Abstract
A foldable foam mat has a longitudinal fold line extending over the entire length of the foam mat and a plurality of transverse fold lines which are arranged in pairs and extend, perpendicular to the longitudinal fold line, over half of the mat toward the edges of the mat. One of each of the transverse fold lines, which are arranged in pairs, is configured as a single fold line, and one as a double fold line. Preferably, the fold lines have an asymmetric configuration, referring to the cross section of the foam mat.
