Exped SIM Comfort 10 LW -

With a lofty design this self-inflating Exped SIM Comfort 10 LW sleeping pad is one of the thickest pads out there with about 4 in. of padding for dreamy refuge from the cold, hard ground.



  • High frequency welded seams and strong lamination of foam and fabric for durability. Delamination is generally the most common defect in self inflating mats and the reason why the lamination process gets special attention.
  • High-frequency welded seams create airtight construction
  • The Exped SIM Comfort 10 LW sleeping pad includes repair kit with adhesive and fabric patches
  • Laminated polyester fabric is both durable, airtight and humidity resistant. The shell‘s top surface is of brushed polyester fabric that provides excellent slip resistance and comfort next to the skin.


  • Features 2 wide, low-profile, FlatValves for inflation and deflation; pad self-inflates, but to top off, inflate easily with a few hearty breaths


  • Generously sized stuff sacks for easy packing.


  • Intake valve features a built-in flap to prevent air escaping when inflating; flap can be released to let a little air out when finding that ideal comfort zone
  • Exped SIM Comfort mats inflate quickly through Exped's exclusive FlatValves, one each for inflation and for deflation.


  • Includes stuff sack for protection during transportation
  • SIM = Self Inflating Mat; LW = Long Wide
  • Both edges of mat feature rip-and-stick strips so can you attach another mat or 2
  • Only CFK-free, high grade open cell polyurethane foam is used of 16 kg/m³ density.
Ramsey Outdoor
The “Fat“ mat for an expedition base camp, RV, or portable guest bed. A truly luxurious mat with velcro strips that enable joining of 2+ mats. Horizontal cores reduce weight and bulk. 2 valves for quick inflation and easy deflation.

Sooooo Comfy!

So like any exped product, this one is a winner too. I also own their synmat7. I got this pad beacuse I started car camping more than backpacking and wanted something nice and fluffy unlike a cheapo air matress. Inflation took 24hrs this first time around, but since then no problems inflation takes 20-30mins. Easy to deflate and pack. Nice materials, rugged and held my big self in place no issue.

Call me crazy, but this thing did not feel like it weighed the 64oz it was advertised at, so to the scale it went. An even 3lbs. Now at 3lbs, call me crazy but I might take it backpacking cause it is that comfy and I would carry the extra pound for a better nights sleep. It would be bulky, but if you sleep better the next day will be better.

There is only 1 thing I didn't like at first. The edges, they curve down a little bit. This could make it easy for someone to slip off IF they sleep with a very firm mat, I don't so no issue here. I've spent 3 nights on it so far. I should add I am a side sleeper and this is the most comfortable mat I have ever used. Well worth the money!

Awesome sleeping pad for car camping

Excellent sleeping pad for car camping-type uses. Super warm and comfortable. After the first full inflation, it self-inflates almost all the way by itself and holds air really well. The velcro feature is really nice too since my wife and I both have one. That way the pads can form 1 large mattress essentially, if needed. The pad is light for its size, but is still quite large even when rolled up into the stuff sack. I wouldn't ever take it backpacking, but for comfort, car camping, this pad is the best.

Good, but there are better choices

These days there are so many luxurious camping mattresses, it can be hard to choose the best one. I would rate the EXPED SIM Comfort 10 as quite comfortable, but I returned it in favor of the Exped Mega Mat and the REI Campbed 3.5 (I use both for different uses) for these reasons:

1) There is a distinct tendency to roll off the sides of the SIM. By comparison, the REI Campbed 3.5 and the Mega Mat provide a stable sleep surface.

2) The SIM is only slightly more comfortable than the REI Campbed 3.5 and not worth the extra money. The Campbed has a softer top surfance that feels better on bare skin.

3) The Exped Mega Mat is much more comfortable than the SIM. If you're going to pay this much money, you might as well go all the way and get the Mega Mat.

For sleeping on the ground the Mega Mat is definitely more comfortable than the SIM by a large factor. For sleeping on a cot the REI Campbed 3.5 is better (excellent, in fact) and cheaper.

I am not recommending the SIM not because it's not a good mattress---it is---but because there are better choices in this age of amazing mattresses.
