This story began almost a year ago when I found this Tendo Mokko Heron rocking chair at a garage sale in Palo Alto. Many, many hours of work later – and after a significant financial investment – it joins the clan!
The last time I posted on this project was in December of 2012, at which time I discussed the damage to and repair of the right frame. Soon thereafter, I removed the tired vinyl and foam upholstery, which looked something like this:

The upholstery material at the front of the seat is sewn to a foam and muslin backing with pleats at about a 3″ spacing.

Both the upholstery and straps are fastened to the frame with upholstery staples – hundreds of them.

The seat frame is constructed in much the same way as the leg and arm frames. Note the delamination on the right side of seat frame.
With the upholstery removed, it became evident that the seat frame exhibit damage similar to that of the adjacent leg and arm frame, and it was repaired in much the same way. For additional strength, I drilled five .25″-diameter bores at 1.5″ spacing normal to and fully through the laminations along the apex of the seat bottom/seat back curve. At the openings on each side of the .25″-diameter bores I create a .5″ -deep, .5″-diameter cone with a countersinking bit. To help you visualize this, I effectively created five hourglass-shaped holes that ran from the back of the seat frame to the front of the seat frame at a spacing of 1.5″. Finally, I filled these with epoxy that, as it cured, squeezed and held the laminations tight. Considering the cost to reupholster this chair, I was taking no chances that this would fail again.
With the delaminated area repaired, I removed the old dark finish, epoxied the right armrest back in place, and sanded the arm and leg frames up to 400grit to prepare them for finishing. For this project, I chose Miniwax Antique Oil Finish. Like the Watco finishes, it is a linseed-based finish cut with mineral spirits and with some other “proprietary” ingredients. Frankly, I’m not particularly impressed with this finish, but with four coats and light sanding between coats, it built up a suitable thickness that I anticipate will be durable for a long time. I also like the smooth satin finish that this finish provides.

You’ll note here that the not-so-stock holes at each end of the armrest remain but have been ‘filled’ with brass countersunk wood screws that match those used to join the frames to the seat. After several attempts to fill and color match the holes, this ended up being the most visually satisfying solution.
In the meantime, Cam and I searched around for an upholsterer to complete the job. This is where things really get nuts: we received quotes ranging from $400 to $950 for the work alone and not including leather, foam, straps, and other materials. With suitable hides ranging from $200 to $400, you can understand how my $24 garage sale find was feeling less and less like a deal. We ended up choosing an upholster somewhere between the two ends of the spectrum - incidentally, he also upholstered our Saarinen Grasshopper chair. We chose a semi-aniline sage-green hide from S.H. Frank & Co. in SF to compliment the new satin finish. All in all, considering the amount of time that I have in this chair and upholstery costs, I probably should have just bought one from a dealer in the area. But then again, there are not too many in leather, much less this color scheme.

The leather shows a lot of grain and is very interesting in person. (That black spot is just dirt on my camera lens.)
I guess it would be prudent to finish with an assessment of how well this thing sits. With new, soft foam it is surprisingly plush, and the curve of the seat back and the angle of the seat bottom fit the body’s contour well. We’ve been using it with an Eames 671 ottoman, which makes rocking and long-term sitting more comfortable, but it sits well on its own as a conversational chair. Now we just need to find room in the house for it!
