I absolutely LOVE this coffee table!  I didn't actually need a new one, but I saw this while looking for a friend.  I like to do puzzles, color, or just be on my lap top while on the couch and I would always have to hunch over to do any of these things.  The fact that this has a top that lifts up and comes closer to you is the main reason I bought it, plus I love the way it looks!  After putting it together (with a second person) and trying out the lift top, I immediately knew it was worth the money!  I've had it for only a week, but it seems as though it is of high quality materials and should last a VERY long time.
In case this information is helpful, the top is about 6.5" higher and comes about 1' closer when lifted (I am not sure why they put the shelf height at only 20.75").
