The updated Megamat LXW remains one of the most comfortable sleeping mats available for basecamp use
Exped says:
Mega in size, comfort and warmth – the MegaMat is the ultimate mat for basecamp, a camper bus, or a guest bed.
The unique 3D construction offers the largest possible sleeping area. The core of the MegaMat features just the right density, 10 cm thick foam that provides exceptional support and insulation. Horizontal air channels within the foam help reduce weight and packing size without compromising comfort.
The MegaMat is self-inflating. The desired firmness can be easily achieved with the new top-up pump supplied. The two flat valves allow the air to be inflated and deflated quickly and easily. Also included is our practical Sidewinder Bag for quick and easy packing. The surface is crafted from soft recycled stretch tricot polyester, ensuring a delightful feel against the skin.
Our Verdict
The 10 cm foam provides a flat, stable surface that remains supportive without bottoming out. At 2532g, it’s not designed for portability, but the comfort and insulation (R-value 8.1) are excellent for vehicle-based trips or cold-weather camping. The new dual-valve layout accelerates both inflation and deflation, while the updated foam coring enhances pack size without compromising firmness.
The new welded side handles are genuinely useful for setup and repositioning. The surface fabric feels soft against the skin, and the use of fully recycled materials across top and base is a welcome upgrade. The packed size is still bulky, but for situations where weight isn’t a concern, it’s hard to beat. A well-refined and durable mat that continues to prioritise comfort above all else.

ASTM R-Value:
From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.
You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.
In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.
