Who Should be Interested in Sleep Science Mattresses

If you are normally restless at night, tossing and turning looking for the best position to sleep changing your mattress should be your first solution. Memory foam mattresses are good at improving initial comfort, allowing your body settle in a healthy comfortable position and stay there all night long.

Sleepers with aches and pains

Memory foam mattresses provide pressure relief which helps alleviate aches and pains. The best memory foam mattress hits a perfect middle ground between softness and support giving support where needed and relieving pressure in key areas susceptible to aches and pains.

Sleepers who run hot

If you run hot at night, a good memory foam mattress might help. Manufacturers have come up with clever ways to assist with heat distribution, but if you sleep very hot a memory foam might be the best to avoid altogether.
