Great Investment

Prat, Mifflinburg
Was not intending to buy this when I purchased mattress. However, once it was demonstrated to me I realized it would help with a lot of my body issues. Great frame for the price. Very comfortable and the very fact that you can use it on your existing bed frame is terrific.

Great Delivery, Greater Mattress

Jun 18, 2026
Tired Blue Collar Mattress Buyer, Burlington, KS
I had a great experience with Tempurpedic. The delivery was easy to schedule online and they came exactly on time. The mattress was easy to put together, and it feels amazing. I love coming home to this mattress after a hard 12 hour shift and I miss it when I’m out of town. My sleep has markedly improved since buying and I will never go back!

Solid Product

This thing has been wonderful. My husband and I were worried that it might be too short but with the ProAdapt being a bit taller of a mattress it actually worked out perfectly!
