Herman Miller Eames Molded Plastic Armchair with 4-Leg Base
designed by Charles and Ray Eames

At A Glance: The Eames Molded Plastic Armchair is a bigger, more comfortable version of the classic Molded Plastic Side Chair. While you've often seen the side chair in school rooms and auditoriums, this model is a bit more substantial and supportive. Using revolutionary molding techniques, a series of different bases and their own renowned creative power, the Eames produced yet another classic with this beautiful variation.

What's To Like: The pedigree, the comfort, and the many different base options. Just having a piece of furniture designed by Charles and Ray is a thrill, but one that's especially comfortable and creatively accomplished is something of a coup. Comfortable and stylish - the cornerstones of modern design.

What's Not to Like: There is practically no give in the molded plastic, so attempting to use this chair as a recliner might not be a good idea. This is also not a great office chair - the back doesn't ventilate well, so after long hours of sitting there can be heat buildup.

The Bottom Line: A great twist on a classic, designed by the folks who made the original! Comfy, lovely, and full of color.

Molded Plastic Armchair

Landmark Design
Organic shapes. A clean, simple form sculpted to fit the body; first presented at the Museum of Modern Art in 1948.

Popular today. The chairs have achieved a pervasive presence that proves the staying power of good design.

Thoughtful Engineering
Friendly to the earth. Shells are recyclable polypropylene.

Integral color. The shell of the DAX Chair is dyed throughout so colors remain vibrant even after years of hard use.

Cushioned contact. For extended comfort, the shell is connected to the base by rubber shock mounts.

Glide options. The standard glide is also available with felt to protect hard-surface floors.

New Materials
New materials, especially those that held promise for doing more with less, fascinated Charles and Ray Eames throughout their careers. Their fascination led to inventive modern furniture, such as the molded plastic chair. Designed in 1948, it was the first plastic chair to be mass produced.

The current models looks exactly the same as the originals. They remain unupholstered, in keeping with the Eameses requirement that materials be expressed honestly and unselfconsciously. In fact, these were the first one-piece plastic chairs to be left uncovered.

At the same time, the chairs are better than ever. For example, the shell is now manufactured using more environmentally friendly, high-impact plastic.

This is the most simple variation in the series. Four metal legs, elegantly tapered and polished, with strong connections to the base of the chair and ends that keep the chair from sliding or leaving marks on wood and tile flooring. This is the model that you see most often in auditoriums and large gathering spaces. They're simple, lovely, and easy to deploy, stack, and use. That's right, each of these chairs can be stacked or ganged, making them convenient for spaces that are multi-purpose. When you need space, you stack up the chairs and put them to the side. When you need people to sit, you deploy them. These chairs are more than just seating; they're seating solutions.

The Four Legged style is the most common because it is the most simple and has the least amount of aesthetic flourishing in the legs. It's brother and sister chairs are more outgoing in the that regard, more showy of their beautiful designs. Because it always gets the job done, it's easy to move and manipulate in large groups, and it's more reserved style never threatens to clash with the tone of a room or a design scheme, this is a very very popular model of the Eames Molded Plastic Chair.
