The MP-61 Sofa, designed by Percival Lafer in 1973, is a notable piece of Brazilian mid-century furniture featuring a visible fiberglass shell structure with upholstery foam applied directly, without additional elements like elastic bands. It rests on a cross-arranged plywood base with rosewood veneer, combining elegant low-profile hardwood frames and plush leather. This innovative design balances craftsmanship and functionality while optimizing production efficiency.
