I absolutely loooove these couches! I bought blue and gray! Only took 5 minutes to put together. They are nice and firm (which I like), but oh so soft! Yes they're a little low to the ground but it was only 2 inches difference from my previous couch. They are a shorter couch, but fits my space perfectly! 
I was nervous about buying my first couch online, but thoroughly read all the positive reviews and I'm so glad I took a chance. I did a happy dance when I saw the beautiful blue color in the box! Can't beat the price and hoping for decent longevity!
