My sleeping mat seems to lose air overnight, what's happening and what can be done?

The first step is to determine the source of the air loss. With an Air Sprung Cell mat or a lighter-weight Self Inflating mat, it is relatively easy to submerge the mat to check for bubbles. With a Comfort Plus Double SI or a Comfort Deluxe SI Mat, this is impractical, and wiping the inflated mat with soapy water is the best option.

Start by checking the valve – submerge just the part of the mat where the valve(s) are located. If bubbles come from the valve, replacing the valve insert may resolve the issue (contact us through our warranty form if you would like more details).

If the air loss comes from the body of the mat: Mark the point where the air is exiting with a ball-point pen, dry the mat, and clean the area to be repaired using isopropyl alcohol. Then use the repair kit supplied. You can find details HERE

If you are unable to find the source of the air loss, or the air appears to exit through a number of separate points, contact us via the warranty form We will need the following:

- Where and when the mat was purchased

- The production batch number (On an Air Sprung Cell mat this comprises of one letter and four digits and is embossed into the laminate on the inside of the mat. You can find it by opening the deflate valve. On a Self Inflating mat, this comprises of two letters and four digits, and is embossed into the seam at the foot end of the mat)

- Detailed images from the submersion test / soapy water test.
