Sinum Dining Chair w/ Swivel Base

The Sinum Dining Chair with Swivel Base introduces fluid movement to sophisticated dining spaces. Taking its name from the Latin word for "pocket," this refined chair combines compact proportions with generous comfort through its distinctive curved pocket of padding that embraces the sitter.

What distinguishes this version is its elegant swivel base in black powder-coated aluminum and steel, which adds a dynamic quality to the seating experience. The optional return mechanism ensures chairs remain properly positioned when not in use—an especially valuable feature in hospitality environments and conference settings where presentation matters.

Hamburg-based designers Birgit Hoffmann and Christoph Kahleyss have created a versatile piece that transcends traditional dining functionality. The chair's slightly tilted backrest and carefully engineered internal structure—featuring high-resilient, variable-density polyurethane foam—provide exceptional support for both active and relaxed seating positions during extended gatherings.

For spaces with different requirements, the Sinum collection offers additional options, including the armchair version of this swivel base design or models with casters for maximum mobility, while maintaining the same refined aesthetic and comfort characteristics across the entire range.
