Convert your crib to a full sized bed with the Pali Universal Guard Rails. These rails feature sturdy wood construction and finishes that exceed lead and heavy metal content requirements required by CPSC (ASTM F963-07 and 16CFR1303). Converting from crib to full-size bed helps our environment by eliminating the need for new furniture using more new raw materials. We strongly recommend that the conversion rails be purchased at the same time as the crib. Please note that, when converting the crib into a full-size bed you need to use under the mattress either a box spring or a bunky board.
