I was really surprised when this matress arrived because it was rolled up and didn't look as thick as it was supposed to be. Once it was open though and put on my box spring, WOW it blew up! I have always liked a medium matress and my hubby likes firm. I decided after researching quite a bit that a firm memory foam matress was the way to go since I have learned that they will actually soften a LITTLE over time. It took a couple of weeks to get used to (I've always had spring matresses) but we are BOTH sleeping great! I would definately advise the Protect-A-Bed Full Waterproof Mattress Protector with this product but also with ANY matress you want to purchase so that any fluids that my accidently be spilt won't seep into the matress. Also be sure to pay attention to the thickness reguarding sheets. The Luxury Manor 800 Thread Count Cotton Sheet Set fits this bed perfectly!! I read other comments about the smell issue. I was really concerned about this because I have a sensitive nose and stomach. I didn't have any problem with this. The smell was gone within a couple of hours.
