I ordered the sheets when we first got the bed delivered. I already had twin sheets but not XL and the comment in the reviews that made me by them was that they fit so well. That is so important as putting a fitted sheet on any mattress is an ordeal for me and since the two twins are right next to one another, I knew it would be even more important. I was not disappointed. They are fairly easy to put on the mattress and they fit and feel great. I also really like the pale green color and plan to order another set soon.
