Frequently, toddler beds come with built-in bed rails, however, you can purchase a bed rail to install on a full-size bed to help save the money and trouble of purchasing a bed that serves as an interim solution. A bed rail is designed to fold into the bed frame, requiring no modification to the frame itself. Make sure you choose the right wood (non-toxic) and that the finish is not toxic. Most models of toddler bed rails are made to fit between a mattress and box spring, using some variation of an L-shape. The actual height of the bed rail varies, and can be affected by the depth of your mattress. This is an important item to consider when looking at the size of a rail. If you are left with only a few inches of protection, a restless child can roll right over the top at night.
To install a toddler bed rail, clear off any sheets and covers that are on the bed to increase your visibility of the task and reduce any potential obstructions.Insert the bottom portion of the bed rail between the mattress and the bed frame, pushing down on it until it is secure. Repeat step 2 to install the bed rail on the opposite side of the bed. Put the sheets and covers back on the bed, tucking them snugly in between the mattress and bedspring. Fold the bed rails up and apply light force to each rail to ensure that they do not move.
