1918, W. B. Maxwell, chapter 12, The Mirror and the Lamp:
- There were many wooden chairs for the bulk of his visitors, and two wicker armchairs with red cloth cushions for superior people. From the packing-cases had emerged some Indian clubs, […], and all these articles […] made a scattered and untidy decoration that Mrs. Clough assiduously dusted and greatly cherished.
- 1928: A. A. Milne, The House at Pooh Corner
- […] when he suddenly saw Piglet sitting in his best armchair he could only stand there rubbing his head and wondering whose house he was in.
