I wanted to say thank you to everyone who has made wonderful suggestions for seating. I have had a handful of responses here, a handful on facebook, and a handful via the Small House Society.
Out of the responses I've gotten, most have still seemed too big to apply now, in the limited space we have due to our lack of furniture otherwise... but I think the best suggestion I've heard has been Grant's idea of using office chairs. Originally I shied away from this idea because I was picturing office chairs without head support... but upon further consideration, there are some decent "executive" style chairs that have head support, though they are a bit more expensive. I suppose this might be the best solution though.
This just in...
Ho ho, every time you think things can't get worse, the cold water flow to the kitchen sink cuts out for no apparent reason... ;)
