A friend of mine at work is selling his single bed and matress (he has moved home so bought A double bed for his kid).
He advises me they are in immaculate condition with the matress being of top quality and used only for 5 months by a 5 year old. (with no maps of Africa on the mattress)
He is looking in the region of $250, will throw in the bedside cabinet for an additional $50.
Let me know if you are interested.
