Hi Neal,
Thank you for your response. Sorry I did not respond sooner. I lost the bookmark to the site, but then remembered I could find it in my Internet history (yay).
The kitchen is small. The distance between cupboards varies because of a kitchen island. In some places it is just 3 feet, but the main area is about 5 feet.
There is only one place where he has to fit through the 3' space, which is like an entry from where the island divides the kitchen/cooking area from the kitchen/eating area. The kitchen/cooking area is like a square, around 5' across.
The chair has a 28" wide seat, plus the chair arms. Turning radius of the chair is 26.75. Overall length and width of the chair is 45.25" Long by 30" Wide.

The kick-plate is around 3" off the floor. It goes under the cabinets which is also a problem because it hits right at his toes. He has demolished his toenails by running them up under the cabinet three times so far.
I like the bumper idea and actually looked into adding some like those you see in hospitals. This could help save other areas of the house that are getting torn up, such as door frames and the walls.
Much of the damage to the kitchen cabinets happens when he turns too closely or backs into them. The backside of the arms rams them and the damage is towards the top of the cabinet doors. He really tries to be careful, but our cabinets are not very durable.
Thanks again,
Leeann
