I bought this sofa cover on Saturday in Belfast Ikea. It fits KARLABY / KILLEBERG three-seat sofa-bed. My sofa is BEDDINGE LÖVÅS three-seat and it fit well on it too. It is much better cover then the one from my original sofa.
There was two types of colour: white 140x200cm and dark lilac 120x200cm.
In the shop it say the original price £80 but on web it is £60.
UPDATE 6th December 2014
I just came back from Ikea Belfast, the offer is still there, till stocks last. !
There were 6 white and approx 5 dark lilac.
