Disclosed are adjustable supports, bedding support assemblies, and foldable bed frames having adjustable supports, bedding support assemblies or both. A foldable bed frame includes first and second sub-frames, first and second leg assemblies, and one or more bedding support assemblies to support a bed cloth. First and second sub-frames are pivotally connected to each other at their proximal sides. First and second leg assemblies are pivotally connected with the first and second sub-frames, respectively. A bedding support assembly includes a bedding support, and one or more linking mechanisms to pivotally connect the bedding support with a sub-frame, a leg assembly or both. The bedding support assembly folds and unfolds along with the sub-frame and the leg assembly.

A corner connector for rod-shaped profile elements, with a connection element which comprises at least two attachment portions which are oriented substantially perpendicular to each other and which are each designed such that an attachment portion and a front end of the rod-shaped profile elements to be connected engage in each case one inside the other, at least one transverse strut of which the ends are designed such that an end of the transverse strut and a connection portion provided on a lateral surface of the rod-shaped profile elements to be connected in each case engage releasably one inside the other, and a clamping element which clamps the transverse strut releasably against the corner connector. An assembly system composed of such corner connectors and supporting or holding frames composed of such corner connectors and profile elements.

An electric bed capable of being assembled and dismantled without the need of using a tool is disclosed. The electric bed includes left and right modules, front and rear transverse beams having two ends bare-handed detachably mounted with the left and right modules respectively, and back, buttock, thigh and lower leg supporting units bare-handed detachably mounted with the left and right modules, respectively. A front actuator has two ends bare-handed detachably and pivotally connected with the front transverse beam and the back supporting unit, respectively. A rear actuator has two ends bare-handed detachably and pivotally connected with the rear transverse beam and the thigh supporting unit, respectively. As such, the electric bed can be easily and conveniently assembled and dismantled in accordance with the user's requirement and can be packed with minimized volume of packing material to reduce the transportation cost.
