My husband and I both sleep comfortably for the most part. It’s advertised as back and stomach sleeping but I’d say it’s more back and side after half the night on my stomach, my lower back is sore. But other than that I’ve had very restful sleeps on this mattress. The edges don’t seem very strong, if you sit right on the edge it does sink pretty low and if you push against the bed while standing the mattress bows in and feels as though the cushion layer and the springs separate. We have a toddler who loves to jump on the bed and when my husband jumped with him the bed bottomed out. So like I said, it’s a very comfortable mattress just not sure it’s longevity, which is unfortunate for the price.
