Mat with thermostatic layer between two layers of foam to reduce heat accumulation and method for making the same

A method for making a mat with a thermostatic layer between two layers of foam to reduce heat accumulation, comprising the steps of:

• positioning an air permeable foam layer on a processing platform;
• distributing a plurality of phase change material (PCM) microcapsules over a side of the air permeable foam layer by screen printing such that some of the PCM microcapsules enter pores in the air permeable foam layer;
• coating the side of the air permeable foam layer with a bonding material such that the bonding material surrounds the PCM microcapsules to form the thermostatic layer;
• and
• attaching a supporting foam layer to the thermostatic layer, wherein the supporting foam layer has two corresponding sides defining a first thickness therebetween, the side and a corresponding side of the air permeable foam layer define a second thickness therebetween, the second thickness is smaller than the first thickness, the pores in the air permeable foam layer are larger than pores in the supporting foam layer, and the supporting foam layer is bonded to the air permeable foam layer by the bonding material in the thermostatic layer.
