Query: Not Very Adjustable

The stool is not bulky and looks nice in my home. However, I'd prefer a more adjustable chair. For instance, the seat back does not adjust front and back, and the seat bottom does not tilt forward. The lumbar support feels good against my spine, but it deflates every day. The foot support ring diameter is too small that it might as well not exist; it's not a comfortable foot position. The seat bottom is very comfortable, so I'm interested in testing other Tiffany Office Furniture products.
