Sealy Sleep Select Extra Firm Luxe King Size Mattress

Firm doesn't have to mean hard.

Extra-firm support with a EuroTop of 1,000 Micro Pockets, so you get a solid, level base without the hard, unforgiving surface of a cheap firm mattress.

Size: King Size (150cm x 200cm)
Firmness: Extra Firm, 9/10
Best for: Back sleepers, heavier builds and anyone who wants a solid, no-sink surface.

Why it's good for your back

• Rock-solid base, refined top. PostureTech 2.0 and a dense OptiForm Extra Firm layer keep you on top of the mattress, not in it. 1,000 Micro Pockets take the edge off pressure points.
• Keeps the spine level. Weight is spread evenly across the coil system, so heavier areas like hips don't drop out of line.
• Every inch usable. DualEdge reinforces both sides. Sit on the edge to put your socks on, or sleep right to the edge, without roll-off.
• Built to stay firm. Higher-gauge, twice-tempered wire and EternityFibre resist the sagging and dipping that undermines support over time.

PostureTech® 2.0: deep-down support that springs back

A higher-gauge wire and re-engineered head design give a steadier, more stable base. The coil's unique geometry responds to your shape and spreads your weight evenly, so hips and shoulders are supported rather than left to sink. Twice tempered and tested by Sealy scientists.
