Referring to fig. 1 and 2, the present utility model provides a sofa seat frame with good elasticity, which includes a bracket 100 and a plurality of springs 200 arranged on the bracket 100 in parallel, wherein a mounting hole 300 is arranged in the middle of the bracket 100, and the sofa seat frame further includes a plurality of first connection structures 400, and the first connection structures 400 are fixed on the wall of the mounting hole 300; the first connection structure 400 includes a fixing member 410 and a connecting member 420; the fixing piece 410 is fixedly connected with the bracket 100, and two ends of the connecting piece 420 are respectively movably connected with the fixing piece 410 and the spring 200. Specifically, the bracket 100 is formed by connecting a plurality of support plates, and a plurality of support plates are enclosed to form the mounting hole 300. The spring 200 is arched, and the plurality of S-shaped structures inside the spring are pressed against each other when being stressed, thereby generating elasticity. Specifically, in actual use, the connecting member 420 may be pulled up by the unstressed spring 200 to be disposed horizontally or obliquely. When the arched spring 200 is stressed, the downward pressure it is subjected to eventually translate into a sideways pressure. Since the spring 200, the connecting piece 420 and the fixing piece 410 are movably connected in sequence, when the spring 200 is stressed, the middle part of the spring 200 is deformed downwards, the two wings of the arch spring 200 are expanded outwards, the pressure at the two sides of the spring 200 is transferred to the movable connecting piece 420, and the connecting piece 420 is also swung downwards. The pressure required by the deformation process is small, so that a user can obviously feel the elastic deformation process when sitting on the sofa, and the sitting feeling of the sofa is better. When the user gets up from the sofa, the arched spring 200 is restored, the middle portion thereof is protruded upward, both wings thereof are retracted toward the middle portion, and the connection member 420 is pulled to swing upward.
