L-Class Medium

Starting at

Beautyrest’s top-of-the-line collection, Beautyrest Black, introduces the L-Class Medium mattress and customer’s are now experiencing luxury on an entirely different level.  The L-Class collection feels up to two degrees cooler than the previous generation of Beautyrest Black while also bringing the most advanced sleep technologies used in the industry today.  

Top Layers of Comfort
NEW Black Ice 4.0 technology brings a cooling element to the cover material that reduces heat buildup via a high airlfow SilkAir Fabric Layer.  Beneath the cover find .5″ of Plush Comfort Foam, 1″ Medium Comfort Foam, 1.5″ Energy Foam and .5″ Beautyrest Gel Memory that combine together to provide one of the best pressure relieving and comfort layers found in any mattress industry wide.   

Core Layers of Support
Introducing the first ever T3 Pocketed Coil Technology that sinds together three individiual steel strands into one coil.  The result is a premium pocketed coil that will absorb energy, reduce unnecessary motion, and provide optimal support for an unparalleled sleep experience.  

Our Recommendation
The Beautyrest Black L-Class Medium mattress is a true medium feel that fits a broad variety of sleeping preferences.  The technologies included in this mattress help promote a cooler, pressure relieving sleep surface.  We highly recommend this mattress for back, side and stomach sleeper as well as those that have trouble sleeping hot at night.
