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.

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.

No, I would not recommend this to a friend
do not buy - terrible
I purchased 2 of these mats. One for me and one for my friend as we are walking the bibbulmun track 1000km in Western Australia. Her mat went down on the very first night. It had come straight out of the packet into her bag, we had looked and looked for a leak. Nothing. As we were on the track, with no way out there was not a solution. we figured that it was probably just faulty. On the 4th evening my mat suddenly decided it would also join the deflation party. What!!! Now both mats are faulty!!! Very very odd. We have an amazing tent which does not have any punctures, both mats have never been anywhere but in our tent. When we arrive home I will be returning both mats!!!!!!

Disappointed
I reviewed this mat before i purchased and I must say I am extremely disappointed. I am on a 1000km hike on the Bibbulmun track WA, and my mat keeps deflating within an hour of lying on it. I have watched the video and have had numerous people look at it with no avail. I have spent the pass week sleeping on the ground as there is no way of the track or place to purchase a new mat. Very unhappy with the product.

Neo AIr XLite Max SV
I have owned a regular Neo Air for several years but wanted something easier to inflate. The new speed valve is amazing. It works as advertised. I no longer have to carry an additional pump .
