Abstract

A modular sofa chair addresses the technical problem mentioned in the background art: existing sofa chairs support the feet with footrests and are folded down by moving a movable base inside the chair. However, when the chair is folded down, the user cannot effectively support the lower legs, causing the thighs to contact the seat surface, resulting in pressure concentration on the ischial tuberosities and potentially causing hip pain. The modular sofa chair includes a seat body, a support frame for supporting the seat body, and a footstool. The support frame has two mounting blocks, and the footstool has two locking blocks. Each mounting block has a locking component for connecting and fixing the two locking blocks to the support frame. The footstool has a rotatable leg rest, and the footstool has an adjustment component for changing the rotation angle of the leg rest.
