The MP-61 series marks the first instance in which Percival Lafer employed a fully visible fiberglass shell. Molded for efficiency and structural precision, the shell allowed greater formal freedom while simplifying production.

Foam upholstery rests directly on the fiberglass body, supported by a veneered plywood base. The result is a technically concise system that combines industrial thinking with comfort: a characteristic example of Lafer’s pragmatic modernism.
