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.

Low $$, lightweight, complements inflatable pads.
I have used the TaR Z-Shield for several months now in the panhandle of Florida. In the backcountry, getting a good night's sleep is my top priority and I typically stick with inflatable pads. I used closed cell foam mats during college and the Z-Shield gave me the opportunity to try it again. It hit the marks with being lightweight and multi-function. I have used it to sit on sandy campsites, laid out my gear instead of on damp or muddy surfaces, and also used it to complement my inflatable and add some R-Value to my sleep system. It's been through the wringer while out on the trail and used personally at home. I have used the Z-Shield for my dog when we head out and don't have to worry about him puncturing my inflatable pad. Other TaR mats like the Ridgerest may be more durable, but I think the Z-Shield strikes a good balance with its weight, R-Value, and functionality of its accordion-style design. It may not be for those who need plush comfort to sleep, but for me it's about the balance between price, features, and longevity.

Good supplemental pad
I use this in colder weather when my Neoair Trekker is not warm enough when used alone. It also serves as a yoga mat.
