Just like the post says it’s a trifold and folds up very neatly to put in the closet. I was saving it for my grandson who’s growing out of the loveseat and had it stored in my closet. My husband had a fall in surgery and we had to get a hospital bid for a while. We ended up putting this mattress on top of the hospital bed mattress and giving him comfort that he  KNEW,  was  MISSING !  Great price. This is a buy recommendation. It is way better than the blowup mattresses, even if they are deluxe.  !!
