TRADITIONAL ROUND ASSISTANT STOOL • VALUE-FOCUSED DESIGN
Reliable assistant seating without complexity—comfort and functionality at exceptional value

Straightforward Excellence: Deep Comfort Without Complexity
Traditional Round Seat • Single-Lever Simplicity • Ratcheting Arm

The Keystone C40AR delivers traditional round-seat comfort at exceptional value without sacrificing the functionality assistants need. The deep, contoured seat with high-resilience molded foam provides superior cushioning perfectly sized for medium to tall users above 5'4"—creating unparalleled comfort during extended chairside sessions. This straightforward design eliminates unnecessary complexity, focusing on what matters most: reliable support and practical functionality for daily clinical work.

Engineered for assistant efficiency, the single-lever adjustment system provides easy, intuitive control—no complicated multi-lever mechanisms to adjust between patients. The ratcheting arm positions precisely for instrument transfers during four-handed dentistry, while the adjustable foot ring with tall cylinder (23"–30") enables optimal elevated positioning for visibility. Full tilt adjustment allows comfortable positioning throughout procedures, and the five-leg powder-coated aluminum base ensures rock-solid stability during dynamic assisting movements.
