Eames PSC-4 Chair, Eames PSCC-4 Chair

Quick Intro

What is an Eames PSC-4 or PSCC-4 Side Chair?

Well essentially it is the same as the PSC side chair, which stands for Pivot (P) side chair (S) on Cast Alu Base (C) and later PSCC version with added castors (C), however it’s the added variant number 4 which stands this design out from others.

The Eames PSC-4 Chair, part of the fiberglass series, has a unique design and appearance due to the factory-made duo of attached cushion and lumber support. This unusual addition added a new level of comfort, especially for the purpose of using the chair for work, whereby it could potentially be used for longer hours.

Although the same top has appeared over the years on other base types, it was always intended to be part of the PSC range and it is therefore likely these combinations arose from customization or simply changing bases. The only known possibility was during the 1960’s when it was also available as a DSX.

This variant of the PSC range didn’t arrive to market until much later and was only ever used on the later ‘2nd generation’ contract base post 1957. By the end of the 1950’s an adjustable height version of the PSC base arrived, and these variants added an A to the name, for example PSC-A-4.

By the time the Eames PSC-4 Side Chair and the Eames PSCC-4 Chair were available, the full range of colors of shells were available from Herman Miller, both domestic and contract though most do tend to have white or parchment.

Buying Tips and Authenticity

The PSC-4 top has never been copied as far as we can ascertain giving a very high chance of being authentic.
The top will have the same labels and stamps as all other Herman Miller shells.
The PSC base should be age appropriate and could have either glides or castors. There was only one generation of the PSC-4.
There are no other upholstery options other than the standard cushion and lumber pad already applied
The PSC-4 base could have either nylon self leveling floor glides or castor wheels.

The condition of the factory built-in cushions is paramount to the overall value.
Check the fiberglass shell for cracks, chips or bad repairs.
Ensure the cushions are attached in the original way and not via a repair
Check the cushions for sagging, fraying, cuts or rips and that the cushions sit flush and without movement
Most variants of the PSC-4 eames chair are white so alternative colors tend to hold higher rarity and value.
