What are the types of back chairs
1. Classical back chair
① hanging lamp chair
The lamp hanging chair is a kind of chair with a long history. It has appeared during the Five Dynasties. Gu Hongzhong's "Han Xizai Night Banquet" has such a chair. It was more common in the Song Dynasty. The top end of this kind of chair is protruded out at both ends, and some form a graceful and interesting bow shape, much like the beam of a bamboo oil lamp in rural areas in the south of the Yangtze River, so people call it a lamp hanging chair.
②Official hat chair
But in terms of its shape, in fact, the official hat chair and the hanging lamp chair are very close. It can even be said that the difference between the two lies in the presence or absence of handrails. As far as the overall shape is concerned, the hanging lamp chair is concise, light and practical, and is generally full of light. Later, it developed into a complete set with the simple and generous inner beauty.
The unified chair is also called the unified monument chair. This is a chair with a single back without armrests, which originated in the Ming Dynasty and flourished in the Qing Dynasty. Its main feature is that the back and the seat are at right angles, and the back and the hind legs are connected together. The upper and lower widths are the same, the back is rectangular and straight and straight, shaped like an ancient stele, so it is called a unified stele chair, or a unified chair for short.
2. Modern back chair
①Ordinary back chair
The ordinary back chair is evolved from the classical back chair, which is different from the classical back chair from the subtle changes in material and shape. The materials used are mainly a combination of solid wood and some modern metal materials.

2, lumbar support
When it comes to the comfort of a chair, the most important thing should be the lumbar support. The older you are, the more sensitive you are to this. The lumbar support looks simple, but the lumbar support is a high-tech part of the entire chair. There must be a complex mechanical mechanism connected to the entire chair. Of course, the real test method is to sit on your own, regardless of various postures. , Whether the back of the chair can completely wrap the back and support it.
3. Backrest tilt strength
