I recently changed from a foam to inflatable sleeping mat.
I try to keep weight at minimum. I prefer a light hiking setup, so the inflatable mat weights 400 - 500 grams (1 lbs).
The problem is that I need to inflate it multiple times during the night. It leaks. The leaks are tiny so there is still air inside. I poured water into it and so I located the leaks (the area where water comes out). The method with air bubbles did not work. The problem is the design, even when using multiple patches, still leaks, and I need to inflate it again. Air always finds the way out in some new spot, even when patched. Sometimes I need to sit on the mattress so my weight is concentrated on one spot. Is that the issue that light mats can't take that?
There are a lot 1 kg or about 2 lbs mats. That seems too heavy for extensive hiking. So I ask you is it normal to expect, that 500 g (1 lbs) mat would last 15 usages or not? In some cases I sleep on good ground, forest soil. Sometimes there are rocks under tent floor (mountain areas) and I can't remove each one of them. I am careful.
I thank everyone for taking time and answering. I will buy new one from different brand and with different build structure.
