An elastic mattress partitioning softness and hardness comprises at least two groups of spring modules with different elasticities and hardnesses. An inner side of each of the spring modules comprises a plurality of spring members that are spliced together, and each of the at least two groups of the spring modules comprises the plurality of spring members with at least one elasticity and hardness. Each of the spring modules defines an interlaced or array arrangement by the plurality of spring members through the connecting structures, and the spring modules with the different hardnesses in the elastic mattress are assembled in any section in the elastic mattress. A hardness of one or more of the plurality of spring members disposed in an edge section of the elastic mattress is greater than a hardness of one or more of the plurality of spring members in another section of the elastic mattress.

A mattress assembly includes a base core layer and an inner core located over the base core layer. The inner core includes coil springs. The mattress assembly also includes a side panel assembly located around a perimeter of the inner core. The side panel assembly includes a spacer fabric located over and transverse to the base core layer. The spacer fabric includes a first knit layer, a second knit layer, and an inner fibrous material located therebetween. Methods of forming the mattress assembly are disclosed.

A mattress assembly includes a base, coil springs over the base, and a side panel around at least a portion of the coil springs. The side panel includes a spacer fabric including a first knit layer, a second knit layer, and a fibrous material between the first knit layer and the second knit layer. Methods of forming the mattress assembly are also disclosed.

An elastic cushion and an elastic module unit for furniture. The elastic module unit configured for assembling into an elastic cushion, the elastic module unit comprising a fixed base plate and a plurality of elastic modules disposed on the fixed base plate; wherein a side edge of the fixed base plate is provided with a second connecting structure configured to releasably connect an edge fastening device which releasably connects a pad layer of the elastic cushion with the second connecting structure such that the elastic cushion can be formed as an elastic cushion with fully opened sides by means of the edge fastening device, thereby improving the comfort of the elastic cushion, improving the ventilation of the elastic cushion, meanwhile facilitating assembling and disassembling of the elastic cushion, and effectively reducing the storage space of the elastic cushion.
