There was a post on LJ of something similar to this quite a while back, but when I pm’d the LJ there was no reply. So, I went searching the internet and found this.

Elliptical chair

I sent this person an email to see if the plans or other information are available.

This is his description;

A new finger-end adjustable wood joint system is created to provide broader consumer group with comfortable and ergonomically correct products. The furniture designs that use this system are knock down, adjustable, easy to produce and suited for mass customization.

Manufacturing time: 20 minutes; Assembly time: 5 minutes.
Software: Sketch–Rhino- Master CAM – toolpaths-CNC: Thermwood router

Are you going to try this!? A router and a template should see you up and running. Should be a good seller in the urban market.

It doesn’t fit my patio theme, but I have my brother hooked bad. Hoping the designer responds with some of the details or a CAD file. Interesting that he only used a single 5’ by 5’ sheet, I would thing the elliptical sides are a big material eater. The knock down aspect isn’t important to me, but I like the adjustable concept.

Being this is October in Michigan, it won’t get too high on my list until next April. Then again…..
