Question: Does the whole top lift up or only a portion?
Document: What an awesome table. Love, love, love it. The drawers are spacious. The storage under the table top is generous. Love the side drawers which are roomy and convenient to reach. The lift top has three convenient stops at different heights. The color is just as pictured. A beautiful piece of craftsmanship.I was concerned about online furniture shopping, but the whole experience was easy and flawless. Delivery was prompt and damage free. I would highly recommend this dealer and this table.
The lift top is a little high, (mid chest when sitting on my sofa, and I'm 5'9&#34;) so if you have a very low sofa this probably won't work for you, but for us, it works out well.
The lift up top is a cool feature, but depending on how low your couch sits, it can be a bit of a reach. I doubt we'll use that very often...The color is very nice, just like the photos.
Our table just arrive without any difficulties. It was well packed and the only assembly required was to put on the casters. This table is well made, has lot's of storage and a sturdy lift top. We both are very pleased with this purchase.
We ordered the matching end table at the same time. We received them in a timely manner and they were both packaged extremely well. My wife does puzzles and she uses the lift top to keep the puzzles in a comfortable position. She also uses the many drawers to store her boxed puzzles. We are very happy with our purchase.
Although we didn't find three distinct levels of the lift-top on this lovely table, the top does stay at whatever level you'd like. The table is very substantial and well-made, delivery was wonderful, a quality piece of furniture at an affordable price. My husband and I are very satisfied with this purchase.
I purchased this table for the style and the lift top feature and because it came with the Ashley Furniture Tag I thought it would be a well made piece of furniture. I ordered this table in November 2013 - and purchased it from Home and Living.com thru Amazon.com. The table was backordered but arrived on December 10th, 2013  faster than originally stated by the Seller.
Very nice construction, top seems sturdy enough. Love to use on the nights we dont sit at the table for dinner or when I m doing school work on my laptop. Comes with caster to install if you choose. Be cautious if you have hardwood floors it will take you for a ride.
I purchased this coffee table today at Living Spaces. It is very nice, dark brown, with a sturdy mechanism to hold the table top at different elevations. There are drawers on 3 sides (total of 4 drawers) none on the side towards the sofa. It was $360 and a very good buy in my opinion. Would recommend to anyone looking for this type of table.
I contacted Amazon (so much for their A-Z Guarantee Policy) and Home and Living to see what options I had to either get a replacement Top or exchange the table for a new one. I am disappointed that Home and Living.com is not standing behind their merchandise. Since they only offer a 30 day return policy - I am now stuck with this damage table.
Answer: The whole tabletop is hinged onto the base, and it lifts up and forward a bit.  That forward part is what keeps it from falling right back down, and the piece is so heavy that it does not tip over.  Only the tabletop moves, not any part of the base or the drawers.  The piece is quite heavy, but it moves easily because of the (mostly) hidden wheels at the base.  I absolutely love my table because it has quite a lot of storage, it serves as a coffee table, and then it serves as a higher dinner table when I eat in the living room.  It is also convenient to have the table at a higher height for jigsaw puzzles.
