In an exemplary embodiment, two seat base frames 1 are arranged, and the adjacent sides of the two seat base frames 1 can be detachably connected through the torx handle screws 8. The backrest 5 is detachably connected to the rear side of each seat base frame 1. When in use, the two seat base frames 1 are fixed with the torx handle screws 8 to form a two-person sofa for use, or the two seat base frames 1 are disassembled from each other to form two one-person sofas for use. Even they can be combined with a chaise lounge type sofa for use. In addition, the number of the seat base frames 1 can also be three to form a three-person sofa, or four to form a four-person sofa, both of which can be combined, disassembled or combined with the chaise lounge type sofa in the way the same as the two-person sofa. Therefore, the structure for use is flexible.
The sofa base also comprises a footrest base frame 3 combined with or fixed with the torx handle screws 8 at the front side of the seat base frame 1
The footrest base frame 3 can be arranged at the front side of any seat base frame 1. When located at the front sides of the seat base frames at both sides, the footrest base frame 3 forms a chaise lounge type sofa with the corresponding seat base frame 1.
