Experiment 501 lounge chair

Green-light beige

The Experiment 501 lounge chair from Hem is an iconic armchair designed by Yrjö Kukkapuro. With its distinctive postmodern silhouette and expressive armrests, it blends sculptural form with ergonomic comfort. The construction showcases Kukkapuro’s meticulous attention to detail and provides support where needed, while the chair itself becomes a strong design element in the living room or reading nook. The Experiment 501 works equally well as a conversation chair or a relaxation piece and remains faithful to the original’s character while feeling perfectly natural in contemporary homes.
