Abstract
A closed cell foam sleeping pad has a foldable configuration and can be folded accordion style. The sleeping pad's top and bottom surfaces have a plurality of protrusions and a plurality of indentations, wherein the protrusions and indentations are arranged at different locations on different but adjacent foldable sections of the sleeping pad body such that when the pad is folded accordion style, the protrusions nest into the indentations perfectly to give the sleeping pad a smaller packing density while at the same time providing the protrusions for added user comfort.
