I just bought a Malm twin bed, and when I looked up the bed online I saw a lot of people complaining about having to buy a Skorva midbeam. This was all in reference to full, queen, or king sized Malm beds, however. Do I need the midbeam for a twin sized bed? The bed came with something that looks like a metal midbeam, but I'm not sure if it is one because it sounds like the midbeam is not included in the box with the bed.
