The DeLaval cow mattress M40SB is suitable to be installed in stanchion barns with free hanging dividers in order to obtain a continuous resting area for the cows. The high density wrapped foam as well as the reinforced rubber top cover will stand the permanently load exerted by the cows. In order to secure durability, the last 300mm of the top cover towards the gutter have been reinforced with a layer cured in the top pattern.
