Look at the quality of the frame. With both hands, the whole sofa will be shaken and shaken repeatedly before and after, and 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 now the city is basically nailed, but with the blink of an eye or the mouth to bite each other, and then glued firmly, there is no problem. Estimates made in a blink or a mouth are rarely priced unless they are expensive, and the price is not cheap.
Look at the quality of the inner cushion. At present, the high-grade sofa seat and the bottom of the back are mostly made of a nylon belt and a snake spring cross-web structure, and the upper layer is layered with high-elastic foam, sprayed cotton and light foam. 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. Like some Internet cafes, the sofa manufacturers use springs as cushions, saving labor and cost. They are very soft when sitting, but they are not durable and have long-standing durability.
Look at fabrics and sewing. Buy a leather sofa to choose a leather surface. The leather sofa is divided into a full leather sofa and a half leather sofa. The leather sofa is of high value, breathable and environmentally friendly. The leather sofas are commonly used in developed countries such as Europe and America. The half-skin 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.
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 squat up. It should be soft and strong. After the sitting, the wrinkles can be disappeared or not obvious. The leather is fine and good.
