Expert Review by Jed

With a firm, yet forgiving overall feel, and some of the highest-end comfort materials Beautyrest has available, the Beatyrest Black Mariela Luxury Firm is a great luxury mattress for those who enjoy a firm level of comfort.

The Mariela uses Surface Cool Plus Fiber in the quilt to help regulate body temperature and wick away moisture. Top-notch comfort padding layers include AirCool Gel Memory Foam and the new Black Ice Memory Foam. These comfort layers are designed to contour to the curves of your body to alleviate pressure points and reduce tossing and turning. AirCool Gel Memory Foam includes gel to provide a more supportive feel, and the Black Ice Memory Foam includes diamond particles and phase change material to pull heat away from the sleeping surface and help keep you thermal neutral. A layer of comfort response latex further enhances pressure relief and is also anti-microbial and anti-dust mite. Back support is provided through the top-of-the-line advanced pocketed coil system. This system is individually wrapped to contour to the curves of your body and reduce motion transfer, and is made from braided cable coils for extra strength. This system is also adjustable base friendly. The 360-degree, 3-inch foam encased edge support system helps ensure consistent comfort all the way to the edge of the mattress.

So if you enjoy a firm feel and are looking for one of the best mattresses Beautyrest has to offer, the Beautyrest Black Mariela Luxury Firm may be just the one for you. This mattress is made well and comes backed by a 10-year warranty.
