    Product Details

    Made of wooden side rails, middle panel and slats, this foundation is covered in a durable 100% Polypropylene woven fabric. The slats are covered in non-skid fabric to prevent your mattress from sliding around.

    • Align locking blocks in each of the four corners.
    • Insert lock pins into each of the four locking blocks, pushing firmly to ensure proper alignment.
    • Line up each end of the center rail with the corresponding tapered slide connector and firmly push down into place, making sure the “Up Arrow” faces upward.
    • Start one end of each support slat pack against the head/food board, with the hook side facing down to firmly catch the loop material on each side rail. Unroll the slat packs toward the center fully extending them.
