Actually, there were several metal pieces that came with the bed frame that were supposed to be fixed under it, but I had no idea where to put them and the instructions didn't help (the holes were missing and I didn't fancy having the bed frame collapse on my head), so they're sitting in a cupboard. :P

Interesting style there...

In Singapore we only use a bedsheet and a blanket (and some days, not even a blanket). :P
