Ok....I can't say enough praises for this mattress! I ordered this on 11/22 and it was delivered on 11/23 (was that fast or what???). I allowed the mattress to inflated according to the guidelines, which I recommend, and after receiving our Dalessio platform bed, a day later, was able to test it out. So far the last two nights have been the best two nights of sleep that my spouse and I have had in a long time!!! The mattress stays cool and is soft enough, but  with the firmness that we needed. Also, the bed did not seem to have any odor as some have commented. If you want to experience sleeping on a cloud, this is the one!
