A furniture system includes a tabletop and a leg. The tabletop has a chassis system defining a storage slot and including a leg mount defining a leg slot. The leg is receivable within the storage slot to support the leg within the chassis system in a stored configuration. The leg has head and foot end portions. The head end portion has first and second branches that are receivable within the leg slot. The first branch is separated from the second branch by a pivot channel to enable the first branch to pivot relative to the second branch. The second branch is engageable with a first end portion of the leg slot. The first branch is engageable with a second end portion of the leg slot after the second branch is engaged with the leg slot and after the first branch is pivoted relative to the pivot channel.

A folding desk includes a desk body and a desk board. The desk body includes four support mechanisms, two first linkage mechanisms and two second linkage mechanisms, the support mechanisms include upright rods and cross beam rods with ends hinged together, four upright rods are distributed in a rectangle, and first connection pieces slidable along the upright rods are disposed on the upright rods respectively. The two upright rods at short sides of the rectangle are connected by the first linkage mechanism. Two upright rods on long sides of the rectangle are connected by the second linkage mechanism, and each second linkage mechanism includes a second connection piece and four second linkage rods. Two cross beam rods on a same long side of the rectangle are placed on the second connection piece and located in a same straight line. The desk board is placed on the four cross beam rods.
