dear Master Lee, We live in Hong Kong and as you know, in HK, space is limited. Therefore the rooms are very small, no space for single bed + 2-door cupboard + study table for children. I'm considering to put the study table under a bunk bed in one room for one child. Another consideration is to use a double decker bed for another room for another child (the child sleeps on top and maid sleeps below). Are these arrangements ok? Thanks in advance for your kind advise. Regards Loh Soh Hoon
