Thermarest TrailSeat

Thermarest is the BEST
This is one more thermarest cushion to add to my collection. I have a number of lumbar cushions that I use for multiple pain prevention purposes (to sit on, to lay on between the middle of my back at a low inflation, to brace my back in the car, to use in public seats (restaurants, movies, lectures, church). I almost never find a ergonomically correct seat and thermarest is light to carry, it folds up and can be used anywhere. I purchased this trailseat to give a wider cushion for sitting on top (e.g. in an airplane flight where the seat cushions are typically weak in the center and throw off the spine by not supporting the sacrum properly. Thermarest solves the problem.

Therma-rest Camp Seat
I use this in the car to cushion and support my back during long drives. It allows me to sit for extended periods by adding or letting out air as needed. An excellent piece of equipment!

Cool
I actually bought this to use on the floor of my tent. I don't have 20 year old knees any more, and I prefer to use them up on climbs not monkeying around for gear on hard tent grounds. Works great. Middle of the night scrounging much easier on the knees with the trail seat at hand.

Good product
I use it on my office chair, which does not have enough padding. It can be adjusted to provide just the right amount of support for hours of sitting.
