Question: How does the top caddy shelf attach?  and can desk be used without it or does it leave holes in desk top?
Document: The drawers didn't fit in the predrilled holes without rubbing against one another. Wish I had gone to a furniture store and bought a real wood desk for a couple of hundred buck more.I do like the design but would have preferred a more durable product. It is a good product for folks with lots of time and limited income.
This is a nice desk for the money. I would have liked to have had 3 drawers on the right side like it looks like there are, instead of 2. The drawers can only hold 50 lbs, which isn't much, so the drawers are crooked and don't close right. I need to do some adjusting on the drawers to see if I can get them to close without rubbing. The shelf is okay, but doesn't give you much more organizing space.
Bought one of these at Orchard Supply. Was happy with it at first but then tried to move itand it started coming apart. Tried to brace it but was not able to. Going in the trash. It isOK if you leave it in one place. It is very heavy for a small desk.. Also where I used the mousestarted to wear through and expose the bare particle board after a very short time.
This desk is a perfect size for my needs. The only reason I rate it a 3 is because there is a break in the top at the back, a half circle about an inch wide. Fortunately, it is under the shelf so not easily seen, but if it were in the  front, it would have been returned immediately. They should be thoroughly inspected before they are packed. This is very obvious.
Hoping to revise this after a response from Sauder, because I REALLY don't want to attempt to repackage this thing and ship it back. This thing weighs 113 lbs. There's some kind of major packaging problem, because my desk is damaged in the same places mentioned by many of the other dissatisfied customers- along the front edge and on the top shelf of the return.
This desk looks amazing and works wonderfully. It's so nice to have a little shelf to create extra desk space. To me, the dimensions are perfect. It's nice and wide and deep, but not huge.My only disappointment was that I thought that it had three side drawers, but it's a fake drawer...kind of. On the righthand side, there is a bottom drawer for file folders, and there is a single deep top drawer which has two handles, but is only one drawer.
First the bad news:1. Expect some damage to some of the pieces because the desk is poorly packed. In my case, the desk top was damaged and one of the drawer fronts actually had the holes drilled for the handle in the wrong place!2. Expect to spend at least 2 hours putting this desk together(this is how long it took me but if you're not really handy I can see it taking easily twice as long - there are lots of parts).3.
I gave this to my son for his birthday (16).He didn't have too much problem putting it together (some impatient frustration)It looks nice and fits where we wanted it to.It did come with a small chunk mark on the top shelf which we just put markeron so you can't see it.Worth the money.
We bought one does for our business and, while it did take a while to put it together, it was totally worth it. For the money it is the best quality desk I have seen in a long time. After we used the desk for a little and fell in love with the color we ordered two more. For the price you cant beat it.
I used carpenter glue for added reinforcement. It should help stabilize then fasteners.Solid desk and they look great in the study room. Not real wood, mostly particle board with veneer. But it still should hold up for several years.Very pleased with the desk.
Answer: There would be 2 holes about the size of a pencil if you chose not to use.
