Active seating for ages 12-18

The VEVOR Harry400-N is a height-adjustable wobble stool designed for users aged 12 to 18. Its PVC and ABS seat swivels 360 degrees and tilts on a 150-degree gas lift. A TPR curved base grips the floor while supporting up to 105.8 lbs.

Replaces static classroom chairs

Swapping a fixed seat for this stool adds continuous micro-movement that helps reduce fidgeting and strengthen core muscles. The jump is worth it when a student struggles to stay seated during lessons or needs sensory input to maintain focus.

Check floor surface and user weight

Verify the floor is hard and level so the non-slip base can grip properly. Confirm the intended user weighs no more than 105.8 lbs and falls within the 12-18 age range. Ensure 13.0 inches of clear diameter is available for the base footprint.

Questions about this item

What floor space does the 13.0 in base need?

The chair sits on a 13.0 × 13.0 in footprint, so allow at least that much clear floor area plus room for the 360° swivel motion.

Which step of the gas-lift installation is most often missed?

Insert the gas lift fully into the base until it seats firmly, then press the seat cushion onto the lift until it locks — skipping either lock leaves the chair unstable.

When should the TPR non-slip base be replaced?

Replace the curved TPR base once the grip surface wears smooth or the material cracks, because the anti-tip stability depends on its floor traction.
