The TEMPUR-ProAdapt® Medium Hybrid mattress is a first of its kind hybrid mattress. This is the first hybrid to contain the all new TEMPUR-APR® material. The material boasts Advanced Pressure Relief from its famous Original Material and is the first time the "secret sauce" was reformulated to be even better! A culmination of continuous research and innovation, this mattress provides comfort and support unlike most mattresses. The 1000+ premium spring coils were designed to interact and compliment the TEMPUR® Material Comfort and Support Layers. Receive the benefits from both worlds; the best conforming surface adjusting to your body plus the buoyancy the premium spring unit provides. Your body rests on the Smart Climate® Dual Cover System featuring a zip-off, washable cover. Underneath the cover you will find a super stretch inner panel, that constantly draws heat from above, maintain a cool surface. You want life changing sleep and this mattress will do that!
