Description

Mason is a low-profile office chair that combines sculpted wood curves with generous cushioning and padded armrests. Wrapped in premium faux leather and finished with a distinctive wood structure, it brings a refined, furniture-inspired character to modern workspaces.

Features

  • A Distinctive Expression of the Mathias Design: Its low-back silhouette creates a lighter, more open feel while preserving the signature curves and balanced proportions of the Mathias collection.
  • Sculpted Wood Structure: The curved wood structure gives Mason a distinctive furniture-inspired look, while the soft upholstery adds a comfortable touch.
  • FSC® Certified Wood: We use FSC® certified wood, which ensures that our pieces are made sustainably, and the world's forest resources are used responsibly.
  • Premium Faux Leather: Premium faux leather upholstery offers a smooth, refined finish that complements the warmth of the curved wood structure.
  • Practical Adjustments, Effortlessly Integrated: Adjust the seat height by up to 3 1/8" and rotate 360° to suit your workspace. Unlock the recline function to lean back freely between 95° and 115°, or lock the chair in its upright position for focused work.
