TopJob BOBA Armless Fabric Active Sitting Stool, Mocha (311015619)

• Backless, armless active sitting stool built for focused work at a desk or standing desk, and for any spot where a full task chair would be too much furniture.
• Upholstered in a water- and stain-resistant eco-friendly fabric over high-density foam in Mocha, so everyday spills wipe away instead of setting in.
• Ergonomic through movement rather than padding: the tilting base keeps your hips making micro-adjustments, which holds your pelvis upright and your core engaged.
• Overall dimensions: 20" to 25"H x 15"W x 15"D, with overall height set by the seat adjustment.
• Seat dimensions: 20" to 25"H x 15"W x 15"D - a 15-inch round cushion adjustable across a 5-inch height range on a pneumatic gas lift.
• The BOBA is backless by design, which is exactly what keeps you sitting actively instead of reclining.
• Arm style: armless. With nothing at the sides, you can pull straight up to a desk, mount from any direction and turn freely.
• Tilt mechanism: an omnidirectional tilting base that leans up to 50 degrees in any direction, plus a full 360-degree swivel.
• Capacity: supports up to 330 lbs.
• Assembly required and quick - the seat, Class 3 pneumatic gas lift and base go together with the included hardware.
• Certifications and standards: BIFMA certified, built on a commercial-grade Class 3 pneumatic gas lift, and tested PFAS-free.
• Warranty: 7-year limited warranty.
• Weighs 18 lbs on its own and 23 lbs boxed, so it moves between rooms easily. Designed in Boston and assembled in China.

Your body was never built to hold one position for eight hours, and the BOBA is the piece of furniture that takes that seriously. Where a task chair invites you to settle, the polyamide base tilts up to 50 degrees in every direction, turning sitting into a quiet, continuous negotiation between you and gravity. The result is an upright spine and an engaged core without a single conscious reminder.

Materials and durability. The 15-inch round seat is high-density foam under an eco-friendly, swimwear-grade fabric that resists water and stains, over a polyamide base and a commercial-grade Class 3 pneumatic gas lift. It is BIFMA certified, tested PFAS-free, and rated to 330 pounds.

What's in the box. The seat, gas lift and base, plus the hardware and instructions to put them together in a few minutes. At 18 pounds the finished stool lifts easily, so it follows you from the desk to the kitchen island to whichever corner has the light. Designed in Boston and backed by a 7-year limited warranty.
