Sealy's Astwick mattress comes from the Advantage collection, offering medium firmness for comfort and body support while you sleep.

The PostureTech springs are precisely-engineered to offer deep-down support, targeting the key areas of your body that need that a bit of extra help when resting. Bespoke and wonderfully bouncy, the springs are twice tempered which means they will never let you down, providing support that is long-lasting. Not only this, EdgeGuard is nestled inside the spring unit to help the mattress keep its shape over time and provide added durability.

Threaded throughout the mattress is soft and silky British Wool, a natural comfort fibre that adapts to your sleep climate. Keeping you cool in the summer and warmer in the winter months, wool is designed to regulate your temperature and ensure a peaceful night’s sleep.

The Astwick is quilted for luxury with contemporary, premium-finish fabric.
