  • Ergonomic kneeling design promotes upright spine alignment and reduces back strain
  • Height adjustable from 21" to 31" for a personalised fit

Ergonomic Kneeling Chair with Back Support

The Dragonn kneeling chair promotes an upright posture by distributing weight through the buttocks and legs while keeping the spine aligned. It suits home offices, classrooms and professional workspaces where prolonged sitting causes discomfort. Users should acclimate gradually because different muscles are engaged compared with a conventional chair.

Height Adjustable Metal Frame

The strong metal base adjusts from 21 to 31 inches high and supports up to 250 lbs. A three‑inch mesh cushion measuring 16 by 13 inches provides firm support, while the knee rest measures 17.6 by 9 inches. The fixed seat angle is 90 degrees and the back support rises 10.5 inches above the cushion.

Upgrade from Standard Office Seating

This chair replaces a traditional flat seat when the goal is to reduce lower‑back strain and encourage active sitting. The jump is worth it for anyone who wants a simple, height‑adjustable kneeling option with integrated back support. It is not for buyers who need a reclining mechanism, armrests or a fully padded seat pan.

Questions about this item

How do I assemble the chair and which step causes the most trouble?

The chair arrives in several pieces with a metal X-frame, seat cushion, knee rest and back support. The step most people miss is tightening all bolts only after you have set the height between 21 and 31 inches; pre-tightening makes the height adjustment jam.

What parts will wear out first and need replacing?

The 3-inch mesh cushions on the 16 by 13 inch seat and the 17.6 by 9 inch knee rest compress over time. The metal frame and height mechanism are rated for the full 250 lb capacity and rarely need service.

At what point does the chair stop staying at my chosen height during a long day?

The pneumatic lift holds positions from 21 to 31 inches. If you exceed the 250 lb limit or the cylinder seal wears, the seat will slowly sink — that is the first limit you hit under sustained use.
