double divan bed base (Shooters Hill SE18)

Hi has anyone got a decent double divan bed base they no longer need? I’ve bought a mattress but the base is a small 4ft and I need classic 4ft 6inches divan base. Only divan is suitable owing to a disabled user of the bed. I can collect se3/6/10/7/3 and surrounding areas bexley Bromley sidcup etc. thanks so much
