The top of this is not a true concrete material. There are many "don'ts" for this kitchen cart top, which include do not put hot items, let liquids stand, no rubber based material, or use any cleaners on this top. The other issue I had was the color of this unit. The picture appears to be a greyish/brown there is no grey in this unit except the top and the hardware. The unit itself has red tones, no grey. However, it was very easy to put together and appears to be very sturdy. I could live with the issues of the top, but the color does not fit in my decor.
