No, Sealy mattresses should not be used with a traditional box spring, according to Sealy’s customer support. The company suggests using a flat, solid foundation.

If you choose not to purchase our foundation, you must position the mattress on a completely flat, solid surface with adequate center support.

For those who choose to purchase a Sealy foundation, they offer a low and high version for their standard foundation or an adjustable base.
