What is a memory foam mattress?

A memory foam mattress - also known as a memory mattress or foam mattress - is a mattress with a layer of viscoelastic (memory foam) on top.

Memory foam mattresses are remarkably comfortable, provide high levels of pressure relief and are naturally hypoallergenic. They're temperature-sensitive and contour to your unique shape, giving you extra care for aches and pains.

They also feel luxurious - so they're the perfect way to relax after a long day.

Select a softer or medium memory foam mattress for a super-comfy feel, or if you sleep on your side. Prefer extra support? Try a firmer memory mattress instead.

You should also consider mattress size. If you're shopping for your children or a guest bedroom, a single memory foam mattress is best. A double or king size is a perfect choice for couples. For a luxury memory foam mattress feel - try a superking!
