double or king-size bed (Wavertree L17)

Hi Everybody, Could anyone please help me out with a double or king-size bed frame and mattress too please. I have just got a new place and I don't have much. I'd really appreciate it. As close to L17 L8 please, i don't drive but can arrange to have it picked up, or if it can be delivered I'd pay a fee. many thanks in advance.
