I don't need any more, I found a lot of advice myself.
Sofas with hard sides or armrests are no more fashionable, and I'll tell you that they went out of fashion a long time ago. Nowadays, more popular models with soft covering bring more comfort. Look at the modern sofa https://www.roomservice360.com/modern-living-room-furniture/sofas.html in this store. You'll understand what I'm saying. 90% of the sofas are all upholstered. I like the sofas of Nicoline Italia and have one of them in the living room. Many friends who come to see us admire it.
