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

If your mat seems to lose air overnight, the first step is to determine whether it's due to a leak or simply a natural drop in air pressure.

It's normal for a mat to feel softer in the morning if the temperature has dropped. For example, if you inflate your mat during the day when it's 30°C, and it cools down to 4°C overnight, the air inside will contract. This temperature change can make the mat feel underinflated, even if there is no actual leak.

If you still suspect a leak, here's how to check.

For Air Sprung Cell mats or lightweight Self-Inflating mats, you can fully submerge the mat in water and look for escaping bubbles. For larger or bulkier mats like the Comfort Plus Double SI or Comfort Deluxe SI, submerging the entire mat isn't practical. In that case, inflate it fully and use soapy water to wipe down the surface and check for bubbles.

Start by checking the valve area. Submerge just the valve section or apply soapy water to it. If bubbles appear, the valve insert may be faulty. This is often an easy fix with a replacement valve insert. Contact us if you need help with this.

If the leak is coming from the body of the mat, mark the spot with a ballpoint pen. Dry and clean the area with isopropyl alcohol, then use the repair kit supplied with your mat to patch it.

If you're unable to find the source of the air loss, or if the air seems to be leaking from multiple areas, please contact us through the warranty form so we can assist further.
