This is a chair that i recently constructed for a project, It is not exceptionally difficult to make. However it did take me some time.
What you will need:
Three inch screws
Optional: Jig kit
Create a template, this is not completely necessary, however I found it much easier to cut out the design that i wanted to cut the wood into once i created a plywood template. The template was made up of four pieces of plywood that came together into a type of crescent shape.
