Large corner settee (Quatropi)?

[Maryduice]

Hi, this is the first time I’ve posted. We bought, 4 years ago, a modular sofa (seats 7 comfortably) from Harvey’s with recliners at each end. The seats that are most used are so uncomfortable. The cushions are flat and the filling has pancaked. The faux leather bits have peeled.
We want to get another settee and have it last longer and stay comfortable. We have looked at the Quatropi cinema seating in an l shape.

Does anybody have any experience of this or recommendations?
Thank you so much.
