The ottoman is lovely and seems sturdy. 
I got it in the grey colour and I’d say it’s a true charcoal grey. Perhaps it looks slightly lighter in the product photos. The nailhead cover thingies are silver. It was easy to screw on the feet even for someone who’s hopeless at putting anything together. It’s also a really good size for a small space, and still has a nice amount of storage.

So far kitty isn’t attracted to the material as a scratching post, and she seems impressed with her new perch!
