The Simmons Beautyrest World Class Level Three Plush Mattress brings together premium triple-strand coil support, advanced cooling foams, and sustainable luxury fabric in a plush 14.75-inch hybrid build.
Cloudy Mattress is an Authorized Simmons Beautyrest retailer, so every purchase is backed by the full manufacturer's warranty. The feel sits on the plush side of the comfort scale, delivering the cushioned cradling that side and back sleepers often seek.
Because of this cushioned response, it ranks among the best 15-inch plush mattresses for side sleepers, offering options for pressure relief at the hips and shoulders.
Inside, multiple engineered components work together, starting with an InfiniCool Lux cooling cover that delivers cool-to-the-touch surface comfort.
This Beautyrest Harmony Lux Diamond Plush uses InfiniCool Lux cooling technology with two layers of active cooling, helping you fall asleep faster on warm nights. Furthermore, the cover features Seaqual Sustainable Fabric, transforming recovered ocean plastics into high-quality upcycled fibers for an eco-friendly, sustainable sleep surface.
Beneath the cooling cover, Micro Diamond Memory Foam is infused with actual diamond particles engineered to conduct heat away from the body. This premium foam layer pairs with SurfaceTouch Gel Memory Foam at the quilted surface for targeted lumbar pressure relief from the moment you lie down.
Additional plush comfort foams cradle the body, delivering cloud-like luxury comfort ideal for side sleepers who need extra cushioning. The mattress also features Beautyrest's premium T3 Pocketed Coil Technology, the brand's premier triple-strand coil support design.
This premium coil system delivers Beautyrest's highest level of individualized support and helps keep the spine in healthy alignment under the plush surface. Furthermore, the pocketed construction provides zero motion transfer for couples, making this an excellent luxury soft pocketed coil mattress for sharing the bed.
RightTemp Memory Foam with highly conductive carbon fibers adds a consistent, supportive feel and additional cooling beneath the comfort layers. A high-density base foam anchors the build, delivering edge-to-edge stability and a lasting restorative deep sleep experience for years to come.
At a generous 14.75-inch profile, this 14.75 inch soft luxury mattress is fully adjustable-base compatible and pairs beautifully with modern foundations.
Additionally, the mattress is made in the USA, built with non-toxic certified sleep materials, and backed by a 10-year limited manufacturer warranty.
Financing through Affirm is also available at checkout for added flexibility.
