The most comfortable mattress style available is the pillow-top, and Simmons adds extreme luxury with high performance materials in the Beautyrest Black line. The Mariela Plush Super Pillowtop features a cushy pillowtop that gives you extra conformability, so it feels like the mattress is embracing you while you sleep. Under the soft, modal yarn finish, Simmons includes layers of high tech foam. The NxG memory foam provides a pressure-free night by molding comfortably to your body, and it helps dissipate heat. But they don’t stop at just one layer. While one layer covers the springs, another layer of NxG memory foam is attached directly to the quilted top, a feature that no other mattress manufacturer offers. You lay directly on memory foam, so you get all the benefits as the foam conforms to your body. Simmons also makes sure the foams in the Mariela offer just the right resistance level by using a process they call Transflexion. They work the foams to break them in before you take them home, so you know that the mattress you sleep on the first night will feel the same a few years down the road.

In addition, the Beautyrest Black Mariela contains Simmons’ Advanced Pocket Coil springs. Each of the extra-strong carbon steel springs is isolated in its own pocket. That separation between the coils means that movement on each area of the bed is also kept separate, so if you’re sleeping next to a flip-flopper, you won’t get bounced around. The Simmons Black mattress collection is designed with luxury in mind, so the materials and fabrics are all of the highest quality. A 20-year warranty guarantees the Mariela’s performance long into the future, and a no-flip design makes it easy to maintain.
