I was reluctant to purchase a mattress online because I've always tested out options in store. The reviews were very helpful but ultimately what convinced me was the double sided use. I do prefer the softer white side of the mattress and can see the benefit of switching to the firmer side after years of use. After a week on the mattress I am SO glad I made the purchase. Worth every penny!. Jill. Napa, CA. Fri Sep 25 2026

I bought this because my mattress needed to be a little higher to be even with my nightstands. I live alone, and it looked like I might be able to deal with these folding foundations on my own. The box they were delivered in was a bit heavy and awkward to get into the house (I wish all large boxes had handles punched into them), but once I did, it was easy enough to maneuver the foundations into place under my existing mattress. Another plus is that they lift the mattress above a one inch lip around the bed's platform, making it quite a bit easier to put clean sheets on. So far, they don't make any noise and solved all the problems I was hoping to solve.. Elaine. Cincinnati, OH. Thu Sep 03 2026
