Works well on the sofa
The cat scratches a lot on this mat after we hung it up on the sofa. We're going to order more so we can cover several popular spots. It's minimal in design, so it doesn't really interfere with the interior.
The only downside is that the tape didn't stick well to the sofa fabric. We solved this with some double-sided tape (from Clas/Biltema) around the edges. Now the mat stays in place, but it gets a minus for poor adhesion.
