Adirondack Chairs

I have built a number of the traditional slat back adirondack chairs in the past

and had been thinking of how I might change the design to make it more minimalist, 

simplify construction and decrease cost using modern alternatives to

traditional wood such as plywood or what have you.   I more or less had the design in

mind and was looking to see if I could find something like what I had imagined.

I was surprised to see the chairs below come right up from google as this was 

what I pretty much had in mind.  Turns out the chairs below are from 1905 

and recently sold for $6,600 to Annie Liebowitz.  Apparently the Adironack Museum in 

NY sells the plans. I'll have to check it out.  This particular style of chair is called a 

Westport chair after the town in Upstate NY.

Update:

Here is a link to the plans from the Adirondack Museum
