very good info
Very good info collected here and I am glad I asked. Thank You. I think the bottom line is that I am on the upper end of that boat and it is going to be difficult to get my knees closer than what it is already. But I will try to reduce the amount of foam and that will give me a bit more room under the deck while hopefully still give me enough space to drive my legs in. I will cut the remaining pieces of plastic with the back band to widen the space around my hips as well as perhaps add thermarest to create back support and this will perhaps drive me forward an inch.
Actually
there’s quite a bit of contact, and you adjust the inflation until you’re comfy. The pad can be up to 4 inches thick.
I thought it was a gimmick until I tried it
