A kneeling chair is designed to shift the body weight onto the shins thus relieving the stress put on the lower back. Its use is recommended for people who suffer from back or tailbone pain. It was originally designed for seamstresses who would sit in the same position for hours, but is now used by a variety of people in different situations. Making one at home can be a complicated task and requires a lot of work on individual pieces before construction.

Things you need
- 5cm thick board of hardwood
- Ruler or tape measure
- Saw (preferably table saw)
- Electric drill
- Locking nuts
- Wood glue
- 10mm drill bit
- Phillips screw drill bit
- 3cm thick dowel
Cut a piece of hardwood 41cm square using a hand saw or table saw and round off the edges with some sandpaper.
Mark in pencil a rectangle 7cm wide and 16cm long 8.5cm in from one end in the centre of the board on the underside of the chair.
Cut a semicircular piece of wood with a radius of 8cm and thickness of 7cm. You may need to laminate the wood to achieve this thickness by gluing thinner slices of wood together. To laminate, cut the board in half through the middle to create two 2.5cm pieces. Sand down one to 2cm thickness and glue to a 5cm thick piece.
Drill a hole in the centre of the semicircle and glue to the underside of the seat in the rectangle marked out in step 2. The size of the hole depends on the type of bolts used. A 10mm bolt is sufficient.
Sand and varnish the sitting seat for the chair. Use a fine grain sandpaper to remove any rough edges and smooth corners and apply a layer of varnish using a paintbrush.
The Sitting Seat
Cut a piece of wood 45cm-by-26cm with a hand saw or table saw and round off the edges with some sandpaper.
Mark out a centre line on the long side of the kneeling seat made in step 1 and drill a hole at 15cm and 5cm from the edge.
Sand and varnish the kneeling seat. Remove any rough edges or splinters with a fine grade sandpaper and apply varnish using a paintbrush.
The Kneeling Seat
Cut out three 5cm wide pieces of wood, one 54cm long and the others 64cm long, a 20cm by 5cm piece of wood and an 18cm by 5cm piece of wood.
Cut a 45-degree angle off one end of the 20cm piece and on both ends of the 18cm piece. The 18cm piece should look like the base of a pyramid.
Drill 10mm holes in both 64cm long 5cm square pieces at 2.5cm and 8.5cm from one end and 27cm from the other.
Sandwich the two angled pieces between the 54cm rods. Glue the one angled at one end at the base with the angle facing up and the other 14cm from the other end.
Attach the 54cm long H shape constructed in step 4 to the 64cm long rod using screws. Attach the H with the angled piece closest to the longer rod. This piece should now represent a T shape.
Sand and varnish the sitting seat support.
Sitting Seat Support
Cut out two 5cm square pieces of wood, one 70cm long and the other 54cm long.
Drill holes in the 70cm long rod at 6cm and 16cm from one end.
Drill another hole 25cm from the same end though the wood on the other side of the wood.
Drill three 3cm holes from the other end of the rod at 15cm, 22cm and 29cm. These holes should only go about 1cm into the wood as these are used to make the chair adjustable.
Sand and varnish the wood for the kneeling seat support.
The Kneeling Seat Support
Get a piece of round dowel 30cm long and 3cm in diameter.
Drill a hole 3cm from one end.
Sand and varnish the adjusting rod.
The Adjusting Rod
Arrange the supports so the horizontal bars are flat on the floor. These act as support for the rest of the chair.
Run a bolt through the pre-drilled hole where these two meet and secure with a nut.
Attach the kneeling seat to the kneeling support through the pre-drilled holes with screws.
Attach the sitting seat to the support using a bolt through the H of the support and the semicircle piece. Use the screw hole nearest to the end of the support.
Screw on the adjustable rod to the second hole from the end on the seating seat support and select which hole it will fit in best for you in the kneeling seat support.
Fit cushions to both the sitting and kneeling seat.
