Very happy with this sofa! I do think it looks better with the big side cushions taken off! 
The measurements in the description are accurate! The deep seats are amazing! It is definitely not as firm as I expected. The other reviews made it sound very firm, but its more supportive than hard. I still sink slightly into the cushions when I sit on it and they have softened a little after having it for a month. 
The description said the material is corduroy, but it feels MUCH more plush  soft than corduroy in my opinion! Keep in mind, the foam density in the description has nothing to do with how soft or firm a sofa is, it has to do with the quality of the foam. Lower density foam wont last as long as higher density, so I am a tiny bit worried that these cushions may flatten a bit over time.
All in all, I am very happy with the sofa. Its VERY comfortable, I fall asleep almost every time I lay down on it! )
