Looking for a name for a replacement cover for my Ikea sofa

Hello dear Ikea fans I have an IKEA sofa and would now like to buy a replacement cover, unfortunately I no longer know the name of the sofa :(. On the cover there is the following tag: ID-No. 18988. Maybe you can help me. Thanks in advance.

Hello Mooncat,

unfortunately I can't do anything with the number either, but just ask at CoverCouch.
The site offers a large selection of replacement covers for many IKEA models.

The website is covercouch.com/de and they might know which model you have.
At least that was the case with my model and the sofa covers for it...

Regards
