When the box arrived, I could not believe that it really contained our queen size mattress. Never the less, when I opened it and saw that it was rolled and vacuumed sealed in a sturdy/heavy-duty plastic, I was still unsure of what I had gotten myself into. I opened and unrolled the plastic and voila! It was almost like magic or time-lapsed photography. In less than thirty second our full-queen mattress was in the middle of the guest room floor. A word of advice, please make sure to open this product in a large space, because once it starts to unfurl, it cannot be reversed. If you are wondering if this is a lightweight, flimsy type of memory foam mattress, etc...it is not! It is actually heavier and better constructed than the more expensive 'brand name' mattress that's in our master bedroom. Needless to say, the Mrs. and I are 100% happy with our purchase.
