Simmons Beautyrest Black L-Class Mattress Extra Firm

Sleep is more than a necessity and a mattress should represent something more than utility. Beautyrest Black® is where technology and luxury intertwine to take you far beyond mere comfort. It’s about sleep that indulges the senses. Sleep that refuses to compromise. Sleep that’s so completely restorative and inspiring, it borders on the sacred. Explore the distinctive elements that compose the Beautyrest Black sleep experience. A bed is an intimate choice—and it’s no coincidence that our high performance fabrics play a key part. When combined with our T3 Pocketed Coil Technology and premium memory foams, the luxurious fabrics create a rejuvenating sleep environment that can only be experienced with a Beautyrest Black mattress.
