I have a Skyshed Pod observatory. It is a 7' diameter structure with a hard floor. I am currently using a secretary's chair on wheels, which is great. The obvious problem is that it only has about 6" of height adjustment. It doesn't go low enough, and it doesn't go high enough. I am looking for a chair or stool on wheels, that will go down to about 12" and up to about 30". Has anyone ever seen such a thing? I have a standard "astronomy chair" that is built like a step ladder that the seat slides up and down the rails, but it takes up way too much space, is very hard to move and the seat has a tendency to go to the bottom every time you move it. Any help or ideas would be greatly appreciated.
