EAMES type Plycraft Replacement Tips

EAMES type Plycraft Replacement Mechanisms

Plycraft, a manufacturer no longer in business was a copycat reproducer of the famous Herman Miller Eames Lounge chair. Over the years, Plycraft used many different style mechanisms. We have found several styles to replace broken mechanisms. But none as easily installed and so low in cost as our style #402, which will replace any of the various mechanisms which Plycraft and others used. Adapting will always be required.

The original mechanism is seen on the seat cushion. This chair mechanism has a 1" dia. spindle making the original base usable when the mechanism was replaced.


This original mechanism instead used a wooden wedge to set the tilt angle. It has a 5/8" dia. spindle and there is not an available replacement. The mechanism and base must both be replaced if either the base or mechanism is replaced as shown in photo at right.


Style #402 replaced the original wedge mechanism shown on left. Notice wedge combined with mounting board for this particular client.



Obsolete Plycraft Mechanisms like these are not available
These mechanisms are replaced by #402 although the spindle is now shorter.



General Mechanism Installation:

The outside leather covering is easily removed by removing small screws with washers (washers available from Ace Hardware) from the wood underside. This will expose the molded wood inside bottom. Install the new mechanism using either method.

Installing the mechanism

A recommended method to eliminate unwanted or unnecessary drilling of holes and installing Tee nuts is as follows.
