OMI has two types of mattress foundations made from earth friendly raw materials

• WOOD-SLAT FOUNDATIONS – the wood is made from untreated wood slats wrapped and padded in organic cotton canvas. Ideal for rubber mattresses, the wood foundation provides the extra firmness to the bed.
• 8″ BOX-SPRING FOUNDATION – built using springs and untreated wood slats, also covered in cotton canvas, the box spring foundation is great for soft and conforming support.
