① The frame structure of the sofa should be firm, and the firmness of the skeleton determines the service life and quality of the sofa. We can lift one end of the sofa about 8cm from the ground to see if the other end is off the ground. If it is off the ground, it means that the skeleton structure is solid.

(2) You can also shake the sofa repeatedly with both hands. If you feel better, it means that the frame is firm. Then look at the bottom of the base fabric. There must be no decay, moth-eaten, scars, burrs, etc.

2, sofa comfort:

The sofa has a great function, which can be used as a chair or a bed. Generally speaking, when buying a sofa, it is best to sit on the spot and feel its hardness. If the sofa is too hard, sitting will cause muscle aches, while if the sofa is too soft, the whole person will be trapped inside, and sitting for a long time will be uncomfortable.

In addition, when choosing a sofa, the comfort of the sofa is also reflected in its size. The size of each part of the sofa should conform to ergonomics and the curve of human body structure, so that it will be more comfortable whether sitting or lying down.

1. The height of the sofa is preferably between 35 and 35-40 cm, which is the position of the human calf. Too high or too low is not conducive to the relaxation of human muscles, and long-term use is easy to cause body aches.

2. The depth of the seat is about 46-50cm.

3. The inclination of the sofa backrest can be between 100- 108 degrees.

The height of the armrest is about 20 cm above the sofa.

3, sofa filling material:

The quality of filling materials in sofa is related to the service life and comfort of sofa. We can choose to press the armrest and backrest of the sofa by hand. If you can clearly feel the support of the sofa, it means that there are too few materials inside. After we use it for a period of time, the sofa will become hard and even wear out the skin, exposing the border. So avoid choice.
