Who would have thought, A compressed mattress in a box. 
This is a queen sized unit and it weights enough to use caution when moving.
After waiting 3 days for it to take shape and form it turns out that it is better than I thought it would be. Keep in mind that this is ONLY a one sided mattress. Time will tell if it is a good mattress or not. 
It has a very nice firm and soft feel to it.
