Zempire Monstamat Twin Air Mattress
The better you both sleep at camp, the more fun you'll have the next day. Wake up recharged with the Zempire Monstamat Twin air mattress; its noise-minimizing surface feels like memory foam.






- 30-denier superstretch ripstop polyester surface molds to the contours of your body, minimizing partner disturbance and creating a more comfortable memory-foam-like surface
- Heavy-duty, 75-denier TPU polyether film-laminated base provides durability; cross-cored foam allows the mat to self-inflate quickly
- Luxurious stretch fabric improves comfort and minimizes noise
- 360° one-way valve allows you to add more air when self-inflating and prevents air from being sucked back in when deflating; it can be set to 3 positions for ease of use
- 3D vertical sidewall construction allows the internal foam to expand fully; this sidewall expansion also reduces surface pressure, creating a comfortable cushioning effect
- Includes carry bag and repair kit

amazing at first, until it starts to leak
Oh, how I loved this camping mat. So comfortable and plush. Until it mysteriously started leaking after a few years. It's too big for me to put into a bathtub to discover where the air might be leaking, and upon very close visual inspection, as well as keeping my ear close and trying to listen for a feel air escaping, it's impossible to figure out. I've read some other reviews about finding many pinhole-sized holes after some years, and I wonder my is experiencing the same. This is a big (and expensive) disappointment. :/
Very difficult to roll up, inconvenient to store
This mat seems to be very comfortable for the hour after we unpacked it to check it out. However, reading the instructions reveals two serious issues. It is very difficult to roll up, they state that it may take several tries (it took me five, and I weigh 190lb). Even after all that it does not want to roll straight. They also say that you should store it unrolled (that is, inflated). This adds an odd element to your household decor. The 35 mm screw valve will work with either the Zempire pump or the Flextail with the N4 nozzle, which should make deflation easier, doing it without these is far too much hassle. However, the recommended storage as inflated is a dealbreaker for me, it’s much too bulky. This is going back.
amazing but holes on third trip
This mattress is so comfortable and nice to sleep on, that is until it leaks. We bought this for our second camp trip that we took end of may. By our third time using it (mid August) there was clearly a leak. Bummed that we spent to much for only to be able to use it twice.
Super comfy
I've had this for a few years and it's super comfortable and easy to set up. My only problem is that I find it really hard to deflate and roll back up.
