It's as big as expected and is perfect form our space.  It's not the sink-in comfyness you would get from a down filled type of cushion but I would not call this firm -- the sink-in is just right, a nap the first day confirmed that!  The seat is more narrow in depth than I thought it would be but it does seem to be just right.    I do wish the back cushions had more firmness/fill as you can feel the back rest and it is not comfortable to lean back on ... quite the disappointment actually - I don't feel I will be lounging in this as much as I was hoping I would.  Extra pillows are moderately helpful. I don't recommend a couch with this bolster type of back rest.
