Tredwell Extra Firm

Tredwell Extra Firm is the firmest feel in the Elevate Ultra Collection. Designed to deliver a grounded sleep experience, Tredwell combines smart sleep technology with tailored comfort layers to deliver deep, consistent support that adapts to you. Every element is designed to work in harmony, helping the mattress respond precisely to your body’s needs for a more restorative night’s sleep. AlignSupport® is a sense and response spring system, working in two stages. It starts by sensing your shape as you find your comfortable sleeping position. The springs then respond with deep down, consistent support that you can count on night after night. The entire spring system is also twice tempered, so you can rest easy knowing that your mattress is resilient and built to last day in, day out and throughout its lifetime.
