With the Lexi, Simmons designed a firm mattress for discerning sleepers. Combining the most luxurious materials in a high-performance package, the Simmons Beautyrest Black Lexi extra firm sleep system supports your spine and gives you the good night’s sleep you’ve been looking for. High Density Firm Purfoam, the firmest foam Simmons produces, gives the Lexi its extremely stable feel. Secured tightly in the quilting layer, the Firm Purfoam creates a firm sleep surface without adding bulk.

You might not hear the terms “high technology” and “mattress” together very often, but Simmons turned to science and engineering to develop Advanced Pocketed Coil Springs. Triple-wrapped, carbon steel springs provide extra strength and conformability, which means improved comfort and durability for you. Because the Lexi’s springs aren’t joined at the top or bottom like they are in typical mattresses, you won’t feel any movement from the other side of the bed, even if someone drops a bowling ball beside you. While mattress springs are an important part of your sleep experience, you need equally high-performance mattress padding and fabric to make a real difference. The Simmons Beautyrest Black line uses a combination of Energyfoam and Memory Foam to support your frame while you sleep. Topped off with a silky smooth circular knit with modal yarn, the Lexi is as comfortable uncovered as it is with your favorite 1000-thread count sheets. And it’s hard to say what’s better news -- that you don’t have to flip the mattress on a regimented schedule or that the warranty lasts 20 years. Simmons delivers a firm mattress wrapped in luxury with the Beautyrest Black Lexi.
