Kofod Larsen Lounge Chair ?
This chair is designed by Lawrence Peabody; part of the Danish Line by Selig.
Link to further information which shows the chair is NOT by Ib Kofod Larsen
I have edited this post as I gave completely incorrect info earlier today. Apologies.
Knowledge shared is Knowledge gained
One of the extremely rare cases of an American designing furniture in the 1950's, which was made in Denmark. While the primary intent of these designs was for import back to the U.S., somehow five of his chairs (four slipper chairs and the OP's chair above) were included in a 1955 exhibition at Charlottenborg, along with furniture by Wegner, Mogensen, Wanscher, and Kofod Larsen.
Quite the coup by Lawrence to be exhibited with those four.
