Comfort
The top layer of memory foam offers luxurious comfort.
We've created a mattress engineered for optimal sleep. Our engineered support base, along with our unique combination of conical pocket springs and memory foam, allows two people with different sleeping patterns and body types to enjoy the perfect night's sleep - without being interrupted by each other. We've developed a super comfort layer of what we like to call 'Simbatex' to give cool, gentle support.

This 5cm memory foam top layer is deep enough for you to experience the full pressure-relief benefits of memory foam.
The Visco memory foam moulds expertly to your body shape. It's like a mattress tailor made for you. Our perfectly engineered support base has different zones to ensure a perfect night's sleep for all. Our mattress features up to 2,500 unique conical pocket springs. They individually adjust as you sleep, so you wake up with a spring in your step for the whole day.
