Given the age of many original Eames fibreglass shell chairs, replacing old shock mounts on the chair base is often required. Replacing shock mounts requires careful preparation and observation, but the result will mean your shell or DCM chairs are good for use for years to come.

Remove the existing rubber shock mount and clean the shell base thoroughly using a Stanley knife and sandpaper. Old shock mounts can crumble and break, so there is likely to be shock mount and adhesive residue on the fibreglass chair base or wood dining chair back. Clean the new replacement shock mount so it is free of grease and residue.
Lightly sand the circular face of the surface that will receive each shock mount to increase the adhesion. On the curved underside of a fibreglass shell chair there are flat circles that indicate the correct locations for the shock mounts in a H base configuration.
Mix the two part epoxy by squeezing a small amount out of the syringe onto a piece of cardboard and stirring it thoroughly with a disposable utensil. The epoxy hardens in minutes so it is important to work quickly.
Apply a layer of epoxy on the surface of the shock mount to be adhered. Use the utensil to smooth the epoxy out evenly, with coverage of at least 1/8 inch. Apply a layer of epoxy to the centre of the circular area on the shell chair base.
Place the shock mount carefully over the shell base location and press down gently. Look for the epoxy to ooze out around the perimeter of the shock mount. A small, even perimeter of epoxy should be visible, otherwise you may not have applied enough epoxy and the shock mount may not be stable when it dries. If this is the case, repeat step 4.
Wait for the epoxy to harden for a least a few hours or as per the epoxy manufacturer's instructions before installing the shell chair base and using it.
Tips and warnings
- Always follow the manufacturer's recommendations in using epoxy.
