Double Bed & Mattress (CT19)

Hi, I’m moving into a new flat and have nothing.
I particularly need a bed and mattress, ideally double size.
I would prefer the wooden slated type as easier to transport and get up the two small flights of stairs for a female doing everything on her own.
I will be hiring a van for the afternoon of 3rd September, or as close to then as possible, so if it was possible to pick up then, that would be ideal.
Thank you.
