THONET Three-seater sofa • S 5003 C001 programme
Building on the archetype of the minimalist sofa with a bent tubular steel base, which first became part of Thonet's portfolio in the 1930s, designer James Irvine developed a versatile, transformable furniture system in 2006. The S 5000 sofa programme is based on a simple, intelligent modular construction concept. Inspired by the growing convergence of work and living spaces, it was intelligently developed further in 2020 by Studio Irvine, fully in keeping with the vision of its founder James Irvine, so that it fits the modern context of New Work: depending on requirements, identical armrests and backrests, or partitions for visual and acoustic screening, can be integrated into the seat frame. This makes it extensively expandable, and thanks to variable side panels it also finds its place in multi-space office concepts. The panels form the frame for various cushions, which are simply placed on top. In addition, side tables can be fitted, connected to the sofa's tubular steel frame. In this way, entire sofa landscapes can be created that can be modularly extended and reconfigured. This means the S 5000 works as a classic sofa in modern living environments; in its smaller version with panels it serves as a smart-working station in the home office, and in a larger variant it suits areas such as central zones or lounges in office contexts, co-working spaces, or waiting areas. The programme is further extended by variants with castors.
The THONET S 5003 three-seater is a pre-configured combination from the modular S 5000 sofa programme: a tubular steel seat frame into which identical armrests and backrests are hung. In the version with low armrests, two low and three high upholstery elements sit in the frame; in the fully high version, five high upholstery elements. The frame is chrome-plated or black, and the upholstery is comfort upholstery. Plastic or felt glides are available for an additional charge.
