I was wondering if any of you have ever cut your therm-a-rest self-inflating pad down to fit your height and then re-seal it some how? I have a base camp and wish I could cut the length down to save weight. No sense carrying extra length pad around that I will never use. I know there are other pads that are lighter, but I don't have the money right now to spend on another one. I figure I would cut off about 10 inches, any ideas?

If you have a way to heat seal it, then you should be able to. I have never done it.

I have modified a therm a rest with no problem. I left the mat out one time and when I returned something had decided to have it for lunch. The critter chewed on the sides right in the middle of each side areas. Both sides! I trimmed the areas picked off as much foam as I could to leave a 3/4" margin for gluing. Before gluing I used a scotch brite pad to clean any remining residue off. Next I took Seam Grip and applied to both sides and clamped the area with 2 wood strips. I also put wax paper on the nylon before clamping with the wood strips. Let dry for 48 hours, did a pressure test by over inflating and then layed on it for a length of time. Also checked in the tub filled with water. Worked like champ ever since. You could apply the same principle to modify your mattress. I have often though about tapering the sides in where you don't really need the support to save weight.

Thanks for the information! I may try that, I'm just a little scared to try it on a good pad. I will try to put my hands on a used one and see if it works for me. BTW, I called Therm-a-rest and they won't cut it and re-seal it for me. I figured I would call just to see what they would say. I am 5'8" and don't want to carry that extra length for nothing!

just checking , have you attempted to cut your base camp yet? If so what kind of results did you have?

Not sure if the Base Camp material bonding is vastly different than the Neoair, but here is a video on how to reseal the latter. Several have done it with success but it does take the proper temp and practice wouldn't hurt. wink
