Exped MegaMat 10 Sleeping Pad Review

Exped MegaMat 10 Sleeping Pad Review
The Exped MegaMat 10 is a luxurious full-size self-inflating sleeping pad best suited for car camping at a campsite or inside your car or truck. Available in a one-person or two-person (Duo) size, the MegaMat is 3.9″ thick and has an R-value of 8.1. I picked up the one-person model this spring to outfit my Subaru Crosstrek as a mini-camper because I’m driving all over New Hampshire on a quest to climb the 500 highest mountains in the state. While I try to backpack or basecamp when I’m climbing several peaks near one another, it’s convenient to have a thick air mattress in the back of the car for those times when I’m in the middle of nowhere and the sun starts to set.

Sizing

The Exped MegaMat 10 is 72″ long x 25.6″ wide so you have plenty of space to stretch out at night. The mattress is 3.9″ thick and has vertical sidewalls like a bed, and not tapered like most inflatable or self-inflating camping mattresses. That alone is an impressive feat of engineering on a self-inflating pad. Those vertical sidewalls make it feel like you are sleeping on a real bed, which is the point.

The Exped MegaMat 10 is available in several sizes, which I list here because it can be confusing to dig up this information:

Self-Inflating

The MegaMat 10 is self-inflating, which makes sense when you have a sleeping pad of this size because you’d be at it all day if you had to blow it up from scratch.  It has two flat valves, one for topping off the inflation with a small foot pump that’s included, and a second, larger valve used for rapid deflation.

I don’t find the included foot pump for topping off the pad to be effective.

I’m not a fan of the foot pump because it doesn’t move much air. I just top of the pad by blowing into it a few times. You could also use an Exped-friendly inflation sack like the Exped Schnozzel to top off the pad.

Exped uses flat valves on all of their sleeping ads because they’re so much more durable than stick valves and they don’t require any extra room. I can just fit the MegaMat 10 into the back of my Crosstrek lengthwise with the front seats pushed forward as far as they can go because the valves are flush with the sidewall. If they stuck out like a stick-valve, the pad wouldn’t fit.

In addition to better durability, the flat valves fit into tight places.

Insulation

The MegaMat 10 is insulated with open-cell foam which traps and retains heat and brings the pad’s R-value to 8.1, so it’s warm enough that you can use it year-round, including in winter. Does that make it too warm for use in summer? No, it’s a non-issue. Your bed at home has a high R-value too.

Comfort

What’s the MegaMat 10 like to sleep on? It really feels like a bed because it retains its flatness as you move around on it. It has a soft tricot covering that’s comfortable to lie on but you’ll probably want to sleep in sleep clothes are inside a sleeping bag to keep it clean. I believe you can also buy fitted sheets for the MegaMat 10. What will they think of next?

I sleep incredibly well on the pad when I’m sleeping in my car or in a tent with it, in part due to its width, but also because it provides a moderately firm surface for me to sleep on. It’s completely different from sleeping on a regular backpacking-weight mattress, but then again it’s not trying to be one.

I also find that the MegaMat 10 is the perfect height for sleeping in my Subaru Crosstrek because it’s 3.9 inches high and easily adapts to the unevenness and irregularities of the back of my car when I fold the rear seats down. I’ve tried other inflatable and foam sleeping pads back there and just hated them. The MegaMat 10 makes sleeping in my car something to actually look forward to.

Recommendation

The Exped MegaMat 10 is a self-inflating sleeping bag intended for camping. In addition to comfort, it’s very portable and easily carried, unlike a giant inflatable travel mattress that requires a motorized pump to inflate. I also like the fact that the MegaMat 10 is self-inflating and can be used in a tent or a car/truck. But the bottom line is that I sleep like a baby when I use it, which is all the justification I need.

As a side note: I bought my MegaMat 10 Used from REI at a steep discount. It’s worth checking there if you want to save some money. Summit Hut also has the best selection of Exped products if you want to buy it new.

  1. Hmmm. I have to make sure this will fit in the back of my Outback. Pretty sure it will if it fits in a Crosstrek.

  2. Yeah, but I have a reputation as a measure once-cut twice carpenter, so I’d better make sure!

  3. Will either of the Mega Mats, 78×30 or 25×72 fit the Big Agnes sleeping bag system? Specifically the Echo Park or Diamond Park series? Of course for car camping!
    Thank you

    • I’m pretty sure the BA sleep system can accommodate a 25″ pad, but since I don’t know what model bag you have, your best bet is to go to the BA website and check the specs there.

  4. Thank you!

  5. The megamat sleeps just like a real bed indeed. I use it as a basecamp bed and altough i sleep fine on my Xlite on the go, getting back to the megamat after a while is a real treat. Did not use it for car camping, but you just inpired me. Thanks for that!

  6. I have a 2020 Crosstrek and according to the dimensions I am guessing there will be a space behind the backseat when they are folded down. Do you have pictures taken from the rear door? Don’t you think the head of the mattress will need support since the bed is 7-8 inches longer than the backseat?
