Thoughtfully crafted to complement every Hypnos mattress, the Handcrafted Wood Foundation is built using premium SPF lumber selected by skilled Amish craftsmen. Each piece is hand-cut, carefully chosen, and kiln-dried to help prevent warping and cracking over time before being expertly assembled and upholstered by our team in Virginia. Reinforced beneath the sleeping surface for exceptional stability, the foundation provides the enduring support your mattress needs to perform beautifully for years to come.
