We bought the crib in our master bedroom from Eugene Club that measures: W 61 cm x L 107 cm. I think they call this a Medium. I can't imagine what a Small size crib looks like. My 2-y-o, now at 85 cm tall, can still sleep in it.
I have a smaller sized cot (smaller than US sized anyway!!) - I got it from Apita department store, but the brand is 0/3 baby. I believe that 0/3 baby has a store in Harbour Plaza TST and they have a decent range of the smaller sized cots. Many of the baby stores seem to have the big, US sized cots which were unsuitable for me - and they were 2-3 times the price of mine as well!!
