AI Technical Summary

Benefits of technology

[0007]The primary purpose of the present invention is to provide a built-up sofa having inflatable cushion and backrest. The parts of the sofa can be disassembled easily so as to reduce the space requirement and inconvenience in transporting and storing the sofa. The individual parts, on the other hand, can be replaced separately so as to reduce the cost of maintenance and to increase the recycling efficiency. Additionally, the cushion and backrest are mainly inflatable air bags whose degree of softness can be easily adjusted by inflating and deflating the air bags.

[0008]To achieve the foregoing features, a sofa of the present invention mainly contains a built-up seat frame which can be easily assembled and disassembled, an inflatable seat cushion positioned horizontally on the seat frame, and an inflatable backrest positioned vertically at a side of the seat cushion. The air faucets of the seat cushion and the backrest allow users to pump air into or release air from the air bags for an appropriate degree of softness.

Problems solved by technology

The frame usually has a sizable volume and weight, whose transportation and storage, in addition to the inconvenience, both take up quite a lot of space.

The conventional sofa also usually has the cushion and backrest fixedly joined to the frame so that, after a period of usage and some part of the sofa is aged and damaged, the entire sofa has to be replaced or discarded.

This is not only cost-ineffective, but also would present an environmental problem of a large number of junked sofas.

A user cannot adjust the softness based on his or her specific requirement.

The inflexibility would make the sofa less attractive to some people just because the degree of softness is not right for them.
