Stop in for a cup of coffee

That's what I figured on doing but as you can see in the picture I would have to extend the bottom out about a foot so the chair could swivel all 180* and not hit your knees on the support. I don't think the steak pockets can hold up to much weight. I weigh 140 and it's fine but put a 200 plus guy on it and I don't think it would hold up for long.
I would mount them from the frame. How many seats are you planning?
