### ⭐⭐⭐⭐⭐ Best camping sleep for the money.
*by R***N on September 6, 2024*

The only thing I dislike about this, is that it didn't exist sooner. 😂 Easily the best camping air mattress I've ever used. It felt like sleeping in my own bed, because of the foam, it's great. I slept well, all night, on the ground, in the woods. No tossing and turning, and I felt rested in the morning. It's not loud or makes weird noises when you move around on it, and it feels soft to the touch instead of plastic or something. It will basically self inflate, but the bag it's stored in can be used as a pump, which is neat, but I bought the tiny pump for it. Inflates in under 10 minutes I think. It's a bit bulky, not for backpacking but if your worried about your back and want to camp, use this mattress, my 75yo dad approves. 👍 It seems well built and can support my fat butt so I recon it will yours too, and be comfy. 🥰
