PROBLEM TO BE SOLVED: To provide furniture with casters, such as a low floor table with casters, which can be easily carried by anybody without damaging the surface of Tatami mats on the floor and keeps a good appearance as furniture. SOLUTION: A low floor table 1, for example, includes casters 4 at legs 2 on one side. The casters 4 are usually retracted and concealed inside the legs 2, project downward when the low floor table 1 is tilted with the other side up. When the other side is lowered and positioned at an inclination angle smaller than the inclination angle, the projecting rollers 4 are designed to bear the weight of the low floor table and roll to help the low floor table be moved. The casters 4 are unlocked when the low floor table 1 is tilted with the casters side up and then return to their retraction positions when the low floor table is put horizontally.
