Coffee table looks much higher than the seat of the (really nice) couch. You should ideally look for a coffee table that is about the same height or slightly lower than the seat height.

I think carolins is right, the table looks a tad to tall. You could always compare the dimensions of the table height vs the height of the couch, just to be sure! (: Also it might just be just be just me, but i think with how you want to decorate a darker grey colored couch would look better! (:

Update: The height of couch with cushions is 25" and the table is 18.88" Is the table too high?

I think the coffee table might be under scale for the sofa - The sofa is heavy scaled (low profile, short foot, very horizontally oriented, where the coffee table is fairly light scaled. It may be the perfect height, but when paired with the sofa, look small. Perhaps think of another table with a heavier leg? Some examples below show similar style, but heavier scale.
