Portable, comfy, and super sturdy
I LOVE THIS! I bought this trifold mattress for guests and occasional use, and it’s honestly become one of my favorite things. It unfolds smoothly, lays completely flat, and the foam is firm enough to support you but still comfortable to sleep on. When it’s folded, it’s super easy to move and doesn’t take up much space. The cover is easy to clean, and it doesn’t lose its shape after sleeping on it multiple nights. Great for guests, kids’ sleepovers, or even stretching and lounging. Definitely worth it.

Good trifold foldout
Color: White, Size: S06-Single
Great as an emergency pullout. Very comfortable, easy to setup and carry with the handles. Good as extra support as an exercise cushion too. Mattress is a little hard but better than being too soft. Fabric could be softer or thicker, but not too bad quality. May be good for a child's nap time. Fits good in closet for storing or accent ottoman in room.

DO NOT BUY.
Update: Amazon refunded me the price of the mattress as I can’t really send it back now that it isn’t compressed and we do not live anywhere near a UPS store. I reached out to the seller as it is listed as having a 5 year warranty. The seller has so far only initially offered me a 10% refund, so not honoring their warranty at all. I have refused this and asked for either a full replacement or a replacement section for the one that is defective. We will see if they stand by their warranty! The package came SO compressed that one of the foam inserts never recovered. We opened it according to instructions, let it sit for 72 hours, and edges of foam were all so stuck together they did not rise properly. I had to take every piece out of both covers, manually pull apart the edges, and then let it rise again. We tried everything to get the third insert to be like the others- put it in a warm environment, put it in the bathroom where there is some more damp air, and still isn’t like the other two. It feels different as well- softer than the other two pieces. It’s like it is a totally different foam. It doesn’t fill out the cover completely and it is consequently very uncomfortable and not useable as one whole section is softer and thinner than the rest. I would like to return it but not sure how now that it is not compressed. Would not buy this product again. Very frustrating.

Firm but not hard
Color: Grey, Size: 4inch-Tw"
I sleep on this on the floor about 50% of the time because it’s so much more comfortable than my actual mattress. It doesn’t leave me with back or hip pain, it doesn’t sink so you never feel the ground like with an air mattress. It folds up to store under my real bed or I can fold in into a chair if I need. I did have to use a hair dryer to fluff up a few of the corners because they were taking a long time after opening but that’s to be expected.
