Abstract
A foam material body for a bed, particularly a mattress, has a body part with a plurality of channels each having two deep channel portions located at opposite sides of a transverse plane of symmetry of the channel, and two narrow channel portions each extending from a respective one of the deep channel portions of the same channel. Each of the channels may have a maximum cross sectional dimension in direction parallel to supporting surfaces which is greater than a maximum cross sectional dimension of each of the deep channel portions in direction normal to the supporting surfaces. Each of the deep channel portions can increase in direction away from the middle channel portion of each channel, so that web-like sections formed between two channels of each pair extend toward the middle channel portion of the respective channel.
