Rating and Summary

The Exped MegaMat Duo 10 Sleeping Pad is super comfortable; it’s plush, soft, flat, quiet and bouncing is super minimal. In fact, it’s my most comfortable camping mattress for couples.

And that’s not all. I also found the Exped MegaMat Duo 10 to be super warm, very easy to use, and extremely high quality.

However, it’s biggest downside is that it’s quite expensive. Would I still recommend it though? Read on to find out!

Testing and Performance

I put the Exped MegaMat Duo 10 (Medium Double) through these 5 tests:

  1. Comfort
  2. Ease of Use
  3. Portability
  4. Versatility + Sizing
  5. Quality

Here’s how the Exped MegaMat Duo 10 performed.

Comfort

Thickness and Loft

The Exped MegaMat Duo 10 gets me 4 inches off the ground. When inflated to my personal preference, which is a little bit softer, my body does not touch the ground whether I’m sleeping on my back, stomach, or side.

This is a picture of me lying down on my side on the Exped MegaMat Duo 10.
This is a picture of me lying down on my side on the Exped MegaMat Duo 10.

Even when I was leaning on my elbow, I could not feel the ground. I could feel the ground a little when sitting down, but it was still pretty comfortable because of all the foam inside.

If I make the Exped MegaMat really firm though, I can’t feel the ground in any position, even when sitting down.

This is a picture of me lying down on my Exped MegaMat Duo 10.
This is a picture of me lying down on my Exped MegaMat Duo 10.

But I like it a bit softer, because then the foam of the Exped MegaMat contours to the shape of my body, and gives my body plenty of support. But even when it was very firm, it never felt stiff and was also pretty comfortable.

Dimensions

The Exped MegaMat Duo 10 in a Medium Double size measures about 73.5 by 42.5 inches, which is slightly larger than the marketed dimensions. It’s much, much smaller than a Queen or even a Full size though, especially in width.

This is a picture of 2 sleeping bags on top of my Exped MegaMat Duo 10 in a Medium Double size.
This is a picture of 2 sleeping bags on top of my Exped MegaMat Duo 10 in a Medium Double size.

Basically, it’s just the size of 2 regular sleeping pads put together (~ 72 by 20 inches). Not the most spacious for sure, but I found the Exped MegaMat Duo 10 in a Medium Double size pretty comfortable for 2.

Side Walls

The side walls are vertical, which maximizes sleeping space.

Surface

The sleeping surface is flat, not baffled, the laminated polyester surface fabric is soft against the skin, and is not noisy when moving around in bed.

Bounciness

As for bouncing, it’s very minimal even when there’s another person sharing the mattress, which is one of the benefits of having a self-inflating mattress instead of an air mattress.

Ease of Use

Valves

The Exped MegaMat Duo 10 has 2 valves along the side wall of the foot of the mattress, which are low-profile and flushed with the surface.

Both valves are labeled, one says “Inflate”, and the other “Deflate”.

Inflation

To inflate the MegaMat Duo, pull off the flap to the Inflation valve.

This is a picture of the Inflation valve of the Exped MegaMat Duo 10, which comes with an attached toggle.

This is a 1-way valve, and comes with an attached toggle that you can push into the valve for a faster inflation.

This is a picture of me inserting the toggle into the Inflation valve of the Exped MegaMat Duo 10.

I usually leave the MegaMat for about 10 to 15 minutes, and it’ll inflate to about 85% of the maximum firmness.

If you like your mattress really soft, you might not need to add in any additional air. But if you like it firmer, to add in more air, take the toggle out, and attach this end of the mini-pump to the inflation valve, and it’ll pop into place.

This is a picture of me inserting the mini pump into the inflation valve of the Exped MegaMat Duo 10.
This is a picture of me inserting the mini pump into the inflation valve of the Exped MegaMat Duo 10.

You can use your hand for pumping if your tent is not tall enough, but I prefer using my foot in taller tents because it’s much easier. I usually add about 10 pumps or so, but if you like it super firm, you can add up to 30 pumps. Maybe even more.

This is a picture of me using my foot on the mini pump to inflate the Exped MegaMat Duo 10.
This is a picture of me using my foot on the mini pump to inflate the Exped MegaMat Duo 10.

At about 1 second per pump, it takes at most 30 seconds to 1 minute to do this. Then, I remove the pump, and put the flap back on to close the valve.

How Storage affects Inflation

How quickly the MegaMat self-inflates depends on how you store it at home.

If you store it like the instructions recommend, which is the MegaMat unrolled with the valves open, it could self-inflate in as quickly as 5 to 10 minutes.

If you keep it deflated and stored in the stuff sack like this for weeks at a time, like I do because I don’t have a lot of space, it could take anywhere between 15 to 30 minutes. Could be more if you store it for much longer.

This is how I store my Exped MegaMat Duo 10 at home - deflated and stored in the stuff sack.

First-Time Inflation

If you’re inflating the Exped MegaMat for the first time, self-inflation will take about an hour. After that, you’ll have to pump it a lot, maybe 3 to 5 minutes, because it doesn’t fully inflate.

