The lumbar support mechanism and an adjustable bed therewith. The lumbar support mechanism includes a lumbar support member; first, second, third and fourth support legs; a linkage member; and first and second lumbar support brackets attached onto the adjustable bed. Upper ends of the first and second support legs are pivotally connected to the lumbar support member, and lower ends of the first and second support legs are pivotally connected to the linkage member, respectively. Upper ends of the third and fourth support legs are pivotally connected to the first and second support legs, respectively, and lower ends of the third and fourth support legs are pivotally connected to the first and second lumbar support brackets, respectively. As such, a distance between the lumbar support member and the linkage member is changeable between minimal and maximal distances when the linkage member moves between first and second positions.
