Documents and Instructions

Click here to download the Universal Therm-a-Rest Mattress Repair Instructions, including how to locate leaks and make repairs in the field or at home on any mattress model.

If you have further questions about repair or warranty, or would like to send your mattress to us for repair. In the U.S., please contact our Customer Service department at 1-800-531-9531. For worldwide service and repair contact information, please click here.

Should you find yourself without access to Therm-a-Rest Repair Kits, repairs can also be made using items commonly found at most outdoor gear shops. (Remember that for maximum effectiveness, ALL of the below repairs should begin with a clean and dry mattress. An alcohol swab is an ideal cleaner that dries fast.)

  • Small leaks not requiring a patch: A urethane-based glue should be used. Some popular brands are SeamGrip® and AquaSeal. Apply a small dab, large enough to completely seal the hole, and allow 24 hours for drying. If your mattress fabric is relatively smooth like the NeoAir or Trail mattresses, peel-and-stick bicycle tube patch kits are an option offering instant repair.
  • Larger holes and tears: All mattresses can be repaired with a self-adhesive fabric patch—like those used to repair jackets and tents. These are commonly found in outdoor gear shops. Cut the patch in a circle to generously cover the hole. Apply a small amount of urethane-based glue to the back of the patch and the area to be covered on the mattress. Apply patch and press firmly. Wipe away excess glue from edges and allow 24 hours to dry.

If you’re not comfortable making the repair yourself and have some time before your next trip, call our service department at 1-800-531-9531 for instructions on sending your mattress back for repair.

Yes. A Therm-a-Rest Valve Replacement Kit will replace all metal and plastic mattress valves. Instructions for the kit can be found here.

Roll the mattress up to force the water out of the open valve. If there is a lot of water, you may have to do this several times. Hang the mattress upside down with the valve open in a warm, dry place. It will take about three days for the mattress to dry out.

Regular cleaning will extend the life of your mattress, especially if you sleep in direct contact with its surface.

Do not put your mattress in the washing machine. Cleaning with a hose or in a bathtub is best. Do not forget to close the valve while washing. For general cleaning, a quick scrubbing with Formula 409®, BioClean All-Purpose Cleaner, or other general household cleaner is best.

For tree sap, spot clean with a cotton rag soaked in rubbing alcohol. This will take some work and sap will likely leave a stain. However, a dusting with talc or baby powder when you are done should eliminate any residual stickiness.

Perfect for music festivals
I've bought my Thermarest Trail Lit half a year ago and I'm still as excited about it as the day I bought it. I've used the matress on many music festivals. After strolling around the festival all day I'm glad that I can go to sleep on a high quality, durable and warm matress. I used to bring a bulky 2 person air matress for me and my boyfriend. But now we both have a thermarest. It packs down easy and is very light. Just put it in your bag and you're good to go. I recommend this product to everyone!

Long live the king!
I have put many nights on this pad. Its been on multi-day canoe trips in Tennessee, on a week long whitewater rafting trip through the wilderness of southeastern Oregon, on many backpacking trips on the coast, in the mountains, the desert and all around the Columbia River Gorge! Lately its been exploring the southern Rockies. I have never had a single issue with it losing air or for not self inflating. In fact the only issue I have had was when I laid it too close to the campfire this past winter and burned several holes in it. 2 of them clear through both sides of the pad. I thought it was done but still had another night to sleep on a flat pad before hiking out. I gobbed some aqua seal over ther holes and allowed it to set up. It worked! Holds air just as good as it always did. Now I have 3 or 4 trips on the patched pad and its as good as new! Hopefully I won't be buying a new sleeping pad any time soon but if I do you can bet it'll be a Thermarest!
