Shake the whole sofa with both hands. If it feels good, it means that the border is firm.
Then discuss with the sales staff and uncover a corner of the seat bottom cloth. If there are no rotten, moth-eaten, scarred, smooth and hard miscellaneous wood without bark and wood threads, the joints between materials will not be nailed, but interlocked with tenons or notches, and then glued firmly, there will be no problem.
2. Look at the quality of the inner pad.
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.
Step 3 look at the fabric and sew
When buying a leather sofa, the leather surface should be shiny, scar-free, and the lines are delicate. Hold a place with your fingertips and pull it up. Be flexible and powerful. After sitting down, wrinkles can disappear or not be obvious. This kind of leather is the best leather.
When purchasing fabric sofa, it should be noted that the seat ring and back cover of the sofa should be cuff structure. High-grade fabric sofas are generally lined with cotton cloth, and other easily soiled parts should be washable.
When buying fabric sofas, you should choose fabrics with delicate latitude and longitude lines, no jumpers, no exposed joints and strong hand feeling.
Sewing to see whether the stitches are even and straight, hands to see whether the seams are tight, and whether the edges of teeth are round and plump.
4. Look at this cloth
The wrapping depends on whether the fabric closely fits the inner filler and whether it is smooth and crisp, especially the joint between the two handrails and the seat back should be naturally wrinkle-free.
If it is a circular or semi-circular handrail, it depends on whether the radian is smooth, plump and beautiful.
Fabric with pattern or checkered pattern depends on whether the pattern at the splicing place is consistent, whether the squares are horizontal and vertical, and whether there is inclination or distortion.
Finally, sit down and have a try, and feel whether the inclination angle between the seat and the back or the radian above the back seat is closely consistent with the bending of the waist, back, hips and legs; Whether the height of the pillow and backrest is appropriate, and whether the height of the armrest is consistent with the natural extension of the arm; Whether it is comfortable to sit or stand.
After standing up, look at the fabric of hips, back and handrails to see if there are obvious loose folds that cannot be recovered for a long time.
5. Look at the choice of foam sponge
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.
In general, the sofa cushion should be sunken about 10 cm after sitting down.
