be used.
When pressing the sofa by hand, there should be no obvious depression, no friction and impact between the springs, and the foam plastic of the sofa cushion or backrest should reach the density of 22 kg to 25 kg per cubic meter, and the feel should not be too soft. The fabric of the sofa should be clean and undamaged, and the stitching pattern should be complete without obvious color difference. The embedded line should be straight, and the spacing of foam nails should be basically equal and neat. The paint film of the exposed wooden part of the sofa should be smooth and uniform in color. Multi-layer curved wooden sofa should be inspected for glue opening defects.
At present, the bottom surfaces of high-grade sofa seats and backrests mostly use nylon belts and snake springs, and high-elastic foam, rubber-sprayed cotton and light foam are laminated on them. This kind of cushion has good elasticity and comfortable sitting feeling. Mid-range sofas are mostly based on bonded fiberboard and back, with medium density foam and glue-sprayed cotton laminated on them. This kind of cushion feels hard and has poor resilience. The wrapped fabric is closely attached to the inner filler, smooth and crisp, especially at the joint of two handrails, seat and backrest, which should be naturally wrinkle-free. If it is a circular or semi-circular handrail, the radian is smooth, plump and beautiful. The floral pattern or plaid pattern is consistent at the fabric splicing, and the squares are horizontal and vertical, without inclination or distortion. Finally, sit down and give it a try. I feel that the inclination angle of the seat back or the arc above the back seat is closely consistent with the bending of the waist, back, buttocks and legs. The height of the pillow and backrest is appropriate, and the height of the armrest is consistent with the natural extension of the arm; Sit comfortably and stand up freely.
High-grade sofa cushions should use high-elastic foam sponge with a density of more than 30 kg/m3, and cushions should use high-elastic foam sponge with a density of more than 25 kg/m3. In order to improve the comfort of sitting and lying, some foams have been softened without reducing the density, and some have vertical springs in the cushions, which makes the sofa have higher resilience and aging resistance.
