This is a very well constructed raised garden. Thoughtfully designed. 
The gray stain is very light , but very nice. 
I was a little confused on how exactly to attach  the liner , it hangs over the edge by several inches - so I tucked it into the metal cover frame. I haven’t attached the cover yet as I’ve just planted my herbs , but it appears to very nice.  The frame is very sturdy and doesn’t wobble. Adds stability.
I will say even though I measured , the garden is larger than I thought it would be. 
I like it a lot , but wish I had purchased the version with flat back than is a little smaller. 
I purchased the small regular one - but to me , it’s more of a medium size. 
I purchased 3 bags of soil - 30 lbs each and it was the perfect amount.
