Begin by cutting the hardwood pieces according to the dimensions of your desired sofa. The frame typically consists of a backrest, two arms, and a seat platform. Use mortise and tenon joints or strong wood glue and screws to assemble the frame. Ensure that the frame is square and sturdy as it will bear the weight of the entire sofa. Sand the frame smooth to avoid any rough edges that could damage the upholstery later.

Attach the webbing to the bottom of the seat platform. This provides the base support for the springs. Stretch the webbing tightly and staple it in place, creating a crisscross pattern. Then, install the coil springs. They should be evenly spaced and attached to the webbing using twine or clips. The springs will give the sofa its characteristic bounce and comfort.

Cut the foam padding to fit over the springs and seat platform. Use a combination of firm and soft foam to achieve the right balance of support and comfort. Glue the foam in place and then cover it with a layer of batting. This will help to smooth out any irregularities in the foam and give a plush feel.

For the arms and back, cut the upholstery fabric or leather to size, allowing for extra material to wrap around and staple underneath. Start by stapling the fabric at the bottom of the arm or back and work your way up, pulling the fabric taut as you go. Use upholstery nails to add decorative trim along the edges, if desired.

Place the seat cushion, which is also covered in fabric or leather, onto the seat platform. Staple the fabric underneath the platform, making sure it is smooth and wrinkle-free.

Inspect the entire sofa for any loose staples or fabric wrinkles. Trim any excess fabric. You can also add decorative buttons to the backrest and seat, which is a classic feature of Chesterfield sofas. These buttons are attached by pulling a thread through the fabric and foam and tying it off at the back.
