It's a great mattress. It turned out to be a smidge to soft for us, but we got a mattress topper to help with that. 
Also, unrolling it so it can inflate is a challenge, because it's rolled in such a way that it ends up upside-down when it's unrolled. It's problematic for us because we have loft ceilings and had a difficult time flipping the mattress over. That's not a complaint. It's just our experience.
Helix has been fantastic to work with and we would highly recommend them!
