Solid wood, plywood, and engineered wood components form a full size platform bed frame that resists wobble and supports up to 600 lbs for consistent nightly use. Sturdy plywood slats distribute weight evenly across the 75 x 54 in sleeping surface so your mattress stays supported without a box spring. An embedded platform surface seats the mattress inside the frame to help reduce shifting. The 12-in height off the ground creates open underbed space that accommodates storage bins and allows robot vacuums to pass through easily.
