The best mattress we have ever slept on!!  I was really apprehensive reading the reviews and knowing that I didn’t get to try it out first and the fact that it came in a small box!!  But when we got it and opened the clear package and it immediately took full shape and was so super comfortable right from the get go without waiting the full 24 hours for full expansion I knew we had made the right choice. It has helped with my back pain and I am sleeping so much more soundly. Amazing what a good mattress can do for you!  I highly recommend this!!  It is soft but firm in the places you need...perfect for people with back problems since it gives such great support. Shipping was super fast!
