Metal bed fram from the range

[Miss2mrs]

Hi, I'm wondering whether anyone has an Ava metal bed frame from the Range? MOL has just bought one and now doesn't know whether it will fit up her stairs. I thought that bed frames with wooden slats came in separate pieces but the store has told her the base comes as one piece. I've looked on,line for the instructions and spoken with customer services who weren't able to help other than to say if cones in three parcels! I just wondered whether any of you lovely ladies had one and knew? Thanks in advance.
