Ergonomic Balance Chair, Proportion Chair, with Auxiliary Cushion

Ergonomic adjustable height balance chair with a gray fabric finish.

This appears to be a used Miyata Seisakusho Proportion Chair.
It can be used by both children and adults, so I purchased it used several years ago for back pain relief and posture correction. However, I only used it a few times and it has been stored for a long time. It is a wooden product and can be used for a long time, but I am selling it due to decluttering and needing more space.

The cushion might be a bit saggy? There are no pets or smoking, so there is no odor, but there are signs of use. Please refrain from purchasing if you are concerned about used items.

For shipping, I will remove one of the center adjustment screws to make it smaller.
It is easy to reattach, so please understand.
The item will be wrapped in a plastic bag for shipping.
I believe it will be between 140-160 size.
