Art Deco Armchair by Alphonse Siebers, Netherlands, 1920s

This rare and characterful armchair, designed in the 1920s, exemplifies the Dutch Art Deco movement, particularly reflecting the Amsterdam School's influence. Crafted from solid oak, the chair showcases refined joinery and a distinctive openwork motif beneath the seat, highlighting the era's emphasis on geometric clarity and artisanal craftsmanship. The deep blue leather upholstery complements the chair's original proportions.

Peter Alphonsus Maria (Alphons) Siebers (Amsterdam, 15 September 1893 – Ulvenhout, 15 May 1978) was a Dutch architect and urban planner whose body of work bridges traditionalism and modernism. A graduate of the Technical University in Delft, Siebers became particularly known for his religious architecture, which in later decades was strongly influenced by the Bossche School - a movement rooted in liturgical clarity and proportional harmony. His designs are marked by a sensitivity to material, form, and meaning, ranging from expressive early works in the Amsterdam School style to sober, sacred spaces shaped by his evolving spiritual and architectural convictions.
