General Instructions

Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!


Step 1

Build the basic seat frame by attaching with the exterior wood screws or pocket holes. Use glue at joints (exterior rated). Check for square by measuring from opposite corners and adjusting so the two diagonals are exactly the same.

Step 2

Add legs, ensuring that the bottom of the legs are 28-1/2" apart.

Step 3

Screw back to tops of back legs with exterior wood screws.

Step 4

Add optional back support with screws from top and sides. Inset 1/4".

Step 5

Step 6

Attach the armless piece to the full sofas for optimal support.

Finishing Instructions
Preparation Instructions
Fill all holes with wood filler and let dry. Apply additional coats of wood filler as needed. When wood filler is completely dry, sand the project in the direction of the wood grain with 120 grit sandpaper. Vacuum sanded project to remove sanding residue. Remove all sanding residue on work surfaces as well. Wipe project clean with damp cloth.

It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.

Hi- we're getting ready to build this- and I have the same two questions the above people did: 1) are there any existing plans for the modified chaise? I can probably figure it out, but would love it if plans exist. and 2) any recommendations for cushion sourcing?
