Which sofa is better, how to judge?

Classification 1 (classification by function).

It can be divided into functional sofas, fixed-back sofas, stepless automatic control sofas, pneumatic sofas (i.e., manual sofas), electric sofas and sofas with TVs.

Sofas have become an essential piece of furniture in many homes. There are generally three types of sofas sold on the market: low-backed sofas, high-backed sofas, and ordinary sofas in between. The following three characteristics are introduced separately for consumers to choose to buy.

Low-backed sofa: A light chair for resting. It supports the user's waist (lumbar vertebrae) with a support point, and the height of the sofa backrest is low, generally about 370 mm from the seat surface, and the angle of the backrest is also small, which is not only conducive to rest, but also reduces the size of the entire sofa periphery.

This sofa is easy to move, lightweight, and has a small footprint.

High-back sofa: also known as airline-style seat. It is characterized by having three fulcrums, so that the waist, shoulders, and back of the head are resting on the curved backrest at the same time.

These three support points do not form a straight line in space, so the technical requirements for making this sofa are high, and it is more difficult to choose when buying. To make a wooden frame for a high-backed sofa, it is necessary to clearly make a turning surface composed of three points on the shelf, otherwise it will be difficult to secure the position of the support point when carrying out the sofa masking and other processes, which will bring discomfort to the user. When choosing a high-backed sofa, it is necessary to pay attention to whether the composition of the three support points on the back of it is reasonable and appropriate, which can be judged by the test seat.

High-backed sofas evolved from recliners. In order to improve the resting performance, it can also be equipped with a footstool, which can be placed in front of the sofa at the same height as the front height of the sofa seat.

Ordinary sofa: It is a common type of sofa for home use. Most of the sofas sold in the market are of this type.

It has two support points to support the user's lumbar and thoracic vertebrae, and can achieve the effect of matching the curved surface of the back of the body. The angle between the back of this type of sofa and the seat surface is critical, and too large or too small the angle will cause the user's abdominal muscles to be strong and cause fatigue. Similarly, the width of the sofa seat should not be too large, usually within 540 mm according to the standard requirements, so that the user's calves can be adjusted at will to sit and rest more comfortably.
