This mattress foundation delivers stable, consistent under-support for an Eastern King size mattress, fitting neatly into most existing bed frames for standard bedroom setups. It features a solid internal jet black metal frame, wrapped in a textured 100% polyester fabric cover that keeps dust and debris away from your mattress base. The 8.5 inch high profile creates a solid elevated base that pairs well with most headboard and footboard combinations. Assembly is straightforward and can be completed quickly, with only the foundation included; mattress is sold separately.
