Children grow up quickly. Fortunately, the Smartstuff convertible cribs can grow with them. This conversion kit easily converts your Smartstuff crib into a big kid’s bed. Using your existing crib headboard and footboard, these bed rails allow you to turn your crib into a full size bed (also known as a double bed). This allows for an easy transition for growing children without completely changing their atmosphere. You will also need a box spring (foundation or bunkie board will work also) and a mattress to convert your crib to a full bed.

    This conversion kit fit our SmartStuff crib perfectly. The finish matched really well and the bed feels super solid. We were able to keep using furniture we already loved instead of buying a whole new bed.

    Everything we needed was included and the instructions were easy to follow. Installation took about half an hour and the rails lined up perfectly. Very impressed with the quality.

    I emailed before ordering because I wasn’t sure which finish to choose. Customer service responded quickly and recommended the right one. The color match was excellent and the bed looks amazing.

    Our SmartStuff crib is over 10 years old, so I wasn’t sure we’d find the right conversion kit. This fit exactly as described and saved us from replacing the entire bedroom set. Couldn’t be happier.
