Ok, so it's just under £2k but it came, fit through the doors but got wedged on the stairs which I hadn't thought of. I felt so bad, there was no way they thought they could do it and I think they might have been concerned about damage too so I said we'd try.
We've tried and it will not fit. Physically can't. What are the options? Take out banisters? Through the window?
I accepted the delivery so I doubt they'd take it back for a refund as they said they won't repair any damage if it were to get damaged so we've been careful not to push it too much.
