Comfort

The Antigua has 3cm of high density memory foam, which offers excellent pressure relief, with anti-microbial hypoallergenic protection.
Support
The Antigua mattress provides support in the form of a foam block. Foam makes an excellent alternative to springs, but you have to get used to the idea that you don't bounce on it!
