You can quickly set up the BABYBJÖRN Travel Crib Light with one simple trick. Take the travel crib out of the storage bag. Hold on to the short sides of the frame so that the legs point down toward the floor and open it up in one swift movement. With enough force, the legs fold out by themselves. Make sure that all four are locked in the right position before putting the mattress in. Fasten the mattress to the bottom by pulling the red loops through the holes in each corner and fasten them to the red hooks. This ensures the mattress will not slip within the frame.
