So.. this mattress came in a box about 30" X 48". After removing the bed from the box, I was very disappointed by its look of quality, but then I slept on it. This is the first time I woke up without excruciating back pain, and my hips don't even ache. My mother is sleeping in it now to give it a test drive. This is my 3rd bed in 12 months, the other two were very expensive, obviously this one was not. I did previously buy a 2 inch memory foam topper and used that on the bed too. I used one on my last bed too, so that is not the difference. I love that it is only 8", I had to use a stool on my last 2 beds to get onto the mattress. I am not recommending this to a friend, I am recommending this to my mother!
