Sale! Twin mattress, Sealy Cocoon: 38” x 74.5" x 10". Used fifteen times at the most. Also have a twin-sized Sealy box spring which I'd like to sell at the same time. Both are essentially new. There is nothing wrong with these. I had an old bedstead I could not adjust well and they are so thick that it put the top of the mattress about 4 feet off the floor. Review online if you have questions.
