Therm-a-Rest® Introduces the World’s Fastest Self-Inflating Mattress

Therm-a-Rest® has been perfecting the camping mattress for 45 years, and the latest pad is the culmination of that quest. For 2017, the Irish-based business is introducing the Trail King™ SV—the fastest self-inflating mattress yet. By fusing AirFrame™ Construction, which alternates channels of foam and air, with the SpeedValve™, Therm-a-Rest has created a mattress that inflates in seconds, and deflates in a flash, giving you more time to have fun outside.

Weighing just 1 lb 13 oz, the Trail King enters the 2017 market as a mattress light enough for backcountry travel, but its 2.5 inches of loft provides a level of comfort car campers expect. At £110.00 and €134.95, this makes the Trail King a value for campers who desire versatility in their gear.

The true magic of the Trail King, however, is how easy and fast it is to use. Just open the proprietary SpeedValve—which uses physics to draw in surrounding air—and watch as the mattress’ alternating foam and air channels expand before your eyes in a flash. Top it off with a few breaths by blowing into the SpeedValve and you’re all set. And when it’s time to get back on the trail, the proprietary, auto-reversing SpeedValve will allow you to deflate the mattress in mere seconds.

The Trail King™ SV is available now in selected retailers. For more information on Thermarest SpeedValve™ technology visit
