In assembly, first, the cover body 30 is respectively covered on the seat cushion 10 and the armrest 20, then the first, second zippers 33, 34 are respectively pulled to mesh together, thus the sectional sofa can be combined. Of course, when multiple seat cushions 10 are needed, the multiple seat cushions 10 can be assembled by the first zippers 33 pulled to mesh together. Since the compressible sectional sofa does not use non-deformable material such as metal or wood to fabricate, when transportation is needed, first the compressible sectional sofa is compressed by machine equipments to compress and discharge air, so that its volume can be reduced, and it is placed into a plastic bag or box, as long as the strength of the plastic bag or box should be larger than a resilience force of the compressible sectional sofa. During use, as long as the compressed sectional sofa is taken out of the plastic bag or box and unfolded using its inherent resilience force, it can be directly used.

Compared with the prior art, in the compressible sectional sofa provided by the present invention, since both the seat cushion 10 and the armrest 20 are made of compressible hard material and soft material, when transportation is needed, the seat cushion and the armrest can be compressed by machine equipments, such that air in the hard material and the soft material is squeezed out, and volumes of the seat cushion 10 and the armrest 20 are reduced, thus the package volume can be reduced to facilitate transportation; at the same time, during each transportation, the same container can be loaded three to four times more, thereby achieving the purpose of reducing transportation cost. At the same time, since the sofa is composed of the seat cushion 10 and the armrest 20, how to connect the seat cushion 10 and the armrest 20 and how to ensure the strength between the seat cushion 10 and the armrest 20 are very important, otherwise the compressible sectional sofa is unable to use. Therefore, the cover body 30 uses the zippers to fix the seat cushion 10 and the armrest 20; in order to improve the connection strength between the seat cushion 10 and the armrest 20, the first cloth strap outside surface 333 of the first zipper 33 abuts against and is sewn with the armrest outside edge surface 315, the second cloth strap outside surface 343 abuts against and is sewn with the top outside edge surface 314, and the opposite surfaces of the first cloth strap outside surface 333 and of the second cloth strap outside surface 343 are sewn, such that when one side of the second zipper 34 at the seat cushion 10 and another side of the second zipper 34 at the armrest 20 are pulling each other, the second zipper 34 has only the connection function, while has no pulling force for dragging, to the top surface 311 and the armrest side surface 312 on the seat cushion 10. In addition, since the opposite surfaces of the first and second cloth strap outside surfaces 333, 334 of the first and second zippers 33, 34 abut against each other, so that they have no function of dragging the top surface 311, thus not only is the seat cushion 10 seamlessly connected with the armrest 20, but also the strength between the seat cushion 10 and the armrest 20 is improved due to the mutually abutting caused by the seamless connection. Similarly, when two seat cushions 10 are connected together by the first zipper 33, there is also the above effect, thereby ensuring the connection strength between the two seat cushions 10.

The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, or improvement within the spirit of the present invention is covered within the claim scope of the present invention.
