Adjustable Steel Stool for Workstations

The National Public Seating stool uses 18-gauge steel construction and supports up to 300 pounds. A 14-inch diameter masonite seat is recessed into the pan and secured with eight rivets. Legs adjust from 25 to 33 inches high for a custom fit. A welded foot ring adds comfort during extended use.

Replacing Fixed-Height Seating

This stool replaces fixed-height chairs when multiple users share a work surface or when tasks require different working heights. The adjustment range covers 25 to 33 inches, so the jump is worth it when a single seat must serve sitting and perching positions. The 300-pound capacity handles heavier users that lighter stools cannot.

Build Integration and Space

The footprint spans 15.25 to 17.5 inches wide and deep, fitting tight corners and narrow aisles. No external power or tools beyond the included leg extension kit are needed for assembly. The compact base frees floor space for carts or storage underneath. Buyers needing a backrest, casters, or a larger seat diameter should look elsewhere.

Questions about this item

What floor space does the 18-gauge steel base occupy when the legs are fully extended?

The base measures 15.25 to 17.5 inches wide and deep depending on leg extension position.

How are the leg extensions secured during assembly, and which step is most often missed?

Extensions slide into the frame and lock with set screws; the step most often missed is tightening those screws before use.

What part of the 14-inch seat would need replacement first under heavy daily use?

The masonite board recessed into the pan and held by 8 rivets is the wear surface that may eventually require replacement.
