Do I need a box spring with this mattress?

No box spring is required. The Estate Hybrid 14-inch needs a flat, firm, fully supportive base, which can be a platform bed, a slatted frame with closely spaced slats, a solid foundation, or a compatible adjustable base. Using a saggy or under-supported base can affect comfort and may affect warranty coverage, so make sure the surface properly supports the whole mattress.
