In addition to the bed, the sofa is the closest furniture to us. Although the sofa has a very close relationship with us, it is still necessary to choose the sofa that suits you according to your needs. The following are the different couch types for you.
1. Low-back sofa
The low-back living room sofa belongs to the rest-model deft chair. It supports the user's lower back with a support point.
Generally, the distance from the seat surface is about 370 mm, and the angle of the backrest is also small, which is not only conducive to rest but also reduces the peripheral size of the entire sofa accordingly. The sofa is easy to move, light, and small in size.
2. High-back sofa
A high-back sofa is also called an aviation seat. It is characterized by three fulcrums, which make people's waist, shoulders, and back of the head lean on the curved backrest at the same time. These three fulcrum points do not form a straight line in space. Therefore, the technical requirements for making this sofa are relatively high and it's difficult to make a choice.
To make the wooden frame of the high-back sofa, the turning surface formed by three points must be clearly made on the frame, otherwise it will be difficult to ensure the position of the support point during the process of masking the sofa, which will bring discomfort to the user.
When purchasing a high-back sofa, you should pay attention to whether the composition of the three support points on the back is reasonable and appropriate, which can be judged by trial sitting.
High-back sofas evolved from lounge chairs. In order to improve the rest performance, it can also be used as a footrest. Before placing the sofa, its height can be the same as the front edge of the sofa seat.
3. Ordinary sofa

Similarly, the width of the seat surface of the sofa should not be too large, usually within 540 mm according to the standard requirements, so that the user's can adjust the sitting posture at will and rest more comfortably.
The length of the three-seat sofa is generally 175 to 196 cm, the double sofa is 126 to 150 cm, and the length of the single sofa is 80 to 95 cm.
