Hi, a friend is giving away a bed that is perfect for my son for when he is ready to move from cot to bed. The problem is that I live 150 miles from my friend and I.don't know how I could get it from hers to mine. It is a single divan on caster wheels, with single mattress and head board. Do couriers such as dhl collect and deliver items this big or can anyone recommend a company I could use. Many thanks.
