Color and measurements are just as advertised.  The "Dark Grey" is more of a medium grey.  The photo is the same shade as the product, so don't assume it will be any darker.  We are using it as an ottoman for an heirloom chair in our bedroom.  The small size, and 14 inch height, make it a good match for this older, smaller, and lower chair.  It was just what we needed.  Most ottomans we looked at were just too tall.  No doubt that it is firm enough to sit on, but we will be using it more as a foot rest. This product, in a brighter color, would also work well for seating in a children's room or play room.  We are pleased with our purchase.
