Begin with the boards
The Crate Chair asks a practical question before an aesthetic one: how much furniture can ordinary boards provide? Gerrit Rietveld answered with a low, open armchair whose broad pieces remain easy to distinguish. The material, assembly and way of selling the chair belonged to the same idea. Centraal Museum dates his first crate furniture to 1934 and records that he supplied it either assembled or as a kit.1
Look at the broad faces and the spaces between them. A board can support the body, define an edge or connect other pieces. Those jobs remain visible. The chair does not need a continuous upholstered volume to make its place in a room understandable. Its silhouette includes a considerable amount of the room behind it.
A rough surface could belong
Design Museum places Crate in the difficult economic circumstances of the early 1930s. It describes inexpensive timber with visible flaws and a deliberately straightforward construction. The unevenness of ordinary wood was compatible with the design, rather than something that had to disappear beneath an elaborate finish.2
That changes how the eye reads the object. Grain, a knot and the width of a board can remain part of its character. The interesting comparison is between the regular arrangement and the irregular material. Repeated pieces give the chair an order; the timber keeps that order from looking perfectly anonymous.

Furniture for the weekend
In 1935 Metz & Co introduced a series of crate furniture as Weekend Furniture. Centraal Museum connects it with affordable furnishings for holiday homes. The kit option also moved part of the work beyond the workshop: the buyer could receive components rather than a finished chair.1
A kit makes the relationship between design and assembly unusually plain. The maker must resolve which parts belong together before someone else can put them together. Simplicity is therefore a task for the designer as well as a possible convenience for the customer. The documentary record supports that specific arrangement; it does not establish a universal first in flat-pack furniture.
The idea outlives one edition
The later Rietveld Originals and HAY collaboration brought the Crate series back into production. HAY identifies the connection with Rietveld's ambition for affordable, well-designed furniture. That is a manufacturer's account of the relaunch, rather than evidence that its present products are identical to every earlier chair.3
The useful way back to the original is through its parts. Follow a board, notice the job it performs, and then look at the open chair again. A modest piece of timber has become both a working component and a line in the room.
