I don't know if my title makes sense but I'm soon to divorce and I've had the DC in bed with me since they were little (NOT the reason we're divorcing!). We're in a SK bed atm but as DC are getting bigger, even a SK doesn't feel big enough so it's time for some changes! Their dad will be moving out in the spring so I want to move into the slightly smaller room and get the DC used to sleeping by themselves on a bunkbed. I'll have to move the SK nextdoor but the only way it'll fit is if I have it on its side so that the doors of the fitted wardrobes can open comfortably. So the bed will be 200cm wide and 180cm in length placed on its side. My issue is that even though I'm 158cm tall, I've been in a SK so long, I think I'm going to find the shorter bed really uncomfortable! Also, can I use a mattress on its side or are they designed to be used lengthways only?
