Exped MegaMat Duo Queen Self-Inflating Mattress Review

Our Verdict: Exped MegaMat Duo Queen Self-Inflating Mattress

A near-bed for two people with the warmest rating here, but it is heavy, slow to pack, and swallows most of your trunk.

A 4 inch self-inflating double with an 8.1 R-value and 52 inch width, it is the pick for couples who refuse to compromise on sleep.

What's the bottom line?

Four inches of foam gives a genuine bed feel that hides rocks and roots under both sleepers.

The 52 inch width and vertical side walls let two adults sleep without crowding each other.

My partner and I both slept through the night without touching, but it took the two of us grunting to get it back in the bag and it eats half the trunk.

Our Analysis, Comparisons, and Test Results

The Exped MegaMat Duo Queen Self-Inflating Mattress scored 90 out of 100 overall.

It is strongest on comfort and weakest on packed size.

Here is how it did on every metric we tested, with exactly how each score compares to the rest of the field.

Comfort

Four inches of foam gives a genuine bed feel that hides rocks and roots under both sleepers.

The 52 inch width and vertical side walls let two adults sleep without crowding each other.

Testers at Switchback Travel and OutdoorGearLab call it the top couples option they have slept on.

The updated version adds about 30 percent more foam coring for extra plushness.

Comfort	Rating
Best in test	10/10
Exped MegaMat Duo Queen Self-Inflating Mattress	10/10
Category average	7.9/10
Worst in test	6/10

Ease of use

Two deflation valves and a grab handle on each side speed up an otherwise slow pack-down.

A hand pump is included since the foam self-inflation alone does not reach full firmness.

But here is the catch:

Getting it deflated, folded, and back in the bag takes patience and a knee on the foam.

This is a two-person job to roll tight in the morning.

Warmth

An 8.1 R-value is at the top of the whole camping pad market, good for genuine winter car camping.

Thick continuous foam blocks cold from the ground far better than any air mattress here.

Owners report no cold spots even on frozen or cold-shoulder nights.

This is the warmest pad in this dossier by a clear margin.

Worst in test	4/10

Versatility

Ideal for car camping, van builds, and guest use, but far too big for carrying any distance.

The queen footprint needs a large tent floor, so check your tent before buying.

Strictly a drive-to, sleep-two mat.

Worst in test	6/10

Packed Size

Rolls to a massive 12 by 31.5 inch bundle, roughly double most other pads here.

Weighs nearly 12 pounds, so plan for a big trunk or roof box.

It is challenging to deflate and repack, the worst packed size in this group.

What Other Camping Mattresss Should You Consider?

Not sold on this one? A few others from our testing are worth a look.

The Therm-a-Rest MondoKing 3D Self-Inflating Mattress is our best foam-reinforced mattress. The most comfortable and warmest self-inflating pad here, but it is heavy and packs down to a fat roll you will only ever want near the car.

The Sea to Summit Comfort Deluxe Self-Inflating Mat is our best multi-purpose camping mattress. One of the most comfortable pads in the test and it comes in singles and doubles, but the foam is slow to compress and hard to cram back in the sack.

The OhGeni 20" Raised King Air Mattress with Built-in Pump is our best king size air mattress. A tall, easy-to-inflate raised airbed that sleeps three to four at real bed height, but like all airbeds it runs cold underneath and can develop leaks.