Exped then recommends leaving the mat inflated for 24 hours, to allow the foam inside to recover. I personally did not do this, and my MegaMat’s fine.

Adjustments

If you find the Exped MegaMat too firm, just open the Inflation valve again, and press on it gently to release the built-in flap, which lets a little air out for more cushioning.

This is a picture of me pressing on the built-in flap of the inflation valve of the Exped MegaMat Duo 10.

Deflation

To deflate the Exped MegaMat Duo, pull off the flap to the Deflation valve, which is slightly larger in size.

This is a picture of the Deflation valve (opened) of the Exped MegaMat Duo 10.
This is a picture of the Deflation valve (opened) of the Exped MegaMat Duo 10.

Then, I fold the MegaMat Duo in thirds, put my entire body weight on it, and then half it to get as much air out as possible. This usually takes me about 1 minute.

This is a picture of me using my body weight to deflate the Exped MegaMat Duo 10.
This is a picture of me using my body weight to deflate the Exped MegaMat Duo 10.

Folding it up properly will take another 1 minute and 45 seconds. Basically, I can deflate, fold up and store the MegaMat Duo all on my own in 2 minutes and 45 seconds, and I’m ready to go.

But I’ve done this dozens of times over the past year of using this MegaMat, so if your mat is new and not broken in, then it might take a little longer at first.

Stuff Sack

The Exped MegaMat Duo comes with a super convenient Smart Pack Sack, that’s what they call it, or a sidewinder bag with a roll-top, so I could fit the mattress back in easily even if it isn’t fully deflated.

There’s a small inside pocket where I put my mini-pump and the repair kit.

The stuff sack also has a shoulder strap for easy carry.

Portability

Packed Size

After deflating, the smallest packed size I could get the Exped MegaMat Duo 10 Medium Double down to is about 23 x 11 x 10 inches. Definitely not as small as it was out of the box.

This is a picture of the Exped MegaMat Duo 10 Medium Double when it was first out of the box.

The packed size will change depending on how you fold it and how much air you push out of it.

How to Fold

For me personally, I like to fold it in half before rolling it up. When rolling it up, I use my hands to grip the sides of the MegaMat, while using my knees and body weight to push air out.

It takes me about 45 seconds to roll it up the first time.

This is a picture of me using my knees, hands and body weight to roll up the Exped MegaMat Duo 10.
This is a picture of me using my knees, hands and body weight to roll up the Exped MegaMat Duo 10.

Then, I usually unfold it, and roll it back up a second time to push a little bit more air out, which takes another 30 seconds.

Then, I close the valve, store it back into the stuff sack, place the mini-pump into the side pocket, roll down the top like a dry bag, and buckle the strap together, which takes another 30 seconds. So, altogether about 1 minute and 45 seconds (excluding deflation).

Weight

The Exped MegaMat Medium Double weighs 7.2 pounds for just the mattress alone. The mini-pump weighs 1.6 ounces, the carry bag weighs 5.3 ounces, and the repair kit weighs 0.6 ounces.

Versatility + Sizing

Insulation

The Exped MegaMat Duo 10 has an R-value of 8.1, so it’s very well-insulated, and can be used for all seasons, including winter.

The Exped MegaMat Duo 10 can be used down to temperatures of -40C and -40F.
The Exped MegaMat Duo 10 can be used down to temperatures of -40C and -40F.

I used the MegaMat in summer temperatures between 60 to 80, and never felt too hot even in higher temperatures. (Although I’m a cold sleeper, and I like it warm when I sleep.)

Usage

It’s too heavy and bulky for backpacking, so you’re limited to car camping.

2-Person Tent

It doesn’t fill up the entire tent, so there’s some space for gear at the sides.

It also doesn’t reduce livable space at all, and I have plenty of space to sit up and also to crouch.

When topping air off, there’s enough space for me to pop in the mini-pump to pump it up.

4-Person Tent

There’s definitely enough space to fit 2 of these Medium Doubles, with even a bit of space leftover for gear.

I also have lots of livable space, and I can almost stand up.

Quality

Material

The surface of the Exped MegaMat Duo 10 is made of 50D nylon with a polyester laminate, and feels very smooth and very soft. When I press down on it, it feels incredibly plush.

This is a picture of me touching the top surface of the Exped MegaMat Duo 10.

The bottom feels less smooth and more rugged, and is made of 75D polyester for added durability.

Foam Quality

The self-inflating foam is made of polyurethane, and recovers well despite being put in storage for a long time.

Seams Quality

The seams are welded and feel high quality.

Sometimes I would carelessly pick the MegaMat up like this without thinking, but the seams have never split on me.

This is a picture of me picking up the Exped MegaMat Duo 10 by its seams.

Valves Quality

These FlatValves are low profile, I really like that there are separate valves for inflation and deflation, and that the deflation valve is also slightly larger for a quicker deflation.

This is a picture of the inflation and deflation FlatValves on the Exped MegaMat Duo 10.
This is a picture of the inflation and deflation FlatValves on the Exped MegaMat Duo 10.

