Thickness doesn't always equal comfort. It's not just how tall your mattress might be-it's what's packed inside. With the Beautyrest Black Hybrid Plus Tolliver, you get layers and layers of firm support topped off with just a hint of plush conformability. It's the best of both worlds for back and stomach sleepers who want pressure point relief, spinal support, and contouring memory foam comfort. The Tolliver firm mattress is built from the bottom up and the inside out, starting with multiple layers of advanced innerspring technology. The 850 Density Advanced Pocketed Coilâ„¢ core is accentuated with an inch of 2000 density Contour Support Micro Coil, preventing motion transfer as you settle into bed and relieving pressure points by contouring to your shape. You won't have to worry about your conforming mattress sleeping hot, either-both the core and the comfort layers are infused with AirCoolÂ® and Black HybridICEÂ® cooling properties. The Beautyrest Black Tolliver reviews are in and they're fantastic. But you don't have to take their (or our) word for it-try the Beautyrest Black Hybrid Tolliver for yourself at your local Mattress Firm, or purchase online to take advantage of the 120-night sleep trial and see if it's the right luxury mattress for you.
