We've been sleeping on this mattress for 2 weeks and we love it!! A few facts that may be helpful to those reading:This mattress puffs up to about 12 and a half inches, not 14. I don't have a problem with that, but if you are trying to create a bed of a certain height, it's good to know.From reading the reviews, I would've thought the "firm" to be hard as a rock. It's not! IT'S ABOUT THE SAME FIRMNESS AS A TEMPURPEDIC CLASSIC, and if you don't know what that feels like, go into any mattress store and try one out.My advice to anyone would be to buy the FIRM option, because firmer matresses last longer. Then you can buy a topper to adjust the softness the way you like it. You can always make a mattress softer, but you can't make it firmer!Also, there was no smell, we slept on it after 4 hours of it being open and it was fully expanded and just fine. It took about a week to arrive. If you're hesitating, I have only one thing to say."Order it Friend! It's probably the best money I ever spent!"
