Getting restful sleep is imperative to increasing your productivity during the day and the Serta Roslyn Hybrid firm California king mattress, made exclusively for RC Willey, will have you sleeping as soundly as your third baby in the middle of after school chaos. No need for achy backs and night sweats, the Roslyn has both cooling foams and a specialized lumbar latex to help you feel cool, relaxed and supported. So don't waste another night tossing and turning - get your new mattress from RC Willey, today!

The Roslyn hybrid mattress is a quilted hybrid innerspring mattress made exclusively for RC Willey. It combines premium latex foam, memory foam, high density polytex foam and a superior coil system to create a luxurious feel with unmatched durability. It is topped with antimicrobial cushion fiber to add comfort, pressure relief and a safe treatment that kills microorganisms and inhibits their growth.

The premium highly durable Carbon Fiber-enhanced memory foam gives a super breathable heat-removing surface to disperse heat out and away keeping you cool throughout the night while the AirFloat FX memory foam provides an anti gravity, buoyant feel, similar to latex, with a high level of durability. The unique properties of this responsive foam help to relieve pressure from the heavier parts of the body like the head, shoulders and hips. Its open cell structure provides a high level of breathability, helping to dissipate heat and moisture from the body for a more comfortable sleeping temperature.

The middle center zoned Lumbar Latex is extremely durable and is placed in the center 1/3 of the mattress to create a counter balance to a person’s heavier torso area to improve proper spinal alignment.

Don't forget the mattress pad! When purchased at the same time as a mattress from RC Willey, our high-quality mattress pads help keep your mattress safe with a 10-year limited guarantee.
