Description
The Sealy Chapman Extra Firm Mattress is the most robust option in the Elevate Collection, expertly crafted for sleepers who prefer a firm, supportive sleep surface with uncompromising durability. Designed to deliver long-lasting, personalised support, it provides a solid foundation for restorative sleep night after night.
At the core of the mattress is Sealy’s patented AlignSupport® spring system, a unique two-stage design that senses your body shape as you settle into your preferred sleeping position. Once aligned, the springs deliver deep, consistent support tailored to you. Each spring is twice tempered, making the system exceptionally resilient and proven to perform reliably throughout its lifetime.
Surrounding the spring unit is UniCased® edge support, featuring precision-engineered interlocking keys that secure the springs in place for enhanced stability. This creates a larger, more usable sleep surface, eliminates the “rolling off” feeling, and ensures dependable edge-to-edge support year after year.
Beneath the springs, BasePlank technology provides a unifying foundation with structure from corner to corner. Integrated air channels allow air to circulate freely through the mattress, improving breathability and overall sleep comfort.
Targeted pressure relief comes from ComfortCore®, positioned in the centre third of the mattress to support the hips and lower back. Combined with layers of firm and extra firm foams, the Chapman delivers a strong, robust feel ideal for those who demand extra firmness and stability.
Finished with premium-quality upholstery, the mattress is woven with SmarTex® to help disperse heat away from the skin and regulate temperature. ProShield® technology adds protection against allergens, helping keep the mattress clean and fresh—endorsed by Allergy UK. Handmade in Britain and backed by Sealy’s 7-year guarantee, the Chapman Extra Firm is built with integrity and designed to last.
