Bought this for kids sleepovers and for when guests take my kid's bed. My kids have foam mattresses on their normal beds so this made for an easy transition/ good sleep even though they're on the ground. At only 4" thick, I wouldn't use this for a large teen or adult but it's great for my purposes. I took one star off because it's still rather large when folded/ in its carrier so it does take up some prime real estate in the car when going on trips (or, so I imagine. We plan to try it out in 2 months), but overall I'm glad I bought it
