It is a variation on the Ant Chair, also designed by Arne Jacobsen.

It can come equipped with armrests, a writing-table attachment, and different forms of upholstering.

The chair is widely believed to have been used in Lewis Morley's iconic 1963 photograph of Christine Keeler; however, the chair used in this photograph was an imitation and not an original Jacobsen model.

[2][3] The Keeler chair had a hand hold cut in the back.

After the publishing of the pictures, sales of the chair rose dramatically.
