Ordered this to be used with my kalani 4-in-1 crib (which it is supposed to be compatible with), however the rail that I received in the mail was too small and made for the “mini crib” not full size crib. Beware that some of the color options on this listing are meant for the mini crib and not the full size cribs. You can tell which ones are larger by the picture if you count how many rails are on the toddler rail. The smaller one has only 6 and the larger one has 8.
