Mammoth's unique medical grade foam is a revolution in sleeping technology.

This foam promotes deep healing sleep, and has been endorsed by the Chiropractic Patients Association, the Department of Health, and the National Institue for Clinical Excellence.

Ideal for athletes and sportspeople, the Mammoth range has been specifically designed to offer the perfect conditions for muscule and joint recovery after exercise.

Medical grade foam has been used in hospitals and clinics for years to give patients the best conditions for healing during sleep - the Mammoth range brings this technology to your home, where you can benefit by getting the best sleep whether you have a chronic condition, or you simply want to get the best night's sleep possible!

Unlike memory foam, the high specification medical grade foam is not heat reactive, meaning it reacts the same whether the sleeping environment is warm or cool. It also does not trap heat in the same way that memory foam can, meaning that these mattresses allow you to sleep in a cool, comfortable position.

Featuring a 10 year Mammoth guarantee, the Performance 220 is hypoallergenic, and features a cooling cover and integrated mattress protector.

The Performance 220 is a 20cm deep mattress.
