Shea Alexander designed this stool as the perfect stool to use at your workbench. This is the second stool in his stool-building series on his blog, Amidst The Shavings. Paid subscribers to his blog receive these plans for free, along with a guided series of build posts walking you through the build process and much more.  
These plans include elevation drawings, cut lists, and full-scale seat, leg, and rung patterns. 
This is a digital download. Printed paper copies are available HERE.

These plans are drawn by Matt Adams with proofreading by Shea and Jeff Lefkowitz.
