<p>An elasticity adjustable bed includes a bed surface frame, a bed leg frame and a bed surface which covers and connects with the bed surface frame. The bed surface is made of elastic mesh cloth (9). The bed surface frame is a rectangular frame which is composed of four right-angled connectors (11) insert-connected with four bars (12). The right-angled connector (11) is composed of two butted tubes, and the ends of the two butted tubes have interfaces for the bars (12). Regulating bolts (13), which one end is screwed into a bar (12) or right-angled connector (11) and the other end is supported by a right-angled connector (11) or a bar (12), are set between a bar (12) and two right-angled connectors (11). The elasticity adjustable bed is characteristic of good permeability and high comfortable degree.</p> |
