Whenever I teach a chair class, I build a chair along with the students. I don’t always sell my classroom-built chairs because I always push myself to try something different on the chair – something I’d be afraid to do to a chair that I am counting on to put food on the table.
During last week’s chair class I crossed over a threshold I have been approaching for a few years: changing the geometry of the comb of a comb-back to the point where it sits more like a Gibson chair.
This is the most comfortable comb-back I’ve made to date. I don’t like to name my furniture, but for now I’m calling this a “short-back chair.”
What’s different about this chair compared to my previous designs in “The Stick Chair Book” (free for download forever)? Quite a lot.
I don’t have “plans” for this chair. That’s not how I design chairs. It would take me longer to draw plans for this chair than to build another chair. But I am happy to share the essential geometry so you can graft it onto one of your designs. (This is my Southern way of saying all gentle-like: No, I’m not going to create plans. All you need is in the free book and the information below.)
Seat Height
I have been gradually lowering the seat height of my chairs, as measured from the pommel to the floor. This chair is 15-1/2”. You might think that’s low. I don’t. I think tables are too high. When one of the students this week asked how low chair seats could go, I replied: “Many Morris chair seats are 12” off the floor.”
Back & Seat Lean
The back of this chair leans back 16.2° from the seat. The seat tilts 4.15° back. That’s a total lean of 20.25°. No, it doesn’t feel like a dentist’s chair. If you are using the chair plans in “The Stick Chair Book,” you achieve this 16.2° angle by positioning the front edge of the arm 1-1/4” behind the back edge of the seat. The seat is tilted back “two fingers.”
The Comb
My big comb-back chairs have the comb about 15” above the arm. That makes for a big and impressive chair, but you have to arrange the sticks so the sitter’s shoulders don’t feel like they are being poked by a bunch of sticks.
In this chair, the bottom of the comb is 8-3/4” above the arm’s shoe. This means the comb supports the shoulders – the sticks are taken out of the comfort equation, which means the comb must be a comfortable curve. This one is 18” long and has a 20” internal radius. The top edge of the comb tilts back to add a little comfort.
What’s Next?
I’m going to move the comb down 3/4” next time. I have a hunch that will help even more. (I could be full of crap.)
This chair is currently in paint (“Twilight” in General Finishes acrylic). Megan is patching a bit of blow-out on the arm (the bit of white in the photo). This chair, while experimental, is good enough to sell. I’ll post it for sale on the blog in the next week or so. It is made of elm with ash sticks. The chair will be $1,500 (which will include shipping). We’ll sell it via a random drawing.
