The Numbers™ Adjustable Height Chair & Stool by Smith System provides pneumatic height adjustment for classrooms and learning spaces that need flexible seating. Choose the chair or higher stool, then select its caster or glide model so the stated seat-height range matches the actual base.

The flexible Numbers shell supports different seated postures around the work surface. A Black five-star base supports both styles, and the stool adds a chrome footrest. Keeping the styles together makes it easier to compare height and mobility without confusing a chair-height model with a stool-height model.
