A kneeling chair might not look very comfortable, but if you have ever used one you know it's perfect for sitting at a computer desk. It give you better posture by forcing you to sit up straight. It's better for your back than most conventional chairs. And while it might take a few days to get used to it, afterward you'll wonder how you ever got along without one. The simplest way to build your own kneeling chair is to start by taking apart an old wooden office chair.

Skill level:

  1. 1

    Use the saw to cut two pieces of wood 50mm x 65mm x 40cm. These will be the feet of the chair.

  2. 2

    Cut one piece of wood 50mm x 65mm x 60cm and two pieces 50mm x 50mm x 60cm. These will be the struts of the chair.

  3. 3

    Make an X with the three 60cm pieces of wood. Place the two thinner pieces on the outside, intersecting with the thick piece of the inside. Make the X about two-thirds of the way along the length of the planks, but the actual dimensions will depend on the length of your legs. Play around with it until you get the height right.

  4. 4

    Once you're sure about the height, use four screws to join the planks together at the intersection point.

  5. 5

    Use screws to attach the feet, one on each side at the bottom of the X, perpendicular to the struts. You will now have an X shape sitting on two feet. One side will be lower than the other.

  6. 6

    Use screws to attach the 10mm x 20cm x 20cm piece of wood to the struts on the side that is higher. Angle the wood so that it's pointing toward the lower end. This will be the seat.

  7. 7

    Use coach bolts to attach the padded seat on top.

  8. 8

    Use the screws to attach the backrest from the office chair to the struts on the lower end of the X. Angle it downward toward the opposite foot. This is the knee rest.

Tips and warnings

  • Sand the rough parts to give the wood a nice, smooth finish.
  • You will need to adjust the exact dimensions of the chair to fit your body size.
