An easy desk chair design to get you rolling into your work day!  See how this one hour build can change your perspective on what's possible with our product.

Step 1:
Prepping your wood

After some research I found that a 17"x17" seat would be ideal for me.  I like to do the occasional easy pose while working, you know, like a real American, desk yogi. So I measured and cut a square in the dimensions aforementioned.  Then I drew out rounded edges on the two back corners of the seat.  I used a 12" record as a stencil.  I cut the rounded edges with a jigsaw. Now to measure and cut the lower lumbar support.  I wanted this piece to have the same dimensions as the legs, so I measured 14" x 3" and made my cuts. 

Step 2:
Sanding your wood

I wanted the birch ply to really stand out, so I carefully sanded the entire seat. I smoothed all the edges, especially where the back of the knees sit for comfort. Did the same with chair back. I paid extra attention to the top edge where my back touched, perfect for the occasional reach for the sky stretch. I sanded with 80, 120 and ended with 220 grit sandpaper. You don't want to over do it, but you'll be pleased if you take your time and get lost in your intention. Tip: to sand evenly, use a pencil to lightly scribble over the area that needs sanding. Once all the markings are gone, you should be good!

Step 3:
Adding a finish

Once your wood is sanded and ready, give it a wipe and prepare for finishing.  For this part I went with Osmo clear matte finish.  This was my first time using and it was a breeze, very pleased.  I evenly applied one coat with a 3" roll foam applicator.  I let it sit for about 5 minutes and then wiped off the excess using a soft rag.  The results were great!  Not too dark, just enough contrast to make those natural wood tones and markings pop.

Step 4:
Attaching your Bent Shelf Brackets

The aha moment came when I realized I could use our bent shelf bracket to attach a chair back to the seat :)  As silly as it sounds, it somehow works out great. I used two of the  4" x 7.75" Bent shelf bracket with a lip.( I'll eventually try this same technique in making a couch.)  I needed the brackets to be exactly one inch apart so I could use the unused screw holes to attach our cabinet handle. The chair is heavy, so the handle is, well, handy.  Before putting the brackets on I stuck some Scotch 1" square felt pads directly on the brackets over the screw holes.  I figured these would soften the blow of friction between the bracket and the seat. I did the same with the chair back. I attached the brackets with  1" wood screws.  I then attached the black cabinet handle to the unused holes for easy lifting.

Step 5:
Attach your 3x1 Single table legs

I really like how you can change up the orientation of the 3 x 1 single table legs.  The front legs I have sitting at an angle and the back legs perpendicular to the front of the chair, like the number 11, which resembles the brackets.  Placement was key to get an edgy, functional look going.  I attached the legs with 3/4" wood screws.  Now you can add your casters and you're done!  

Step 6:
Enjoy your new Easy Desk Chair.

This is certainly a concept piece.  But as I write this, I'm sitting on my easy chair and enjoying it. It's on roller blade wheels!! Beyond that, I appreciate body awareness, maintaining good posture and this chair helps to keep me upright.  Making a chair is no easy task, but with semi exact components, it certainly made it easier.  I'm proud of most things I create, but this little guy is pretty special.  I hope you enjoyed this tutorial and your new chair.
