I'm so glad someone else has tried this with a chair kit. I was expecting much less specific advice.

I am a little worried about sliding off the chair overnight since there's no margin. I always bring a homemade rain kilt that I use as a mini ground sheet for my pack and shoes, but it may make sense to sneak a plastic sheet since I won't cry if it gets holes. I think I have some window film in the garage.

Out here, we have to cook and eat away from camp, but that'll be a bit nicer with a chair on the ground.

The mosquito solution may have to be a head-net, which I hope will make evenings more pleasant since I won't have to retreat to my shelter. Once it gets cold overnight, the bugs stop flying and I can take it off to sleep or keep it on to trap a little warmth.
