Abstract: A mattress includes a mattress cover. The mattress cover has a first textile, a second textile, a zipper, and a fire-resistant textile wrap. The zipper connects the first textile to the second textile. The fire-resistant textile wrap covers at least a portion of the zipper. A portion of the first textile and the zipper define a seam. The seam is inwardly separated from an outer side surface of the mattress cover by the portion of the first textile.

Abstract: Bed systems include a mattress that is configured to be attached to a foundation. The bed systems include a strap and a connector configured to hold the strap and connect the mattress and the foundation to each other.

Abstract: A system can include a zipper that connects a mattress to a bed foundation. For example, the zipper can extend from a head end to a foot end of an adjustable foundation. For another example, a zipper can connect to a mattress along a seam of the mattress and/or to a foundation along a seam of a foundation. For another example, a first zipper can connect the mattress core to a second zipper and the second zipper can connect a foundation to the first zipper. For another example, first and second zippers can be substantially vertically aligned.
