Enjoy endless possibilities for restful sleep with this mattress and adjustable base set. The firm mattress, which features hyper-cool technology, offers the best of both worlds: a hybrid innerspring mattress with the pressure relief of cooling gel-infused foam, coupled with body contouring pocketed coils for superior support. With the touch of a button, the power base smoothly raises your upper body to relieve pressure points, sit up in bed or sleep in a partially inclined position (helpful for people who snore or experience acid reflux). Convenient USB charging is available for powering up your devices.
