Excellent mattress! I am a petite woman and the box weighed 20 pounds more than I do, but I was able to get it down a set of stairs and out of the box with no problem. The mattress is small in its larval stage but will grow and expand rapidly once it has been freed of its plastic cocoon. Regard the ominous sucking noise as a warning and get out of the way fast- it grows up in a hurry. After the 48 hours needed for the mattress to reach full maturity, it is ready to go! I am in love. It is soft, yet without the unpleasant sinking feeling I’ve come to associate with typical memory foam mattresses. I think the addition of gel was a huge improvement and will be happily sleeping on this mattress for years to come.
