## Description

desertcart.com : Therm-a-Rest MondoKing 3D Self-Inflating Camping Sleeping Pad, Large - 77 x 25 Inches : Sports & Outdoors

Review: Amazing comfort - This is one amazing air mattress. I have never liked sleeping on air mattresses. This one is a game changer. I am 300lbs and it was so comfortable I slept better on this than on my own bed. Five stars. Highly recommend!!!!
Review: Best camping sleep for the money. - 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. 🥰

## Features

- Camp like royalty with the MondoKing 3D, an ultra-comfy 4.25-inch thick sleeping pad with a stretch knit fabric layer for resting better under the stars

### ⭐⭐⭐⭐⭐ Good
*by S***H on July 25, 2025*

Pros- Great for camping. Self inflates with bag of air (please watch a video on how to fill up quickly). Can adjust how much air for firmness, pretty comfy, good quality, good length. Con- toddlers think it’s a trampoline, hard to sleep next to someone as they are meant for one person, even with a second next to them. Does slide a bit on the bottom of a tent.
