A spring module for a spring cushion for furniture. includes a base (20), an end cap (30) and a spring (10) arranged between the base and the end cap. The end cap has a flexible connection portion (33) and is configured to be detachably fixed to the base (20). The flexible connection portion (33) is located radially inside the spring (10). The spring module provides improved stability. The spring cushion has a simple structure and is easy to assemble and disassemble. The disassembled spring modules can be compressed or stacked and nested to save storage and transportation space

A foldable base plate of an elastic mattress, the foldable base plate includes a plurality of mounting modules, the plurality of mounting modules and connecting modules are alternately spliced to form the foldable base plate, the plurality of mounting modules are disposed with tapered positioning members, the tapered positioning members are protruding cavity structures extending upward from the plurality of mounting modules, the plurality of mounting modules and the connecting modules are configured to be folded along a vertical direction to form a stacked structure, and when the foldable base plate forms the stacked structure: two adjacent ones of the plurality of mounting modules are connected by plugging through corresponding ones of the protruding cavity structures, and a corresponding one of the protruding cavity structures on a lower mounting module is inserted into a corresponding one of the protruding cavity structures on an upper mounting module.

Disclosed is an adjustable height box spring having a first upper bed frame, a first lower bed frame, and plurality of attachment units. The attachment units include a first rod and a second rod, collectively used to detachably attach the first lower bed frame with the first upper bed frame. The adjustable height box spring further includes a second upper bed frame pivotally connected to the first upper bed frame, and a second lower bed frame detachably attached to the second upper bed frame. The adjustable height box spring further includes a third lower bed frame pivotally connected to the first lower bed frame, and a third upper bed frame detachably attached to the third lower bed frame. The pivot attachment allows the second upper bed frame rests on top of the first upper bed frame, and the third upper bed frame rests on bottom of the first lower bed frame, when folded.

An adjustable bed system includes a mattress and an adjustment mechanism. The mattress includes a head portion and a foot portion rearward of the head portion. The head portion defines a cavity that is downwardly open. The adjustment mechanism includes a lower base, an upper support that is movably coupled to the lower base, and an actuator operable to move the upper support relative to the lower base. The adjustment mechanism is positioned in the cavity and is coupled to the mattress. When the actuator is operated, the adjustment mechanism moves the adjustable bed system between a flat configuration in which the head portion is substantially coplanar with the foot portion and an inclined configuration in which the head portion is inclined relative to the foot portion.

A spring module includes a plurality of elastic units. Each of the plurality of elastic units includes a spring, a base, an upper cover, and an intermediate flexible strap. The upper cover includes a channel penetrating through the upper cover along a length direction of the intermediate flexible strap, so that the upper cover has translational freedom relative to the intermediate flexible strap in a direction toward the base, and the intermediate flexible strap is provided with a buckling member. When the spring is in a released state, the buckling member is located on an outside of the upper cover and below the upper cover. When the spring is in a compressed state, the buckling member is placed in the channel and is interlocked with the channel in a direction of releasing the spring.
