A chair includes a seat frame and a base frame each having a pair of rods coupled to a support frame by four couplers. Each of the couplers has a groove for engaging with the rods of the seat frame and the base frame. The seat frame and the base frame can be supported in parallel with each other when the rods are engaged in the grooves of the couplers. The seat frame and the base frame can be rotated to contact with the support frame when the rods are disengaged from the grooves of the couplers, so as to form a compact configuration.
