This is the design for the back of a dining chair Called the “Lumbar Cradle”
An orthopedist and me came up with the design. Where the chair back would contact the fewest pressure points when sitting and engaging the back at the optimal angle on the scalene muscles of the back.
So at the 5-7degree angle of the chair limited pressure would be placed on the thorax- cervical vertebrae.

Interesting idea and design detail. Are you going to band saw and sand it or do you have another idea for production?

We have some rocking chairs that are unusable to me. How they ever sold any was a miracle. They are flat across the back and bottom and hard as a rock. I would love to build something like this.

The bach is already ban sawed. I use my new craftsman “Roll sander to get the final contours. Here is a picture dry fit before band sawing.
