It was slightly bigger than expected but I was able to cut it down to the required size easily with ordinary kitchen scissors. It was for a sofa-bed so slightly smaller than a normal double. It is the perfect depth because I can leave it on top of the original mattress and still fold the sofa up. I did have a 2" memory foam mattress for the sofa-bed before but couldn't fold the bed with it on and had to store it separately. The 1" is thick enough to be comfortable on top of the lumpy original mattress.
There is a very strong chemical smell when you first open the wrapping but it arrived on a nice breezy day and I was able to leave it outside in the garden for a couple of hours to air. Very good value for money.
