What is the difference between a stack chair and a nestable chair?

Stack chairs have a frame that stacks vertically, with one chair seat sitting inside the legs of the chair above — typically 4–8 chairs per stack. Nestable chairs roll together horizontally on a dolly, connecting seat-to-seat via metal hooks on the back legs, allowing 15–30 chairs to nest in a compact row. Nestable chairs require less vertical clearance for storage than stacked chairs. OfficeFurniture2go.com carries both stack and nestable conference chairs — call 1-800-460-0858.
