A rocking chair having an elongate flexible seat supported at opposite ends by a pair of oppositely inclined, diagonally disposed frames. Each frame includes a U-shaped tube interconnected connected by a plurality of cross members and is pivotally interconnected with the other at the sides of each intermediate the ends by pairs of upper and of lower siderails. The frames nest one within the other such that the chair may be folded into a compact unit for storage. A fold-out footrest nests within the other frames to act as a back support when the chair is used without the footrest deployed. A pair of wheels can be mounted to the front legs on reversible axles such that when the chair is pinned in the upright position the chair functions as a wheelchair. When the chair is in the folded position with the footrest deployed, the chair acts as a wheeled cart.
