Clinton Aluminum Base Pneumatic Stool with Backrest (2156-21)

The Clinton Industries 2156‑21 5‑Leg Pneumatic Stool with Backrest is engineered for superior stability, comfort, and long‑term durability in high‑volume clinical environments. Its 23″ cast aluminum base with satin top and black accents provides exceptional strength and balance, while the 5‑leg design enhances stability and reduces tipping risk during movement.

The large, easy‑to‑locate D‑shaped pneumatic height lever allows clinicians to quickly and smoothly adjust stool height, supporting efficient workflow. A 4″ thick firm polyfoam seat and ergonomic backrest provide long‑lasting comfort and lumbar support during extended procedures. The premium woven, knit‑backed vinyl upholstery is designed for daily cleaning and heavy use, while the chrome‑hooded dual‑wheel nylon casters ensure smooth, controlled mobility across exam room flooring.

The stool’s knock‑down design reduces shipping costs and allows for easy, no‑tools assembly. With a 250‑lb load capacity and optional caster upgrades, the Clinton 2156‑21 is a versatile seating solution for exam rooms, laboratories, imaging suites, and procedure areas. When ordered with the Extra‑Tall Cylinder, the stool can also accommodate an optional foot ring for enhanced ergonomic support.
