ᐅ Ikea sofa from the year 2012?

Hello everyone,
In 2012, I purchased a sofa for which I now want to replace the seat cushions. To search online not only by the dimensions but also by the name, I need your help.

Can anyone tell me the product name? Does anyone have a tip on where or how to best find replacements? And what is the name of this fabric pattern?
I found several item numbers:
001.277.87
001.277.92
001.278.29

Thank you
