DS needs a new bed (he currently has a cabin bed). He is around 5'8 at age 13 and I am expecting him to be 6'1-6'2 based on his centile height from birth. I was planning to get him a long single bed (200cm long) from IKEA but have discovered they now only sell standard UK single beds (190cm). Is it worth the hassle of trying to buy him a European single bed from the limited choice on-line or just get a standard single. His dad had an extra bit of mattress added to his bed when he was a teenager as he found his standard single too short. How do your tall teenagers cope with a standard single bed? Am I over thinking this?
