K2 Lounge Chair Swivel by Plus Halle was designed by Busk + Hertzog — the Copenhagen design duo of Flemming Busk and Stephan Hertzog — whose furniture practice is known for a particularly effective synthesis of ergonomic quality and formal refinement. The K2 is a high-back lounge chair with a swivel base, designed to provide full-body support — including head and neck support through the high back — while the 360° swivel allows the chair's orientation to be adjusted without repositioning it on the floor. The high back creates a notable degree of acoustic and visual enclosure, making the K2 particularly valuable in open-plan office lounge zones and public waiting spaces where privacy within a shared environment is a design objective.

The K2 Swivel's high back sets it apart from conventional lounge chairs in both functional and formal terms. The additional back height provides genuine neck and head support during extended sitting — an important ergonomic detail for lounge chairs used in workplace and hospitality environments where users may sit for extended periods. The swivel base adds operational flexibility: users can turn to engage with different people or parts of a space without rising from the chair, which is particularly useful in reception, waiting and breakout environments. The chair is available in multiple upholstery options that allow specification across corporate and hospitality palettes.

Interior designers and architects specifying the K2 for office lounge, hospitality and waiting-area environments will find the DWG drawing and CAD block useful for furniture placement, zone-planning and clearance documentation. The 3D model and Revit family support BIM-accurate spatial coordination across workplace and hospitality project models. A well-engineered and formally refined specification for any project requiring a high-back swivel lounge chair combining ergonomic quality with contemporary Danish design.

Available as a 2D DWG drawing, 3D model and Revit file.
