      I bought this mattress for my son, and he loves it. I was shocked to see how thick it is! When they say it's 12 inches, they aren't kidding! I tested the mattress out, and it's pretty comfy. He has definitely slept better since we bought it. This type of foam mattress does require a completely waterproof mattress pad, as the foam will soak up sweat or spills. The only *slight* issue we had with the mattress is that it changed the look of the bed because it's so thick. The bed has a footboard and headboard, and it's so thick that it comes just a few inches below the footboard.

      This mattress is made by Sleep Innovations. Not sure where the connection to Serta is made, maybe it's a subsidiary? It's an overall nice mattress, a bit on the firm side. Good quality for the price.

      Verified Purchase

      Unfortunately the mattress was slightly bigger then our box spring but overstock was willing to exchange or give us a partial credit. We decided we could live with the mattress and avoid the whole return process.

      bought this as a guest bed for the holidays. My brother slept on it during Thanksgiving and my father who has a bad back slept on it for a week and they both said it slept great. This is the reason why we bought this in a king for my husband and I.

      Very comfortable mattress! Molds to the body, but is not too soft.

    • This is the second Foam Mattress we've bought!
      Verified Purchase

      We love this mattress. Bought it for our daughter's new studio apartment. It is firm and comfortable providing a restful night's sleep. We are considering replacing our traditional queen size mattress set with this memory foam mattress. We feel it is the same quality as the brands sold at local Mattress Stores but at at 80% less than their cost!
