There are some ways to cool your mattress and topper with foam coolers, but it is not much you can do that will permanently cool it down.
The foam coolers expands when heat is applied to it. This causes the foam to spread air from your pores into the surrounding areas of the mattress. It creates a cozy, you-shaped nest. It's great for a restful sleep but can be uncomfortable in some cases. The foam's high density makes it absorb a lot of heat from your body. There are not enough pores to let the warm air out of other areas of the mattress.
A breathable mattress cover can be used to protect your visco-elastic mattress from heat buildup. A new type of memory foam has arrived on the market, and it will be a great help to anyone looking for a mattress or a mattress topper.
The foam was created to address complaints about memory foam mattresses overheating. Fresh foam took the formula for elastic foam and added pores to the material to keep users cooler at night. The memory of this foam is three times more breathable than visco-elastic. It offers both the best of both: enough breathability to keep you cool on hot nights and the responsiveness to mold to your body so that you have a restful night of sleep.
