This is what I do. If I do need room in inventory I will break them down into wood it isn't a deal breaker because wood is easy to come by but as long as I have room in inventory I keep them.Yeah, wooden chairs have always bee the go-to wood burning source. You don't have to craft or shop anything. Just pick them up and stack 'em. Easy peasy!
Funny thing about coal, it burns a lot longer in West Virginia than in the game. Just sayin'...
