A twin over full futon bunk bed must contain support for futon mattresses, which lack the internal support of a traditional mattress. You can also use them for just a regular bed mattress, eliminating the need for box springs. There many bunk beds together with only rails, futon bunk beds have a grille or set of bars that provide extra support. Metal arches come from many different manufacturers, but most work on the same basic framework.
Clear the area of the room where you want futon bunk beds. You should have room for the full footprint of the bed, plus free space to walk around. Identify end caps in bunk bed frame, using the manual if necessary. Place them in place, approximately where they will be when the frame is built and installed. Check the installation hardware for the bottom mattress frame. This usually consists of several hexagon nuts with corresponding washers and nuts. Collect enough for installation and place them in a pocket.
Align the holes in the bottom mattress frame with the mounting holes in the end panels. Slide the hex bolts into position along the washers. Tighten the nuts in place. Repeat steps 3 and 4 to install the mattress pad. This will be much easier with the bolts for the bottom bunk bed a little looser – it gives you some turning space. Use the Allen key and pliers to tighten the nuts for all connections. Test the bunk bed by shaking it with a weak hand. If it swings lightly, double-check for loose nuts. Side bunk bed in place, and then add mattresses.
