MLILY King Trifold Mattress, 4 Inch Foldable Gel Memory Foam Mattress

I got this Japanese foldable futon for my younger sister last year during Thanksgiving or for her Christmas gift. She had mentioned that it’s high quality and I got her color gray. It’s worth your value for sure. She mentioned it’s very comfortable and soft it’s rollable and compact size is easily to store away or in the closet or under your bed. You can use it as a guest bed mattress.

I bought this memory foam foldable mattress for my boys to use for living room campouts, traveling, and as an extra bed when we’re camping. It’s been such a great addition! The quality is excellent, and it has the perfect amount of cushioning — comfortable without being too soft. I also love how easily it folds up for storage, which makes it super convenient when we’re not using it. The zippered cover is a huge bonus for easy washing, and we usually add a sheet on top for extra protection and comfort. It’s versatile, comfortable, and perfect for kids, guests, or camping. Definitely a great purchase!

So glad I read the reviews! This is an incredible mattress for the price point. My one year old daughter has slept great on it and I am very comfortable when I lay on it with her (with a memory foam pillow). Highly recommend!! Oh and it fold for easy travel and storage too. Game changer! We put a cotton fitted sheet on it for comfort and cleanliness and it works great. I plan to recommend it to other mommas who have highly sensitive babies who need to roll away during nap time or overnight!

I use this for a "couch" and unfold periodically to sit on. I do wish they individual pieces were detachable, but the soft cover zippers only around all of them together, though you could hypothetically unzip just one piece of foam, leaving the foam inside exposed and the other two together. Really though, it's a very nice, good for the price "bed". The 4in is slightly thin, depending on how or on what you're sitting on, but generally I find it pretty comfortable. The cover that comes with is soft, and removable so it could be cleaned. It's about as large as it seems, though it's not VERY heavy, so if you can put it in the bag (which does come with!) it's fairly portable too. I can't speak to how it holds up storage wise, but I imagine it would be fine. Overall a great product, with some minor drawbacks depending on your use.

I have now ordered 4 of these over the past few months. We are using these for extra beds for when the kids visit us. These mattress work out so well for my grandchildren sleepovers at my ‘up north’ cottage. We set up the mattresses on the floor, with a sheet and a few blankets and they are good to go. The grandkids, ages 5-9, tell me they are very comfortable and they think it’s a fun bed. More importantly to me, they are warmer on the floor than they were with the blow up air mattresses. Our place is on a slab foundation and the house is in Wisconsin, so think cold floors about 8 months out of the year, and we have the kids up all during the year. When the mattress arrives, it is compressed greatly. Before the first time you use it, you have to unroll it and leave it sit out for a few hours, or overnight even better. Once they have expanded to their full size, they are a trifold mattresss. The mattress is covered by a gray removable, washable thicker cover. We obtained some sheets (not included) that fit these and store the sheet in the storage bag with the mattress. It makes for an efficient bed they can set up easily. To store the mattress, it can place the folded mattress in the provided heavy fabric bag. The case has a handle for maneuvering the mattress more easily. The mattress does take up more room than a deflated air mattress, but we just tuck them along the wall in one of the larger guest bedrooms until we need to use them again. They just look like big black squares in the storage bags. I am happy with these mattresses for use for the grandkids. I personally have not tried to sleep on one, and I imagine it’s better than sleeping on the floor, but given the choice, honestly, my old adult body would always choose a bed instead. They labeled these as mattress toppers as well, and I think they would be pretty substantial toppers, raising the mattress 4 inches, but I think they would certainly work for that and increase the softness of a bed as well.

This Twin Trifold Mattress is super convenient and comfortable! I love that it folds easily for storage and is perfect for guests, sleepovers, or travel.

Decent quality of stitching and surface. Foam is thick and comfortable for a short rest. However, this pad is not conducive for an overnight sleep on floor. I had back pain from an old memory foam bed mattress and found that sleeping in floor on a few covers alleviated my pain. This was purchased to increase the padding between my body and the floor, especially for side sleep. However, you just sink in and will be in an unaligned spinal position for however long you sleep. Maybe this would be better as a short term extra bed, or for folks without back pain, but it wasn't comfortable for my floor sleeping.

Very comfortable. Nice thickness. Firm but not too firm. Fits perfectly on sofa once sofa pillows were removed. Came with a very nice storage cover for easy storage. Highly recommend!

No se ve como en las fotos para poder ponerlo como sillón se sentiría muy frágil pero como su función de colchón si es suficiente cómodo para poder dormir, lo puse en una base plegable queen y quedó perfecto

This trifold mattress was bought on 18th Aug 2026. Let me say this is a life saver to me! Good packaging by the manufacturer. Comes with a black zip cover as well! I opened and slept on it the same day. It took couple of days to be completely expand but honestly sleeping on it on the same day I opened is not that of a difference. The cushion inside is incredible. No back pain so far. Apt for both back and side sleepers . Worth the money and affordable mainly for those moving out or starting life (iykyk)! You can place the fold which is open on top where you place your head , tbh it doesn’t matter if you think that it’s gonna slide , it doesn’t . It’s stitched well that it don’t move between the folds . Hope that makes sense !

Good quality of the filling but average of the cover

I like the size, compact packaging, and the bag that came with it. Reasonably priced as well. Glad I got it. Attaching pictures.

Great for compactability and storage but could have been a little thicker. I put my exercise mat underneath it to protect my guest from feeling the bars of the foldable bed frame.
