Product Information

The Sealy Alder Geltex mattress combines a supportive spring system and luxurious Geltex filling that will cradle and support your body whilst you drift off into a deep sleep.

This mattress has a 620 Posturetech Spring System which is designed to provide a softer feel that gradually gets firmer as pressure increases without compromising on comfort. The springs are twice tempered, which provides greater resilience and extends the life of your mattress even more.

Geltex® is a unique patented gel infused foam that is quite simple the most advance material on the market. It provides a “push back” body support for a soft yet supportive feel, with an open cell structure that allows for greater breathability for each individual sleeper. Your body temperature will dissipate quickly and effectively for a more constant temperature.

The zonal technology used to manufacture this mattress correctly supports and aligns the spine in its natural shape, helping to reduce aches and pains. Sealy Posturepedic are the only sleep systems endorsed by the world renowned Orthopedic Advisory Board.
