Hm105 Planar by Magnus Long.

Meet the hm105 Planar Chair by Magnus Long. Designed with clarity and built to last.

At its core are three simple elements: frame, arm, and upholstery. This thoughtful structure not only defines its look, but makes it easy to update, and extend the chair’s life over time.

The extended arms create a clean, continuous line while doubling as practical surfaces—for work, rest, or connection.

With a broad range of materials and finishes to choose from, Planar lets you explore colour and texture, so each chair feels perfectly suited to its space.

Developed through an ongoing collaboration between Magnus Long and Hitch Mylius, Planar is all about honest materials, purposeful design, and enduring appeal.
