Search for Ikea name for checkered 2-seater sofa

Hello! We bought a blue and white checkered 2-seater sofa in Sept. 2001, whose number is 683.931.00. Does anyone know the name or if an Ektorp cover fits on it (except for the decorative cushions)? If it helps, I will try to upload a photo -> see my avatar :) Greetings Lena

Could it be Vingaker?

HAGALUND?

The dimensions unfortunately do not fit. I will try my luck directly at Ikea tomorrow. The Multi Fit cover from Bemz would fit, but is unfortunately a bit expensive.

Yes, the Bemz covers are really quite expensive. VINGÅKER was a sofa bed.

Thank you! It is not a sofa bed, so the idea is out.
