I love the design and functionality, but with the way the hinge is designed it locks into place, and is very very loud as it adjusts through the heights. I know that seems like an arbitrary annoyance, but it is loud enough that it freaks my dog out and she refuses to come any where near the couch now when I sit down. Poor thing just runs and hides! 
But for storage and functionality overall it is a useful piece, and doesn't look like a bulky overly traditional item like many transitional coffee table like this.
