Bed

Abstract

A bed is provided, including a support stand, a cover, a cover support, and an adjustment mechanism. The cover support is connected at a top of the support stand, and the cover is connected on the cover support to form a bed surface. The adjustment mechanism is configured to adjust a tense degree of the bed surface. Optionally, the bed can be further provided with a retaining mechanism to prevent the movement of the mechanism.
