Crown Imperial Box Spring Foundation

Each Crown Imperial® foundation features a quilted surface. This beautiful aesthetic accent is a reminder of Kingsdown’s commitment to details and quality through every surface, every layer. Our solid wood framing is precision-milled by highly skilled craftsmen. Center and side rails are carefully built to balance the full weight of the mattress and sleeper for years of reliable support, while head and foot support rails are trimmed wider than industry standards to offer an even stronger edge support system.Each wooden slat is placed closer together and cut a full inch wider than most manufacturers to provide a sturdier base. This not only reduces motion and bounce, but also creates a more solid surface, which extends the life of the mattress. As a finishing touch, the corners of our foundations are protected with beautiful nickel-plated corner guards, embossed with the Kingsdown name.
