Review: Thick and comfy, a bit too warm but good price - I bought this hoping it would soften my new split adjustable bed. My husband loves the bed, but it’s way too firm for me. While this doesn’t cool as I would like, I tend to be super hot so it’s probably fine for most people. The price is good, the quality nicer than expected, and it fits perfectly. It does add about an extra almost inch compared to my husband’s side, and I can tell it’s softer than without anything. Stays in place well. I’ll still probably buy a topper to make my side extra soft, but will keep this as well. It doesn’t move around and sheets fit better with it in place.
Review: Nice! - Very nice mattress topper. My son said the bed is much more comfortable now.
