Castell Sofa

German designer and artist Hans Hopfer had a profound impact on furniture design that still guides the choices we make about our spaces today. Affectionately dubbed “seating landscapes,” Hopfer’s forward-looking collections of inviting, modular low-profile seating, such as the widely revered Mah Jong sofa for Roche Bobois, allowed for optimal customized arrangements in one’s living room, an innovation that reshaped relaxation at home in a significant and lasting way. 

Hopfer designed modern furniture for a manufacturer in Nuremberg during the 1960s. He met Phillippe Roche in 1970 and began his collaboration with the Roche Bobois company. When the popularity of cable television took hold in more major American cities during the 1970s, sofas and other seating became integral to contemporary living-room decor. Roche Bobois’s newly launched Les Contemporains series positioned its own sofas front and center, and it also offered plush lounge chairs designed by Mario Bellini.

Bold works from Roche Bobois during the decade included one of its most enduring and well-known pieces — the Mah Jong sectional sofa created by Hopfer in 1971. Anchored by few central elements, this modular lounge sofa can be combined or stacked, giving the buyer total freedom over its appearance and the ability to maximize comfort with its plump cushions. Inspired by a tile-based game that originated in China, the Mah Jong has been in production since its debut. It is still handmade in a workshop in Italy today. 

Composed of low seating elements and large cushions, Hopfer’s Mah Jong sofa has seen some high-profile fabric updates by Missoni, Jean Paul Gaultier and Japanese clothing designer Kenzo Takada, who worked with Roche Bobois to craft fabrics emblazoned with geometrically dynamic patterns to be used as upholstery for the firm’s iconic piece of furniture. 

Primarily a sculptor and painter by trade, Hopfer worked and lived between Buenos Aires, Nuremberg and Paris. In addition to the work he did for Roche Bobois — which included his Informel armchairs and sofas — he also created modular furniture for the Wiener Werkstatte, a collective of artists and designers born from the Vienna Secession art movement in Austria during the early 20th century.

An antique, new or vintage sectional sofa is a versatile and practical style of seating that makes for a great addition to your living space.

A traditional sofa is typically a long upholstered seat that features a back and arms and is intended for two or more people, whereas a sectional sofa consists of multiple pieces that can be arranged in several different layouts. While a conventional couch or sofa can definitely seat a fixed number of houseguests, sectional sofas allow for customizing. We all know that maximizing your square footage in a small space can prove difficult, so the modular characteristics of sectional sofas are especially appealing when you’re thinking about design ideas for your modest-sized living room. This furnishing can be arranged in a semicircle, an L-shape or other configuration and will seat more people than a standard sofa will.

When it comes to home decor, the trick is to find a balance between functionality and style. Sectional sofas are available in a wide variety of shapes, sizes, colors and fabric options, so you’re sure to find one that perfectly complements your interiors and needs. But there are several factors to consider when choosing the perfect sectional sofa for your space.

According to Charleston designer Angie Hranowsky, “the most important thing to know when choosing the perfect sofa is its purpose. Is it for conversation or for watching TV and lounging? Then you can determine the right depth and seat height.”

The size of your sectional sofa will depend on how much real estate you’re working with in your living room and exactly how you use the space. If you’re trying to define a common area in your sprawling loft apartment or you’ve got a large family to think about, a large, sleek contemporary sectional or sculptural sectional sofa designed by Milo Baughman, say, could be ideal for comfort as well as a conversation piece, particularly if you intend to entertain with regularity. Think about seat height and depth — high seats, for example, can yield an air of formality that might not be a great fit for your crowd.

For movie nights, holiday parties or the occasional but totally fabulous dinner party, a large sectional sofa means getting multiple uses out of a singular piece of seating. In smaller rooms, it might make sense to position your small sectional sofa against the wall, whereas in a wide-open space, the sofa’s components can occupy the center of the room. Measure accordingly and make sure your doorways can accommodate on delivery day.