The valves are good quality, and I never had any issues with air leaking in the few weeks that I was using this MegaMat.

Air Retention

Speaking of which, air retention is very good. I slept on the MegaMat Duo with another person (about 300+ pounds together) 3 nights in a row without having to top off any air at all. I’ve also used this on my own for weeks at a time, without having to top off any air as well.

Pump Quality

The included mini-pump seems small at first, but it does the job very well. The correct way to use this is to use your hand or foot to seal the hole in the middle of the pump when pressing down.

This is a picture of me using my hand on the mini pump to inflate the Exped MegaMat Duo 10.
This is a picture of me using my hand on the mini pump to inflate the Exped MegaMat Duo 10.

When you lift your hand or foot, lift it off the hole completely, so that the pump can suck more air back in for pumping.

Even though I’ve stored this mini-pump deflated inside the stuff sack with the MegaMat for months at a time, the foam inside seems very resilient and never lost its shape or pumping abilities.

Stuff Sack Quality

The stuff sack has no loose threads or anything, and seems to be really strong.

This is a picture of the seams on the stuff sack or Smart Pack Sack of the Exped MegaMat Duo 10.
This is a picture of the seams on the stuff sack or Smart Pack Sack of the Exped MegaMat Duo 10.

The roll-top gives you versatility in packing the MegaMat away as tightly or as loosely as you want it to be.

Overall, the Exped MegaMat Duo 10 is extremely well-constructed and feels very durable.

Pros and Cons

Pros

For pros, the Exped MegaMat Duo 10 is super comfortable for so many reasons. It’s crazy plush, super soft, and the surface is flat so there’s no weird dips or contours that poke into your body. The fabric is quiet, bouncing is super minimal, and it’s also warm and well-insulated with an R-value of 8.1.

This is a picture of me using my hand to press down on the Exped MegaMat Duo 10.
This is a picture of me using my hand to press down on the Exped MegaMat Duo 10.

It’s also very easy to inflate, deflate and store. There are separate valves for inflation and deflation, the mini-pump is easy to use, letting air out if it’s too firm is a breeze, and the stuff sack is big enough to store the MegaMat even if it’s not fully deflated.

The Exped MegaMat Duo 10 is also versatile. It’s insulated enough to use in all seasons of camping, and can also be taken traveling. And the Medium Double is a very nice size. Since it’s just the size of 2 regular mats, it fits nicely into all 2-person tents. And you can fit 2 MegaMats in a 4-person tent, and so on.

This is a picture of the Exped MegaMat Duo 10 (placed horizontally) inside a Coleman 4-Person Dome Tent.
This is a picture of the Exped MegaMat Duo 10 (placed horizontally) inside a Coleman 4-Person Dome Tent.

It’s also incredibly high quality and well-constructed, from the sleeping pad, its seams and valves, to the pump and stuff sack.

Cons

As for cons, the biggest one has to be that it’s expensive. As with all other self-inflating mattresses, it’s also a little bulky, so it can’t be used for backpacking.

Recommendation

And here are 4 questions about the MegaMat that I’ll be answering.

First, who would I recommend the Exped MegaMat Duo 10 to? I’d recommend it to people who camp frequently and are tired of having their air mattresses fail on them, if you prioritize comfort and quality, if you need a 2-person mat to take winter camping, and of course, if you have enough spare cash in your budget.

This is a picture of the Exped MegaMat Duo 10 Medium Double out of the box.
This is a picture of the Exped MegaMat Duo 10 Medium Double out of the box.

Second, is the Exped MegaMat Duo worth the price? Well, I’ve had the MegaMat for more than a year now, and I’ve used it easily 3 months over the past year. It’s still going strong. I like that I can walk, stomp and bounce all over it, and it’s easily the most comfortable 2-person mattress that I have.

This is a picture of me stepping on my Exped MegaMat Duo 10.
This is a picture of me stepping on my Exped MegaMat Duo 10.

It’s my go-to mattress whenever I’m car camping or backyard camping, or for unexpected guests. Oh, and warranty’s also for 5 years. So, for the added durability and comfort, I say yes, it’s worth the price. It’s way better than buying a rubbish inflatable mattress every few months or so.

Third, is this Exped MegaMat Duo 10 as comfortable as my regular bed at home? Honestly, I think that depends on what kind of bed you use at home. For me, I just bought a new, really plush, hotel-like bed, so no, this MegaMat is not more comfortable than that. But there were a few people that I loaned this MegaMat to that said “whoah, this feels like a normal bed”.

This is a picture of me running my hand over the surface of the Exped MegaMat Duo 10.
This is a picture of me running my hand over the surface of the Exped MegaMat Duo 10.

So, yeah, it depends. But what I can tell you for sure is that this Exped MegaMat Duo 10 is definitely super comfortable, and more comfortable than most, if not all, other 2-person camping mattresses and sleeping pads. And I can speak from experience because I have like 10 of them.

Bonus: Must Read!

Fourth, how does the Exped MegaMat Duo 10 compare to other 2-person camping mattresses? Well, here’s a blog post where I bought, tested and compared 10 of the best camping mattresses for couples.
