Constructed from high-precision steel rods with a chrome finish, the X-Line Chair’s industrial aesthetic strongly reflects the high-tech movement of the time. The base’s innovative X-structure provides a sturdy foundation as well as a contemporary accent.
Available in a range of striking colourways, the X-Line Chair’s minimalist, logical design language remains just as relevant today, making it a versatile seating solution for a variety of home, professional and dining settings. Stackable up to 10 pieces, the chairs can be neatly nested to maximise space efficiency when not in use.

Niels Jørgen Haugesen was a leading Danish designer who embarked on his professional career under the tutelage of Arne Jacobsen, one of the most visionary architects and designers of the time.
Motivated by honesty and humility, Niels Jørgen Haugesen’s focus was more on utility than aesthetic or ornamentation, leading to minimalistic designs, clean forms and structural clarity. Haugesen designed the iconic X-Line Chair in 1977, relaunched by HAY in 2025.
