Our wood-slat foundations are designed for optimal support and to perfectly complement your OMI mattress. Made with high-strength lumber, certified organic cotton, and wool, and featuring a built-in latex pad and brushed-canvas top panel to protect ‘flippable’ mattress models from excess wear. One-inch slat spacing ensures the proper support for all OMI mattress models, including the REST® collection. Optionally, for REST collection mattresses a supplemental foundation layer (SFL) may be used in place of a foundation. Contact us for details.
