An adjustable mattress topper assembly disposed in a cover is disclosed. The topper assembly may have one or two inflatable multi-valve bladder assemblies filled with foam; the topper assembly may be disposed in a topper body of foam. A hand-trigger may be used to operate a valve and inflate and deflate the bladder assembly, which may be located below the lumbar of a supine user.

A mattress having a three-dimensional elastic structure of the present invention has a structure in which a main elastic body independently contracts and expands by multiple first to fourth auxiliary elastic slits which intersect with each other in left and right directions, front and rear directions, and up and down directions so as to form a three-dimensional air tunnel. Accordingly, when the first to fourth auxiliary elastic slits contract and expand, air is discharged in all directions of the main elastic body through the three-dimensional air tunnel so as to disperse the pressure by a human body, thereby inducing good blood circulation, and heat is released through the three-dimensional air tunnel so as to secure air permeability, thereby inducing maintenance of a proper sleep temperature so as to provide a more comfortable sleep environment.

A three-layered topper fora bedding or seating product has a first piece of foam, a second piece of foam and a pocketed spring comfort layer therebetween. The pocketed spring comfort layer has individually pocketed mini coil springs. At least one of the foam pieces may be infused with metallic particles to improve thermal conductivity. Alternatively, at least one of the foam pieces may be infused with microencapsulated phase change materials to improve heat absorption. At least one of the foam pieces may have a coating to further improve thermal conductivity or heat absorption.

In some embodiments, a support structures can be formed from a support structure matrix comprising a plurality of layers and a plurality of spring structures embedded within the plurality of layers of the support structure matrix. The plurality of spring structures have a plurality of different durometers. The plurality of spring structures can be configured to deform and return to its original shape after deformation. The orientation and structure of the spring structures can vary depending on a desired durometer and/or function within the support structure.

Mattress assemblies including phase change materials and processes for dissipating retained in the mattress assemblies generally include a spacer layer in proximity to one or more foam layers containing a phase change material; and a pump in fluid communication with the spacer layer to provide a positive or negative air flow into the spacer layer to reduce retained heat in the phase change materials subsequent to a sleep cycle. The process includes operating the pump between sleep cycles to reduce the retained heat.

A foam pad structure having a protective film includes a substrate layer, a hot glue layer, a printed pattern layer, and an adhesive film. The substrate layer is made of a foam material. The substrate layer has two surfaces arranged oppositely on its upper and lower sides. The hot glue layer is coated on at least one of the two surfaces of the substrate layer. The hot glue layer has an adhesive surface facing away from the substrate layer. The printed pattern layer is composed of a pigment containing the same composition as the hot glue layer. The printed pattern layer is printed on the adhesive surface of the hot glue layer. The hot glue layer and the printed pattern layer are melted between the substrate layer and the adhesive film.
