Luxuriously Firm Feeling of Comfort
by Jed HarringtonThe Beautyrest Black L Class Medium mattress is a perfect choice if you like a firm but not hard level of comfort and want something that feels luxurious.
Firm Yet Lofty Overall Feel
Firm but not hard, the L Class Medium will conform to the lower back without having an enveloping, sinking feeling. We assigned it a Comfort Scale score of 3.5 out of 10 (with 1 being the firmest) because of its ability to gently cushion the hips and shoulders but offer a solid underlying feel.
Among the Top Support Systems On the MarketThe T3 Pocketed Coil System provides top-tier support through a three-piece braided coil constructed using high carbon steel.
Quality Temperature ControlBlackICE 4.0 is a high grade four-stage cooling system that consists of four components working together to keep you cooler.
Features Beautyrest Gel Memory FoamThis foam enhances conformability and pressure relief to improve deep REM sleep and ensure reduced motion transfer.
Prefer Firm Comfort? You'll Love This.If you want a firm level of comfort, but not one that feels like sleeping on the living room floor, the L Class Medium will make a suitable choice for your sleeping style.
