I’ve been really happy with this mattress. It’s comfortable and really versatile. The tri-fold design and handle makes it easy to use in various places. We’ve used it for camping, traveling and even as a guest bed. It has about 4 inches of foam with three different layers. The last layer,the gel, feels incredible, like it’s a twin mattress. It feels like a nice medium-firm comfort. It’s supportive but still soft to sleep on comfortably. I also like that the cover feels nice and breathable, and it has mesh sides which seem to help with airflow. I especially like the co er because it’s washable! When we’re not using it, I just fold it up and slide it under the bed, so it doesn’t take up much space.

It feels sturdy and well-made, perfect for everyday use. One of my favorite things is how incredibly soft it is—honestly, it feels like cotton! It’s so comfortable that it makes sleeping or resting on it really enjoyable. It also has a nice size and provides great support whether you’re sitting or laying down. Overall, I’m very happy with this purchase. Highly recommend it to anyone looking for comfort and quality

I purchased this 3-Inch Twin XL Trifold Mattress as an extra sleeping option for guests, and it has been very useful. The memory foam feels supportive yet comfortable it doesn’t feel like you’re sleeping directly on the floor. It works especially well as a temporary bed or for RV use. I really like the three fold design because it makes storage simple. It doesn’t take up much space and fits easily in a closet. The removable, washable cover is a big plus for keeping it clean. The non slip bottom also helps keep it in place on hard floors. It’s not a replacement for a thick traditional mattress, but for guests, travel, camping, or small spaces, it’s a very practical and comfortable option.

I bought this folding mattress to have an extra sleeping option for guests, and it has been a great purchase. Even though it’s 4 inches thick, the memory foam is quite comfortable and provides good support for a night’s sleep. I love that it folds easily, doesn’t take up much space, and is very practical to store or take on the go—perfect for camping or using in an RV. The cover is soft, removable, and washable, which is a big plus, and the non-slip design helps keep it in place. Overall, it’s a comfortable, functional, and very versatile option. Perfect as a guest bed or for occasional use.

I’m really happy with this mattress. It’s very comfortable and provides good support without feeling too firm. The XL size is perfect and gives enough space to sleep comfortably. The material feels durable and well made, and it expanded nicely after opening. It was also easy to set up and didn’t have a strong smell. I’ve been using it for a few days now and it holds its shape well. Great option for guests or everyday use. Definitely worth the price!

The materials look and feel like really solid quality even though it definitely gives off a 70s RV look with those velour handles. I have another 5 inch mat that bottoms out immediately when you sit on it but this one actually resists adult body weight. The plop test is great because the high density foam inside is sturdy enough that it actually feels thicker than 5 inches. It does not have that cheap squishy feel that a lot of portable mattresses have. You can kind of feel the seams where the sections fold together but it is not a deal breaker. If you put a thick enough blanket under you then you do not really notice the gaps at all. The non slip backing is good for floor surfaces and our guests honestly prefer sleeping on this over the futon couch we got from Walmart. Portability is where you have to be realistic because this thing is not small. I tried to fit it in my Prius hatchback trunk but since I already had some gear back there it just would not fit. I had to put it in the back seat instead, and it basically took up the entire space. It is fine for a solo trip, but if you have a full car of people and gear you are going to struggle to find a spot for it. Shipping was kind of silly because it came in a tall box that was shoved inside an even larger Amazon box which meant the heavy box was just sliding around in the bigger box. The instructions tell you to wait a few days for it to fully expand but mine puffed up to size almost immediately right out of the bag. Just a heads up it comes tightly vacuum sealed so release the air slowly or it will literally fly open on you, and always cut the plastic carefully so you do not slice your new mattress.
