How to use the two-step stool (11/14 cm)? Setting the chair height and foot position

Footrests are used when the chair height has been adjusted to the desk, but the feet are not yet firmly on the ground. It should not push the knees too high or block the chair legs.

First, adjust the chair height to suit your hands

Relax your shoulders, keep your elbows close to your sides, and then observe if your feet are dangling; do not lower the chair too much just for your feet.

Test 11 cm and 14 cm step by step

Start with the lower level and ensure your thighs are not pressed against the edge of the seat; only move to the other level if you need it to be higher.

The footrest position should allow movement

Place it where your feet naturally fall and leave room to change your foot position. Too close will bend your knees, and too far will require you to stretch your legs to reach it.

Check chair legs and aisle

The footrest should not get stuck between the chair wheels or become a tripping hazard when getting up, and the ground should remain stable.

  • Full foot contact
  • No localized pressure on thighs
  • Easy to move
HomeWorker Reminder

A sitting posture does not need to be fixed; the footrest should help stabilize while allowing you to naturally change foot positions and get up regularly.
