.BUT for some daft reason Delivery to Northern Ireland costs a ridiculous £160?? .

Ask if they will allow a courier to collect.
I got a Scottish courier to collect a motorcycle exhaust (nothing to do with chairs, but it was a BIG parcel) from somewhere near London to Belfast for £25!
If you want the name of the company (I'm not on commission!) PM me as I think giving their name here would be advertising?
