Bed and mattress purchase

I am in my sixties and returning to the UK from the Falklands to a small house in Worcs. The bedroom is apparently also small and so I am after a small double bed and mattress, and a headboard. My budget is around £2000. I have read your bumph and am overwhelmed. I have no special requirements except a firmish mattress that doesn't get too hot, and an overall, all round good quality. I would need it to be delivered by Jan 10th 2018. Please can you advise me what you have? I notice Outlet prices too and am happy to consider any suggestions. Please tell me if my budget is unrealistic. Many thanks, Judy
