You missed the, 'it depends', option on the poll.
If I've to carry it any distance, forget it. I'll just sit on a bit of waterproof fabric......you can get yards of cheap stuff meant to cover garden furniture for £1.
If it's a settled weekender somewhere with loads of company and the blethering around the bushcraft tv, I'll take a chair.
Actually, for the Moot, I headed to Tesco and just bought one to use there. I did eye up Cobwebs sticks and hessian sack one with some envy though, but the woods wouldn't survive us all taking enough for them if we did it every time we were out. Cobweb takes hers from home and reuses

but that's just a different chair really I suppose. I can make the wee three legged stools, I can make the four logs hammered in and cross sparred, I can make the hammock chair, but it's the same necessity to cut down to make them.
So, it depends where and when and how long, tbh.
cheers,
Toddy
