Question: What is the height from the bottom shelf to the keyboard tray?  I have a HUGE gaming computer that is about 18.5 inches tall.  Will it fit?
Document: For the price, this is a great product. All the pieces fit together, the instructions were clear, and it is surprisingly stable. I have a 23 inch monitor, and scanner on the glass top and a printer and computer tower on the bottom. The only cheap pieced on the desk are the casters. One in particular fails to rotate properly but it is able to be rolled around on the hardwood floors without much difficulty. If it wasn't for the casters, this is a 5 star product.
I bought this desk because i had a very small space to fit my desktop in and the style was perfect for me. The assembly was straight forward and easy...took about 20 minutes. Everything seemed sturdy when put together except for one part-the bottom shelf. Minus 1 star for having one of the thinnest bottom shelves I've seen.
This was very easy to assemble and fits very well in the spot I needed it for, it's not big and bulky but yet fits my computer very well, you can opt out the sliding draw for the keyboard and use as as a laptop desk as well.its very sturdy and Looks very nice, I love it.
A slightly thicker metal for the shelf would really make it excellent. Overall though I would recommend it.
it's a 5 star for a 24&#34; and under monitor, and just right for a 27&#34; which is my default monitor. I find the the 3/16&#34; thick top glass too thin for my 27&#34; dell monitor. Am planning to replace the glass to at least 5/16,&#34; 3/8&#34; is the ideal thickness.
It works perfectly for what I needed. It would be a great desk for student in dorm room or for a space saver. It is very sturdy.
I was needing something mobile to keep my Mac and printer on. I don't need anything permanent right now. This desk is just right.
I love this desk. It goes very well with my decor and i was able to get it by doing surveys and sharing my thoughts in several online communities.It was delivered on time and was in good shape. Thanks and keep up the good work for i will be buying more often.
This desk came in the best protective packaging I have seen. Ingenious and effective. The desk itself was a breeze to assemble, with parts on a well-organized blister-pack and clear instructions. Tools were included, except for a Phillips screwdriver (use a good one, as the screw holes are properly tight). The desk is just fine, if a bit small for me. This was deliberate on my part, as I wanted to down-size. A good buy.
Very nice desk and well designed. The only complaint is the glass desk top which seems to constantly need cleaned.
Answer: the measurement from the top of the bottom shelf to the bottom of the keyboard tray is 21 1/2 inches. the inside width of the bottom shelf is 29 inches with a depth of 16 inches from front to back.
