1. Look at fabrics and sewing
When buying a leather sofa, the leather surface should be rich and shiny, without scars, and the texture and texture should be fine. Use your fingertips to pinch a place and pull up. It should feel flexible and strong. After sitting, the wrinkles can disappear or be indistinct after trimming. The leather is the best leather. When buying a fabric sofa, you should pay attention to it. The seat and back cover of the sofa should be a looper structure. High-end fabric sofas are generally lined with cotton cloth. Other parts that are easy to stain should be changed and washed. When buying a fabric sofa, you should choose a fabric with fine and smooth warp and weft, no skipping wires, no exposed joints, and a strong feel. Sewing depends on whether the stitches are even and straight, and the seams are tight with both hands and the edges of the teeth are round and plump.
2. Look at the choice of foam sponge
High-grade sofa cushions should use high-elastic foam sponge with a density of 30 kg/m3 or more, and back cushions should use high-elastic foam sponge with a density of 25 kg/m3 or more. 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, so that the sofa has higher resilience and anti-aging performance. Under normal circumstances, it is better to dent the sofa cushion about 10 cm after the human body sits down.
