PURPOSE: A beam matrix is provided to prevent the grounding phenomenon by the height of the beam matrix with better dispersion of body pressure, thereby effectively preventing and treating a bedsore. CONSTITUTION: A beam matrix comprises: an air generation part(12) generating air pressure; a distribution part(14) for controlling the air pressure by operational signal; a supplying part(20) connected with the distribution part; a matrix part(30), which comprises a first cell member and a second cell member, swelled by air pressure supplied through the supplying part. The first cell member and the second cell member are connected each other, and arranged to be facing each other.
