I wanted to sleep on this mattress for a few days before submitting my review and let's just say that this mattress does not disappoint! IT'S GREAT!! This mattress is firm, yet VERY soft and COMFORTABLE! With this mattress, you don't have to worry about disturbing anyone who may be sleeping on the mattress with you. It's quiet and does not around. It works well with an adjustable base or a boxspring. I wouldn't recommend using this on top of another mattress. You'll need the support of a base as I mentioned before or boxsprings. I love it so far! Definitely worth purchasing. Also, shipping was a breeze. P. S. - This bed is SUPER HEAVY. Please be sure to place the mattress in the room where you want it BEFORE unwrapping it.
