Step 3:
A. Flip the mattress support so the "This Side Up" label is facing up. If the label is missing,
the correct orientation is with the springs at the top of the frame.
B. With a helper to hold it at the right height, align the screws on the Mattress Support (D)
with the holes on the crib sides and tighten with the allen wrench. There are three possible
height positions. The support should start at the high position for newborns, then be moved
lower as the child grows and becomes more mobile. Once the child is able to pull up to a
standing position, the support must be set to its lowest position.
