An elastic mattress has a base layer, a plurality of elastic modules and a pad layer. The elastic modules are detachably arranged on a second surface of the base layer and are configured to directly contact the ground. The pad layer is arranged on a first surface of the base layer. Since the plurality of elastic modules are arranged on the second surface of the base layer and can directly contact the ground, the number of components of the elastic mattress is reduced and the structure simplified lowering the cost of the elastic mattress, while providing high comfort. Moreover, as the pad layer can be removed from the first surface of the base layer, the elastic mattress can be more easily moved and stored.

An inverted spring module splicing unit for a camping mat includes a plurality of independent spring modules. Each of the plurality of independent spring modules includes a conical spring sleeve and a conical spring, and the plurality of independent spring modules are spliced together in pairs through one or more third members. The one or more third members include one or more first connecting members and one or more second connecting members, and the one or more first connecting members and the one or more second connecting members form a detachable connection. The one or more third members are disposed at any position in an area from a middle of the conical spring sleeve to a large end of the conical spring sleeve, and the large end of the conical spring sleeve is configured as a pressure-bearing end of a corresponding one of the plurality of independent spring modules.

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. The arrangement of an adjustment mechanism allows the tense degree of a bed surface of the bed during use to be adjusted as needed and meanwhile makes it possible to facilitate product transport and simplify product installation.

A folding support and a folding bed are provided. The folding support includes a supporting crossbar and a folding assembly arranged at each of two ends of the supporting crossbar. The folding assembly includes a connecting base, an upper supporting rod, and a lower supporting rod. The connecting base is fixedly mounted at an end portion of the supporting crossbar. The upper supporting rod is rotatably connected to the connecting base. The lower supporting rod is rotatably connected to the upper supporting rod. The upper supporting rod and the lower supporting rod are configured to rotate in an identical plane to implement folding and unfolding of the folding assembly. When the folding assembly is folded, the upper supporting rod and the lower supporting rod are folded toward each other, and the upper supporting rod and the lower supporting rod are positioned adjacent to a side of the supporting crossbar.
