I have been using this mattress for 1 month now and it’s exactly what I wanted from a memory foam mattress. It is firm yet soft enough to feel comfortable. It will contour to your body and make barely any movement when rolling over, thus not disturbing anyone on the bed. I waited 24hrs to allow for the mattress to inflate as much as it can. I ordered a 12 inch mattress and it is about 11 inches. Based on reviews I’ve read, when ordering a mattress that inflates, it is best to go up a size since it will most likely be one inch less than expected. With that being said, I don’t mind the one inch less and don’t miss it with having needed at least a 10 inch mattress. Still the beginning of using this mattress so I can’t speak on longevity but so far it’s a great mattress for the price.
