Product Description
FIRM ⢠SOFT ⢠LUXURY
MegaMat Auto is the ultimate vehicle sleeping mat fitting many mid-size trucks, compact SUVs & wagons, and Tesla models.
Like other sleeping mats in the MegaMat line, the MegaMat Auto features 4 inches of open-cell polyurethane foam for soft support and warmth. The brushed stretch tricot polyester face fabric creates a luxurious cradling effect.
MegaMat Auto is self-inflating. Open the inflate valve to allow the foam to expand and draw air into the mat. Use the included Top-Up Pump to dial in your preferred firmness.Â
What does a "soft" comfort experience mean?
MegaMat provides soft, pressure-relieving support that cradles the body.
It is the âGoldilocksâ comfort experience of the camping mat line and is an ideal choice for both back and side sleepers.
Features
-
Wheel well cutouts
Asymmetrical mat shape fits between the wheel wells of many vehicles. Turn your vehicle into a trailhead hotel.
-
Welded grab handles
3 practical welded side handles make for easier handling and carrying ability; no more awkward mat grappling.
-
2 inflate & 2 deflate valves
2 sets of one-way inflate & deflate FlatValves, one at the head end and one at the foot end, allow for easy inflation & deflation no matter the mat's orientation in your vehicle.
-
Soft, recycled material
The soft & stretchy 100% recycled tricot polyester face fabric ensures maximum next-to-skin comfort & enhances the cradling effect for a truly luxurious night's sleep.
-
3D construction
Vertical sidewall construction maximizes available sleep area & reduces tapering at the edges â just like your bed at home!
-
Self-inflating mat
Open the one-way inflate valve & insert the valve pin to speed up inflation. Top-Up Pump included to add air to your desired firmness.
MegaMat Technology
Foam & air work together to form the base of your camping mat.
Horizontal air channels in the foam take in air during self-inflation and purge air again for easier packing & storage (not to mention saving you a little extra weight).
The cast-away foam pieces removed during the coring process are repurposed and used in other pieces of gear, such as our foam chip-insulated camping pillows.

FAQs
What is R-value?
R-value is a measure of thermal resistance. It indicates the efficiency of insulation by measuring its resistance to heat transfer. The higher the number, the slower the rate of heat transfer through an insulation.
In EXPED sleeping mats, higher R-values help sleepers retain the heat their bodies generate and the result is the pleasant and sometimes elusive condition called warmth!
Can I use an electric pump to inflate my mat or pillow?
You can use the EXPED Widget electric pump to inflate your mat. The Widget is relatively low power and can be used for all EXPED mats and pillows. We do not recommend the use of any electric pumps other than the Widget because overinflating your mat or pillow can cause irreparable damage.
What do I do if my MegaMat isn't inflating on its own?
When our mats are stored in a compressed state for prolonged periods, the interior foam gets used to its compressed (rolled-up) shape and can cause sluggish self-inflation of the mat.
We also like to point out (since many overlook it) that the mats come with an âinflation wedgeâ (looks like a zipper pull) piece next to the inflate valve. This is designed to be inserted between the plastic valve wall and the green silicone âflapperâ seal to create an adequate gap for air to enter the mat. If your matâs foam seems compressed, filling the pad to full inflation (until the mat is firm) and leaving it inflated for a few hours should be enough to de-compress the memory foam and restore the mat's self-inflating ability for subsequent uses.
How do I clean my mat?
The first step is to make sure all valves are fully closed. We recommend cleaning your mat with warm water and a mild soap. Do not use bleach to clean your mat. If needed, you can use a rag or soft sponge to carefully scrub the mat.
After using soap, rinse it well. The mat should air dry after cleaning. Do not put your mat in a washing machine or dryer.
How should I store my mat?
Store your mat in a cool, dry place, unrolled with the valves open and out of reach of pets with claws.
Rooftop Tents:
Itâs fine to use and store the mat in a rooftop tent while on
a trip, but in warmer climates, we recommend leaving the valve caps open during
the daytime as a precaution so that the mat cannot overinflate from the heat of
sun exposure.
In general, it's good to keep the mat somewhere cool and dark to
minimize damage from excessive heat or UV radiation. Itâs also best not to keep
your mat in a rooftop tent year round for long-term storage.Â
