Sealy Blake

The Sealy Blake Mattress delivers the ideal balance of comfort and support with a medium feel that suits a wide range of sleepers. Not too firm and not too soft, it’s a true crowd-pleaser designed for restful, supported sleep night after night.

At its core is Sealy’s patented AlignSupport® spring system, engineered with unique coil geometry that senses your body as you lie down. It provides an immediate, responsive comfort on contact, followed by deep, consistent support at the heart of each spring to evenly distribute body weight. Each spring is twice tempered for dependable performance and long-lasting durability.

The mattress is finished with UniCased® edge support, surrounding the entire perimeter to create a larger, more usable sleep surface while eliminating the “rolling off” sensation and maintaining stability across the mattress’s lifetime.

For a solid foundation, BasePlank technology sits beneath the spring unit, offering corner-to-corner structure and stability while allowing air to flow freely through integrated air channels for enhanced breathability.

Sealy’s signature Posturepedic ComfortCore™, positioned in the centre third of the mattress, targets the hips and lower back—where pressure relief matters most. Combined with a blend of Sealy Medium and Firm foams, the Blake delivers a refined, cocooning comfort that supports your posture without compromising on relaxation.

To complete the experience, premium fabrics enhance both comfort and style. SmarTex® technology helps disperse heat away from the skin to regulate temperature, while ProShield® offers built-in allergen protection for a cleaner, fresher sleep surface—endorsed by Allergy UK.
