A futon bunk bed is a great option for a kid's bedroom if space is tight, you have children sharing a room or you want to create a sleepover-friendly zone. A metal futon bunk bed consists of a metal frame and features a single top bunk, a double futon base and a ladder. The bottom bunk quickly converts from a sofa to a bed, as required. The assembly process varies by model, but most metal futon bunk beds are relatively easy to put together.

Components and Tools

Before assembling your metal futon bunk bed, check that you have all the necessary components and tools. The basic parts include a ladder, legs, headboards, footboards, cross bars, bed slats, safety barriers and futon frames. Various sizes of bolts, nuts and washers will be included. Allen keys and spanners may be included, and you will also need a screwdriver and rubber mallet. You should not use a power drill to insert screws, as this could damage the unit.

Headboards and Legs

Attach the headboards to the legs. With all pieces laying flat on the ground, attach the headboard to one of the legs using the correct size of bolts, ensuring the washer is curved inwards toward the hole on the headboard. Do the same with the lower headboard. Attach another leg using the correct size of bolts. Screw a filler bar to the headboard, if there is one. Some models have filler bars for added strength. To a third leg, attach another headboard and the lower footboard, then attach the fourth leg. Screw a filler bar to this headboard, if there is one.

Top and Bottom Cross Bars

Two people must attach the top and bottom cross bars, which connect one end of the unit to the other. Use the screws and washers to attach two top cross bars and two bottom cross bars to the legs on one end piece, then the other. Carefully stand the unit up. Lay the bed slats on the ground. If the slats have hooks, make sure they're pointing downward. Carefully lift the bed slats onto the top bunk. Use a rubber mallet to gently secure each slat lock into the cross bars.

Safety Barriers

Use the bolts and washers to attach the safety barriers to the cross bar of the top bunk. In some models, the ladder can go on the far left or far right side of the unit, while other models have a set ladder position. Decide on your ladder position, as this will determine where the front safety barrier goes. However, you don't attach your ladder at this point. Use the bolts and washers on the underside of the cross bar to secure both safety barriers. The top bunk is now assembled.

Futon Assembly

Attach the spring hinge on one of the footboards. Lay one futon frame down with one end over the spring hinge. Attach the frame with bolts, nuts and washers. Repeat the step on the other footboard, attaching the other end of the futon frame to the second spring hinge. Attach the second futon frame to both spring hinges. Secure your ladder in place. To make the futon frame into a sofa, lift the edge of the nearside futon frame, push it inward and set it down to lock it in position.

Safety Tips

Always use the recommended size of mattress for your futon bunk bed to prevent falls and injuries. The surface of the mattress should be at least five inches below the upper edge of safety barriers. Children under 6 years old should always sleep on the bottom bunk, and only one child should sleep on the top bunk at a time. Always use the ladder for entering and leaving the top bunk.
