Now that you've selected a style have you determined if you need Desk, Counter or Bar height? Here's how to figure:
All furniture is measured in seat height. The height from the floor to the top of the seat.
A good rule of thumb is there should be between 9" and 13" between the seat height and the height of the counter or table where the chair or stool is going to be used. This will allow you adequet space to move about comfortably.
18" seat heights are designed to be used at 30" table, desk and sometimes at counter height.
24" and 26" stools are relatively new in the market place. They have been developed specifically for the kitchen counter in homes, where there is no longer a place or space for the conventional table and chairs. These stools are designed to be used at a counter height of 36" - 39".
30" stools are designed for bar counters that are 40" - 45" in height. This stool size is also suitable when being used in a family room around a pool table or shuffle board.
