I bought this bed a couple months ago and have loved it. My partner and I upgraded from a queen bed to a king and have enjoyed the extra room (my dog has appreciated it as well :) This mattress is really quite firm. It was slightly firmer than I like, so I added a thin mattress topper and it has been perfect. The mattress is also very thick. Make sure you get sheets that fit a thicker mattress. I also got Beautyrest box springs with this mattress. We tried putting them on top of our 10" bed frame and it ended up being too tall for us. If you use the box spring and mattress, make sure you have a very very short frame. Overall I am very happy with the mattress and am glad that I finally upgraded to a Beautyrest.
