The TEMPUR-ProBreeze Medium Hybrid we recently bought is the best mattress we've ever owned. It replaced our old Tempurpedic mattress that was beginning to soften after 13 years of good sleep. I was having more difficulty changing position in the old mattress because it was getting softer, but the TEMPUR-ProBreeze Medium Hybrid's coil layer provides the right amount of pushback to help me get out of bed easily after a great night's sleep. We also bought an ERGO base to go with the new mattress, and the result is that we sleep better than ever before. The investment in our new bed has been worth every penny.
