One of the biggest complaints about visco-elastic foam is that it gets very hot. Don't want to sleep in a furnace, but want the joys and comfort of sleeping on memory foam?
Though there are a few ways to make your mattress or mattress topper cooler, there really is little that you can do to cool down your mattress in a permanent way. Visco-elastic memory foam uses body heat to contour, which is the reason so many people love the material. When heat triggers the foam, it spreads air from the pores below you into surrounding parts of the mattress, leaving you in a warm little you-shaped nest. Great for restful sleep, but uncomfortably warm in many cases. Unfortunately, the high density of the foam causes it to absorb a lot of your body heat, and there simply aren't enough pores to release the warm air from other parts of the mattress.
Down Matress Topper
If you already have a visco-elastic mattress and are looking for a quick fix to your heat problem, try getting a breathable mattress cover to act as a barrier between you and the foam. If you are in the market for a new mattress or mattress topper and are researching potential problems with memory foam, you'll love to know that a new type of foam is on the market that completely destroys the all too common problem of overheating.
Complaints about overheating in memory foam mattresses are why ViscoFresh foam was invented. ViscoFresh used the formula of visco-elastic foam as a starting point, but added more pores in the material to actually keep the user cooler at night. In fact, ViscoFresh memory foam is three times more breathable than visco-elastic foam. It offers the best of both worlds: the responsiveness to mold to the shape of your body for a comfortable night's sleep, but enough breathability to keep you cool even on the hottest nights.
