Summary

Fumie Shibata's ITOKI work chair that reclines and slides its seat forward on its own as you lean back.

Best for

  • People who want the chair to move with them instead of setting many controls.
  • Small rooms; ITOKI lists it at 570 mm wide and 11.6 kg.
  • Choosing a base; it comes with casters or as a four-leg swivel chair.

Good to check first

  • ITOKI lists no weight rating, so ask the seller if it matters to you.
  • Seat height runs 425–540 mm on the caster model; check it against your desk.
  • Pick nylon casters for carpet or urethane casters for hard floors.

The trade-off

Automatic movement with few controls, and few published specs beyond size and seat height.

What ITOKI highlights

  • Linked recline

    Leaning back moves two linked pivots, at the arms and the back. The chair reclines up to 25° without a tension setting.

  • Seat that slides forward

    As you recline, the seat slides forward by up to 30 mm. ITOKI says the mechanism guides you toward a good sitting posture.

  • Flexing front edge

    The front of the seat flexes and tilts forward up to 10° when you lean in to work.

  • Base choices

    It comes with a five-leg caster base, or as a four-leg swivel chair with steel or wood legs. The caster model sets seat height with a dial under the right armrest.

As described by ITOKI on its official pages; not a Chairpedia assessment.
