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!

Sturdy, low-profile base

Jun 14, 2026
Eric O., Mountain View, CA
I got this because I couldn't find slats wide enough to support my new Tempur-Pedic mattress, and I feel like it was the better choice. The uniform support is great, it's pretty light and feels durable. Very happy with my purchase!
