It is filled with virgin Vitafoam, which is our secret combination of flexible polyurethane sponge foam of medium and high density. Namely the same sponge foam that is found in high end couches and mattresses. 

Our special foam not only delivers yielding comfort and plush support but excellent bounce-back and longevity far beyond ALL normal foams.

Our foam filling expands around your body to support you when you're relaxing and returns to its original shape when you get off. It generally has a 5-15 year life span depending on the 'out-of-normal' and intensity of its use. Thereafter it can simply be topped up with additional foam from our factory.
