Abstract
Abstract A mattress construction comprising a filler with a surrounding mattress cover. The cover defines an opening along at least one of its ends, and a zipper is provided for closing the opening. A fabric section of the cover is positioned in overlapping relationship with one end of the zipper. This section defines a pocket for receipt of the zipper closure when the zipper is closed to thereby reduce the likelihood that the zipper will be opened during use of the mattress.
