The apparatus is a height adjustment assembly for a child's changing table with support tubes inserted into sockets at the top of a supporting structure such as a play yard. A height adjustment fixture external to the support tubes rests on top of the supporting structure and has a vertical series of recesses such as slots or holes and a ring through which the changing table's support tube slides. The changing table has an attached latching device that locks into the recesses to hold the table at several heights above the supporting structure. Alternate embodiments include a structure in which the height adjustment fixture contains the latching device and the recesses are in the changing table.
