PostureTech Core Support
Exclusive to Sealy, the PostureTech Core Support spring system works to support the body where you need it the most. The springs gradually get firmer as pressure increases to provide deep down support and pressure relief.

EdgeGuard works alongside the spring unit for added durability and edge-to-edge support.

House dust mites are a key trigger for asthma, hay fever and eczema, as well as many other allergic reactions. That’s why Bugshield technology works to kill all common bed bugs and house dust mites for a clean, fresh and skin-safe sleep surface.

Tested and approved
The Sealy Windermere complies with BS7177: 2008 Source 5 Medium Hazard. If you would like any more information, please get in touch with us at
