Thanks to previous reviewers, I knew exactly what I was getting - this is a dark charcoal grey (not black) and the 7 square rug is perfect for grounding my 36 square outdoor dining table and chairs.  Ive had it for 3 years - it still looks great - and is extremely durable.  I use a stiff straw broom to sweep away leaves and dried mustard came out with a simple hose down and a light brushing - no staining.  Yes, the rug comes rolled up tightly, but I simply rolled it out one the patio, hosed it down, put chairs at each corner and let it dry in the sun.  This was enough to flatten it out.  I store it in my shed over the winter.
The only downside is that I wish the edges were bound with a woven tape as opposed to the thin wrapped edge which is now starting to fray.  I bought another one for a separate outdoor lounge area this Summer.  Very pleased with value, quality and delivery!
