Question: How much assembly is required?
Document: I'm a believer! This desk is a great fit for my small home office space. It's sleek, solid and sophisticated. I love the desk and folding bookshelf so much, I'm buying another shelf. Screw in four posts and a knob... unfold a bookshelf straight from the box... and you have an office in minutes. If you hate &quot;assembly required&quot; like I do... you will love this desk and the rest of the Dolce collection.
The desk was just what we expected. Packaged very well, just the right size and color. Assembly was super easy too.
This desk is surprisingly sturdy and requires minimal assembly, just putting the knob on the drawer and attaching the legs. My 11 year old is using it for a computer desk and she's very happy with it.
I was very impressed with this piece of furniture. It is solid wood, well constructed and not cheesy in any way. It looks like I paid a lot more for it than I did! Assembly took about 5 minutes.
I just got this desk an hour ago. It looks the same as picture. Easy to assembly. It take about 10 mins at most I guess. I strongly recommend to anybody who want a good one !
I purchased this desk and I expected the assembly to be tedious. To my suprise I just had to attach the legs and tighthen the drawer, thats it! the mahogany finish is fabulous and it compliments my home decor as well. I was suprised at the sturdiness and durablility of this product. This item is constructed well and resembles those at higher-end retailers without the stiff price tag!
I'm very happy with this item. It's relatively light weight (one person can lift)  which makes assembly easier. It came with a how to assemble diagram and all the hardware was included, plus the allen wrench. The piece looks great. The desk drawer slides in and out easily, fits the opening without unattractive gaps, and has a lot more capacity than I expected. I researched the produce before buying and there were numerous comments about the item arriving damaged.
I was looking for a sleek writing desk for my laptop. I am very pleased with this purchase. The assembly was a snap as it came pre-assembled, all I needed to do is screw in the legs. Piece o' pie! I was good to go in 20 minutes! The color is even nicer than pictured. The dark walnut has a slight reddish/mahogany hue to it. It coordinates very well with the rest of my furniture. The price was right and the desk arrived within 2 days!
I recommend using a flat panel moniter with this desk because it really accent the desk nicely and does not take up much space. I highly recommend this item.
For the price, I am very disappointed. I think I paid $20 for the original one at Target on clearance. I paid 5x as much for this one, and it's not as nice.
Answer: It just the legs and the drawer knob.  All hardware is included but you will need a phillips screwdriver if I recall.  Takes about 15 -20 minutes.  Looks great.
