Exhibitions: 19th-Century Modern

Thomas E. Warren’s “Centripetal Spring” chair is the forerunner of Don Chadwick and Bill Stumpf’s Aeron chair, designed nearly 150 years later. Both are made principally of metal, raised on casters for mobility, rotate on a central column, and allow for adjustment of the angle of the seat. Although Warren’s chair bears a patent mark (on the bottom of the seat), he felt the need to mitigate the newness of his invention by concealing its ingenious metal spring system beneath a dense, soft curtain of luxurious passementerie (elaborate trim). Similarly, he disguised his progressive use of cast iron for the frame by rendering it in the backward-looking Rococo Revival style and gilding it.
