Tools and materials
Stapler and staples, screwdriver and pincers, tacks and hammer, scissors and knife, measuring tape, raw cotton, kapok or cotton padding, upholstering material and tape, rope or braid.

Removing the old filling and restoring
- Remove the old upholstering and padding if they are in bad condition. Remove the tacks with a screwdriver and ensure you do not damage the wood. You can also do this using the pincers.
- Now is the time to restore the base of the seat using the leather strips or straps that support the structure and padding.
- These resistant materials can be firmly fastened using the tacks or staples.

Placing the new filling
- Measure the seat and try a piece of the new filling. This can be of raw cotton, kapok or padded with cotton cushions.
- Cut into size with the knife or scissors. If the filling is very thick you should cut it down to size to ensure it is even.
- If the cushion remains in good condition, you can cover it with a 1 centimetre thick layer of kabok material, leaving around five centimetres around the edges.

The upholstering material
- Cut the upholstering material, leaving five centimetres extra.
- Place in on the centre of the chair or however you wish, depending on the design of the material.
- As you place it, tack or staple it into place, without nailing it completely.
- Stretch the material and press firmly around the edges, stapling underneath the chair's wooden structure. It is advisable to fold the material slightly to staple it more firmly.
- Cut the material if necessary, although it can later be hidden.
- The tricky bits such as the back of the chair and the joint of the legs are solved by cutting the material and later folding it. Here you can replace the staples with decorative tacks.

Finishing it off
- If you wish, you can cover the seat with a material that hides all the edges and staples that keep the upholstering in place. Always ensure that you leave a margin of around two centimetres. It is also best to staple this material into place, folding it inside to reinforce the edges.
- If the material has not been fastened underneath but on the wood at the front, it can be hidden with a braid or rope of the desired width. This is stuck on with white glue or any other adhesive that does not damage the material or seep through.
