Love this unit. It just makes my room look finished. However from the picture on the website, I did actually think that the grey marble was hi gloss. It doesn’t bother me as it looks fab. 
Major factor to take into consideration though, it has to be the most difficult flat pack that we’ve ever had to make. The instructions come on the outside of the box rather than on a pamphlet and the instructions are as clear as mud!! It took my other half (engineer) and my next door neighbour (electrical designer) over 6 hours to build. Once it’s built it’s a beauty though. 
As you can see from my picture, it looks good and it does what it says on the description. Our tv is 75’ and there is still space at either end.
Wayfair customer services were also very good. 
Thanks
