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.

Never used another brand!
I've always had Therm-a-Rest mattresses. Norway, France, Scotland... We bought this for use at BaseCamp. After one of our old Therm-a-Rest was destroyed by a sharp point on the attic. We use different mattresses when backpakking.

Super comfortable
I gave my old (well used and fantastic) thermarest mattress to a friend in need (his budget mattress had collapsed!) and decided to treat myself to a Basecamp mattress as I mostly take my car when I go camping these days. So glad I did because this mattress is super comfortable (like my old thermarest was) but has just that bit of extra thickness that means that it helps keep me nice and warm from the cold ground when I'm winter camping. It's perfect cosy comfort means I get a great nights sleep whatever the ground conditions or weather conditions. Would 100% recommend this mattress as long as weight isn't an issue for you.

Oldie, but a goodie
Over the years I've acquired a number of different Therm-a-Rest mattresses, but I still own and still use my original Therm-a-Rest from the mid- 70's. One of the rust color ones with a brass bicycle style air valve, what became today's Basecamp. Still going strong, never had a leak, and not so bad for 40 some years of use. It's probably going to outlast me and will become part of my estate.
