I bought this mattress about 8 months ago. After buying a thinner foam mattress for the guest bedroom, I decided to go for the foam mattress in the master bedroom. As with the other foam mattress, it came in a small package that was easy for one person to move into place and expanded to its full shape within one day. It has been very comfortable to sleep on. I often work on my laptop in bed before going to sleep, and the mattress is firm enough for sitting for prolonged periods of time. The thickness is just right. Unlike the thinner one (6"), this one never sinks into the bed frame. I would recommend this mattress for anyone looking for a mattress that is comfortable and will keep its shape for years to come.
