This is good value for the money. I got the extra soft kinda 8 inch thick. I'm 5-6 and 175 lbs. It works just fine and is comfortable. I had a $700 memory foam mattress a few years ago that was too firm it was awful I ended up throwing it out after a few months. This one is great, soft, and comfortable but still provides good support. I fee like my body is getting a better supportive sleep while still being comfortable.
The mattress came in an oversized drawstring bag with the mattress inside all rolled up in a sealed plastic bag - it was quite fascinating to open it up and watch it "become" a mattress! When I first laid on it I thought it was going to be way too soft, but after the day went by and I laid on it at night, it was much firmer . . . . and VERY comfortable!! It has been a pleasure to sleep on every night!!
