The present invention refers to an improvement in a bed mattress containing signal means for the identification of the correct mattress position for any day of the year, making it viable for the implementation of a rotation program designed for increasing the useful life of this product. The improved mattress contains signal means for indicating which one of the four possible mattress positions is the correct one at the date of inspection. For example, in a monthly rotation program, if the current month is not indicated on the mattress in a directly readable form, the mattress should have its position altered, until the correct month is directly readable on the mattress. In this manner, the four positions of the mattress are uniformly used, expanding significantly the useful life of the mattress, in comparison with another that is not rotated, that is rotated sporadically or that is rotated in a random fashion.
“MATTRESS IMPROVEMENT CONTAINING MEANS FOR ROTATION SIGNALLING”, in which the mattress is constructed of a core and a cover enveloping the core, characterized by means for rotation signalling, in which the said means indicate the correct position of the mattress in any day of the year, so that the use of the mattress can be divided in a controlled fashion in periods substancially equal for all the four possible mattress positions in relation to the bed, thus distributing in time and space the external factors that deform a mattress, therefore expanding the useful life of the mattress.
