Solid base with no motion transfer

Sep 22, 2026
NoMoreMoving, Jacksonville, FL
I’m very happy with our Tempur-Pedic flat bases. We previously had a Serta adjustable base, but it transferred too much movement, so we could feel every time the other person moved. With the Tempur-Pedic flat bases, there is virtually no motion transfer, and the mattress feels properly and consistently supported. We’re also very happy that we chose to stick with authentic Tempur-Pedic products. The bases were incredibly easy to set up—just cut away the wrapping and they’re ready to go. They were also light enough that I was able to move them myself. The king-size base comes as two separate twin bases, which makes it much easier to move and set up. It also works especially well with a split king because the two sides remain independent, with essentially no movement transferring from one side to the other. Overall, we’re very happy with the purchase and would absolutely recommend these bases.

A gamechanger. It is one of those products that delivers exactly what it promises. My sleep has improved to the point of making a difference in m days. It pairs perfectly with my Temper-Pedic Hybrid mattress. The comfort level is outstanding. I highly recommend this base for anyone looking for support that actually works.

Haven't had any issues with the power base frame. Does what it is supposed to do, my only complaint is the legs did loosen over time but not a deal breaker for me. Keep in mind the frame is heavy and could be troublesome for those who can't lift or maneuver it around.
