My kitchen island chairs were tatty, years old, surface rust and the upholstery had ripped. Briscoes had the same ones marked down to $60 so a no-brainer to replace them. Was resigned to throwing the old ones out, but realised the mechanism still worked sweet. Looked at various options to re-seat them, but couldn't really be arsed cutting and sanding timber, or spending money.
A bit of a polish with steel wool, some $9 bamboo cutting boards from Kmart and furniture insert nuts I had in my junk pile and done. Perfectly functional bar stools.
If something better turns up I'll just swap (old metal tractor seats would be cool)...
Now I need to build a bar I guess...
