The Simplicity crib offers parents a way to save money. The crib's mattress can be raised and lowered for newborns and older babies. For toddlers, it can become a toddler bed and finally, it can be used as the head and foot boards for a full-size bed. Turning the crib into a toddler bed is simple. Teaching your toddler to stay in his new bed all night is the hard part.
Remove the front panel of the Simplicity crib. Use the Allen wrench provided with the crib (you should have stored the wrench and extra bolts in the pouch under the crib when you first assembled the crib). There are two 45mm bolts on each side of the front panel.
Check the mattress support. It needs to be in the lowest position available, which will allow the toddler to get in and out of bed easily. It is also the only position that will make the rails line up properly with the pre-drilled bolt holes. To lower the mattress, unscrew the four bolts from the four corners of the mattress support and slide the support down. The holes for the lowest setting are just about the bottom wood panels. Use your Allen wrench to reattach the mattress support with the same bolts you pulled out when the mattress was in the higher position.
Attach the toddler bed rails to the crib frame. Use two 38mm Allen bolts on each rail. There are pre-drilled holes in both the rail and the crib frame. Line up the holes and then loosely screw the bolts into place. The bottom of each rail has a metal L-shaped hook. This will slide under the mattress support. Use a 19mm Allen bolt to attach this piece to the mattress support. When everything is lined up and screwed in loosely, go back and tighten each bolt. Repeat on the other side.
Check the entire crib frame for loose bolts. Use the Allen wrench to tighten all the screws. Toddlers can be rough on their beds, so it is important to make sure the bed is safe. You should recheck for loose bolts often. Jumping and climbing on the bed can easily loosen the bolts and screws.
Store the front panel of the crib carefully. Wrap it in blankets to prevent scratching. The front piece can be used later to turn the toddler bed into a full-sized bed.
