Posted under sofa futon

At the moment i have a realy large sofa that when we moved in i had to have the frontroom window removed to fit it in.
My kids with a little help from us have spoiled it and i want a new one.
Trouble is i have a narrow front door.where can i buy a sofa to fit through it.All the ones ive seen are massive,can you buy self assemble that is not a futon. cheers for any help lol

I had 2 new sofas in February this year and have a small front door and a tiny turning space into the living room but they just took the arms off them and assembled them in the living room. Got them off DFS
