[Problem] To lower a support table as much as possible, make the height between a base and the ground as low as possible, and make casters as large as possible. [Solution] In an adjustable
bed (1) according to the present application, the base of a
thigh support table (21) for supporting the thighs of a
lying person is inclinably provided on a support table (3), and the base of a shank support table (22) for supporting the shanks of the
lying person is provided at the tip of the
thigh support table (21) so as to be bendable up and down. When the support table (3) is lowered to the lowest with respect to the base (2) and the
thigh support table (21) is tilted, the base of the thigh support table (22) is bent at the end of the thigh support table (21), and when the support table (3) is lowered to the lowest with respect to the base (2) and the thigh support table (21) is tilted, the end of the thigh support table (22) slides along the thigh support tables (50, 57). In this way, the end of the crus support table (22) is lifted above a protruding member (
caster portions (10, 11), etc.) protruding from above the support table (3), so as to avoid a collision between the end of the crus support table (22) and the protruding member.
