[0002] A sofa is a multi-seat chair with cushions. A backrest chair equipped with springs or thick foam plastics, etc., has armrests on both sides and is a kind of soft furniture. Sofas have become essential furniture in many families. Generally, there are three types of sofas sold on the market: low-back sofas, high-back sofas, and ordinary sofas between the former two. Low-back sofas belong to lightweight chairs for rest. It uses one support point to support the user's waist. This type of sofa has a relatively low backrest height, is relatively convenient and light to move, and occupies a small area. High-back sofas are also called aviation seats. Its feature is that it has three support points, allowing a person's waist, shoulders, and back of the head to lean against the curved backrest simultaneously. Ordinary sofas are a common type among household sofas. Most of the sofas sold on the market are of this type. It has two support points to support the user's lumbar vertebra and thoracic vertebra, and can obtain the effect of a curved surface that matches the back of the body.

[0003] However, in order to achieve the weighing function of the sofa for users, that is, to enable the detection of the user's own weight when sitting on the sofa, there are sofas on the market that can bear weight.
