Sewing depends on whether the stitches are even and straight, and the two hands are firmly pressed to see if the seams are tight and the sides of the teeth are round and full. In addition, here are some key points to check:
Look at frame quality
Both hands will shake the whole piece of the sofa back and forth and shake it vigorously. If it feels better, the frame is firm. Then discuss with the sales staff, uncover the corner of the lower base cloth, if there is no bad, no insects, no scars, no bark or wood wool, the hard and hard wood is made, and the connection between the material and the material is not Nailed with nails, but with a blink or a bite, and then glued, there is no problem.
Look at the quality of the inner cushion

This cushion rebounds well and feels comfortable. The mid-range sofa is mainly made of rubber fiberboard as the base and the bottom of the back. The upper layer is layered with medium density foam and sprayed cotton. This cushion has a harder sitting feel and a slightly less resilience.
Look at fabrics, sewing
Buy a leather sofa to choose a leather surface. The leather sofa is divided into a full-skin sofa and a half-skin sofa. Each set of leather sofas consumes 10 cows of cows. It has high value, good ventilation and environmental performance. It is widely used in developed countries such as Europe and America. The semi-leather sofa replaces the cowhide with PU leather or artificial leather PVC on the back, bottom and other hidden parts of the sofa, but the direct contact part of the human body is still a higher value cowhide, which reduces the cost of the sofa and is more economical. The sofa skin is divided into yellow cowhide and buffalo leather, which are divided into top layer skin, second layer skin and three layer skin according to the number of layers; according to the origin, it is divided into domestic skin and imported skin. Imported skin imported from Italy and Germany with the best quality of the top layer of yellow cowhide, meets strict environmental requirements, high color fastness, good elasticity and breathability, high mechanical strength, especially high tear strength and tensile strength. High quality leather sofas must be made of the first layer of yellow cowhide. When purchasing a leather sofa, the leather surface should be rich and lustrous, no scars, and the texture of the texture should be fine. Use a fingertip to pinch a place to the top. It should be soft and strong. After the sitting, the wrinkles can be disappeared or not obvious. The leather is fine and good.
Look at the cloth
The cloth should be seen whether the fabric is tightly attached to the inner filling, whether it is flat and flat, especially the two handrails and the joint of the seat and the back should be natural and without creases. If it is a round and semi-circular handrail, it is necessary to see whether the arc is smooth, plump and beautiful. The fabric of the floral pattern or the checkered pattern depends on whether the flower shape of the splicing is consistent, whether the square is horizontal and vertical, and there is no inclination or distortion. Finally sit down and try it out. I feel if the inclination of the seat and back or the curvature of the back seat are the same as the waist, back, buttocks and leg bends. Is the height of the pillow and the back right? The arms naturally stretch and open in the usual time; the sitting feel is comfortable, and it is free when standing up. Stand up and look at the fabric on the buttocks, backrest and armrests for pleats that are noticeably slack and can't be recovered for a long time.
Look at the choice of foam sponge
High-grade sofa cushions should use high-elastic foam sponges with a density of 30 kg/m3 or more. The back cushions should use high-elastic foam sponges with a density of 25 kg/m3 or more. In order to improve the comfort of sitting and lying, some foams are soft-treated under the premise of ensuring no reduction in density, and some are provided with vertical springs in the seat cushions, so that the sofa has higher resilience and anti-aging properties. Under normal circumstances, the human body sits down after the sofa cushion is about 10 cm recessed.
