About this product

The Uncaged Ergonomics Wobble Stool Air is a rolling balance stool designed for active task seating in offices, home workspaces, educational environments, and shared work areas. Its fabric-covered air-filled wobble cushion gives users the option to sit still or add gentle movement and light core engagement during desk-based tasks. Unlike a bulky yoga ball chair, Wobble Stool Air uses a compact chrome-finish metal 5-star base that fits more naturally into professional spaces. Standard non-locking casters roll on hard floors and carpet, the seat swivels 360 degrees, and a gas-lift lever adjusts the height from approximately 19 to 25.5 inches. The stool is suitable for desk work, classroom and homeschool study, creative tasks, organized hobby areas, coworking, and flexible seating applications. Assembly is tool-free and estimated at under 10 minutes. Wobble Stool Air supports up to 250 pounds and includes a 1-year warranty. Pump not included. It is intended for desk-height task seating and intermittent active sitting rather than standing-height use.
