  • Hardwood

    Solid Mahogany Hardwood Sourced from Indonesia

    This collection is built from 100% solid mahogany hardwood sourced from Indonesia — real hardwood construction with a naturally rich tone and a smooth, refined grain. No MDF or particle board; just solid wood chosen for lasting presence and long-term use.

  • Renewable materials

    Responsibly Sourced Indonesian Mahogany

    Mahogany from Indonesia is typically supplied through managed forestry programs designed to support ongoing regrowth and long-term forest productivity. Choosing solid mahogany is a practical move away from short-lived composites and “fast furniture” materials, favoring a renewable hardwood built for longevity.

  • Eco-conscious

    Low-Waste, Long-Life Craftsmanship

    Our build approach focuses on getting the most out of every board: efficient cut planning, precise joinery, and real hardwood surfaces instead of veneer-wrapped cores. Scraps are repurposed when possible, packaging is reused or recycled, and the end result is furniture designed to last for decades rather than be replaced.

How much clearance is there under the frame?

The frame has a clearance of 4 inches from the floor, allowing some space for cleaning or low-profile storage.
