A memory foam mattress is a mattress that can be either made solely from memory foam, or a mattress that has a top layer of memory foam combined with springs or foam – often known as a hybrid mattress.
The foam used in these mattresses is made from thermodynamic polyurethane which reacts to body heat and was developed by NASA to help reduce the extreme pressure astronauts faced when leaving and entering the Earth’s atmosphere.
Memory foam mattresses provide excellent pressure relief by helping to evenly distribute your body weight over the largest surface area.
Historically Memory Foam mattresses were known to ‘sleep hot’ as they retained heat. If you sleep hot, then look for the latest Memory Foam advancements where the memory foam is mixed with other technologies such as gel to reduce heat build-up. There are also more open cell Memory Foams developed now that dissipate the excess heat more effectively.
Memory foam mattresses are ideal for front, back and side sleepers as they adapt to your individual shape and sleeping position. They are also highly recommended for anyone who suffers from aches and pains as the pressure relief they offer can ease the pains by reducing the pressure especially on the joints.
