A familiar outline hides the useful detail
Penshurst looks immediately understandable as a wing chair. The high back turns out at the sides, the arms form a sheltered sitting place, and upholstery softens the whole outline. Parker Knoll’s current model keeps that traditional furniture vocabulary in view.1
The technical interest lies lower down. Beneath the cushion, the maker uses its tension-spring system. That hidden arrangement belongs to a different story from the wings and fabric: one about how an upholstered chair supports the person sitting in it without relying on a deep box of large coil springs.2
The spring is below the cushion
Parker Knoll’s account credits Willi Knoll with developing a steel-wire tension-spring approach. It describes how reducing the bulky spring structure could allow a shallower upholstered base and more visible space below the seat.2
This distinction helps explain the object. A cushion changes how the body meets the chair. The support underneath determines what the cushion rests upon and how the seat assembly responds. Both contribute to the experience, but they are not the same component.
That organised underside is easy to forget once the cushion is in place. Yet it helps determine the depth of the upholstered base and the space visible below it. A traditional-looking armchair can therefore contain a production idea that changes its proportions as well as its hidden construction.

A company story, and one surviving chair
The manufacturer places the Parker and Knoll partnership’s public launch at the British Industries Fair in February 1931. That establishes a company milestone and the setting for the spring system’s British history. It does not, by itself, supply a birthday for every later Parker Knoll model.2
A much more specific account appears in the firm’s 2019 story about an apprentice restoring a Penshurst. The frame carried a 1966 date, and the project fitted it with new William Morris-patterned upholstery. Here the evidence belongs to one chair: a dated structure receiving another surface more than half a century later.3
That is a particularly readable piece of furniture history. The pattern seen after restoration expresses the newer upholstery choice, while the frame keeps its earlier date. The chair contains both moments at once.
The outline survives a change of clothes
An upholstered chair can change the mood of a room through fabric alone. A quiet colour draws attention to the wings and arms; a busy pattern can become the first thing the eye notices. Penshurst’s underlying shape remains available beneath either treatment.
The continuing model is interesting for that combination of visible tradition and concealed technique. Look at the winged back, then imagine the separate jobs below it: cushion, spring support and frame. The familiar armchair becomes easier to understand as an assembly whose soft appearance is only the outermost part.
