It took me sometime to narrow down to this mattress. It was a great choice! Know what kind of mattress you want. Visit a mattress store to have an idea of what you need. Don’t buy in a hurry, do your research first. I wanted something not too soft or too firm. This was right. Great back support so far for me. Amazing how something so  compressed in a box bounces up full. I followed instructions on pack. Allow time as instructed to fully inflate to the designed size. Arrived intact and on time.
