As a long time Tempur-pedic owner, it was time to replace our mattress, so we purchased a new mattress and the power base after trying it out in the store. What a difference, the powerbase makes in comfort in bed. The immediate relief felt in the lower back, you don\u2019t even realize the stress is there until it goes away. Highly recommend these! My first nights Sleep was better than my last night on my previous Tempur-pedic. We are very, very pleased with the purchase. I\u2019m looking forward to spending more time using the music, massage and the sleep tracking features to both relax, fall asleep and just overall enjoy the wind down experience even more!
