Picture of Shock Mounts for Eames Fiberglass Chairs

This project came about after I picked up a few Eames fiberglass chairs that needed new mounts. The shock mounts on these chairs are often cracked and squished after 30+ years of use, or the glue has failed and they've fallen off.

If you already have shock mounts, skip to the last step of this Instructable for Installation tips. The remaining steps will show you how to make your own mounts.

Since I had 4 chairs that needed new mounts, making them myself was a lot cheaper than buying reproductions. There's no waiting for shipping, I can have the mounts the next day, and I can control the quality myself. Aside from the mold rubber, the only cost is the weld nuts ($1.63 each for Stainless Steel or $.74 each for Zinc Plated). Stainless weld nuts are an improvement over reproduction or even the original mounts, because they won't rust if the chairs are being used outdoors.


  • Precise Scale (to weigh out rubber and pigment)
  • Hot Glue Gun
  • 100% Silicone and a Caulk Gun
  • 1/8" Drill Bit (more or less)
  • Spray Adhesive like 3M Super 77
  • Razor Blade / Utility Knife / Scissors
  • Mixing Cups
  • Sticks for Mixing
  • Mold Release


  • Polyurethane Mold Rubber (like Polytek 75-60)
  • Weld Nut with Holes (Rotaloc) 1/4"-20 Zinc Plated or 1/4"-20 Stainless
  • Used Tube of Silicone (to make the round form)
  • 3/16" Washers
  • Black Pigment

Just so you know, the stainless will crevice corrode (http://en.wikipedia.org/wiki/Crevice_corrosion) in the rubber since there would be a lack of oxygen. There aren't a lot of other options though, so stainless will probably still be your best best (unless you fabricated fiberglass and epoxy composite "weld nets" yourself).

Loved this post. I wish I had one to restore. Thanks for sharing the process so plainly!

Thanks. Herman Miller in the US and Vitra in Europe made a lot of the fiberglass chairs. Your best bet is to look locally. Unfortunately in shops and on ebay, everyone asks a lot. But if you keep looking, they will find you ;)

How awesome is that?! I love learning more about how these sorts of things are restored. :)

Let's save the originals while we still can!

Beautiful work! The 'ible itself was very nicely presented. Both the textual content and the photos are remarkable. It's quite refreshing. Thanks.
