Kneeling chairs position you with an open hip angle.

Be sure to balance your torso forward of your hips in your kneeling chair. If you shift your torso backward you will slump.

Our recommendations
  • Some people can use a kneeling chair comfortably for computer work; others cannot. In fact, most cannot.
  • We recommend kneeling chairs for short-term tasks requiring forward reach or a fine hand-manipulative task, for example, writing with pen and paper, eating at a table, sewing.
  • We discourage the use of kneeling chairs for prolonged sitting, particularly if you are tall and cannot find a kneeling chair that accommodates your leg length.
Pros
  1. Kneeling chairs position you with an open hip angle. This eases your hips forward to encourage an upright posture, aligning your back, shoulders and neck.
  2. Kneeling chairs reduce low back or neck pain for some people.
  3. Kneeling chairs make forward-reaching tasks easier.
Cons
  1. Kneeling chairs confine your legs to one position, which can increase pressures under the knee cap and slow circulation to the legs.
  2. Kneeling chairs prevent you from using your feet to scoot around and navigate your work area.
  3. Kneeling chairs can be tricky to get in and out of.
How to fit a kneeling chair
  • Distance between seat and knee-pad. Kneeling chairs should offer enough leg room to allow you to get in and out easily, and to allow a comfortable amount of knee bend.

    Make sure your knee-bend is not forced to the max. Some folks have more knee-bend available (a.k.a. "knee flexion") than others. A good test is to see if you can still lift your lower shin-bone off the knee pad when you are in the chair.


    Most kneeling chairs on the market today (including those on our website) fit shorter folks best (i.e., under 5'9"). Taller folks find their legs are cramped in most kneeling chairs, which can produce pressures on the knees and impair circulation in the legs.

    Back in the 1970's there were kneeling chair available for taller people. Unfortunately, they didn't sell in sufficient numbers to support their manufacture, and they were pulled from the market.

  • Seat width. Your seat should be wider than your hips, to allow space for movement and clothing.

  • Seat angle. The greater the forward slope of the seat, the more erect your posture. We recommend a forward seat slope of at least 25°, but that can be hard to find.

  • Backrest option. Backrests are unnecessary on a properly fitted kneeling chair. The forward seat angle encourages an erect posture without a backrest.

  • Seat adjustments. In an ideal world, a kneeling chair would offer separate seat-height and seat-angle adjustment. In reality, few kneeling chairs offer much of either, and those that do combine seat-angle and seat-height adjustments (e.g., raising the seat also produces greater forward seat slope, and vise versa.

    Non-swivel kneeling chairs offer more adjustment in seat-slope and seat-to-knee distance than swivel models, but when you adjust the seat higher you also increase the seat slope.

    Taller folks usually fit non-swivel kneeling chairs better. Shorter folks can generally use either swivel or non-swivel models.

    In years past we had kneeling chairs that offered both swivel and seat-slope and seat-to-knee-distance adjustments. However, they didn't sell in sufficient numbers to support their manufacture and were discontinued by the manufacturer.

  • Swivel. If your kneeling chair does not swivel, make sure your work is positioned directly in front of you so you won't tweak your back trying to twist and reach.
