Great sofa. Unlike a lot of "low-back" modern sofas, this one supports your back when you sit in it. It's very firm, but I prefer that. I purchased the grey sofa and it is MUCH LIGHTER than the picture. The picture makes it look like an asphalt color, but it is a much lighter grey. 

I'm also somewhat tall (6'-2") and the sitting height is perfect. But shorter people may find that their legs hang off the edge a bit.

Overall, it's a really nice sofa with clean lines and nice upholstery.
