Here is the one year review of the MegaMat in the Winter 2014 issue of Overland journal.

The restorative properties of REM sleep are impossible to quantify. There is also no better way to spoil a good slumber than with a sharp stick in your back or a rock under your hip. As people who spend a great deal of time in the backcountry, our sleeping pad review was not just an editorial musing for the sake of filling space; we had a vested interest in discovering the most comfortable sleeping pad available. Winning the contest without threat of a close second was the Exped MegaMat 10 LXW. 

At 4 inches think, 77 inches long, and 30 inches wide, the MegaMat more than lives up to its name. The internal open-cell foam has lateral cored channels that give the pad a unique bed-like quality, while the vertical sidewalls maximize sleeping area. The included foot pump makes for easy inflation, and oversized purge valves expel air quickly. I have become such an ardent fan of the MegaMat that it trabels with me wherever I go; it has proven to be a better option than many proper beds. It isn't compact by any stretch, but the size is easily justified given the sublime sleep it affords. Our gear reviews often produce welcome discoveries, and this is certainly one of them.
