Question: What is the height from the floor to the keyboard tray? (Please specify if you're measuring with or without wheels) Thanks!
Document: Came with a damaged roller on the desk tray. Company is very reasonable to deal with and sent replacement parts out. Rolls very nice. Looks great. Hinges are stiff on keyboard tray so hard to close. Good solid construction and ease of assembly.
Overall I do like this desk. I am happy with the purchase.Good-*Wheels are nice and solid (not cheap plastic wheels), rolls really nice on wood floors*Made of pieces of wood, not pressed particle boards*Well packaged*Good height for work spaceBad-*Center shelf is very thin (needs to be made better), mine split when I put it in place.
(7) The wood finish was bummed in several places. I used touch-up markers but... well, you know how tacky that is. (8) The final insult was the overall height of the unit. The top surface sits 32" above the floor. I suspect that the unit was originally designed for smaller casters, and when the caster size was increased, no compensation was made for the height.So why didn't I return it? I'm retired and must walk with a walker.
Very nice product for the price. All wood materials that were relatively easy to assemble. Designed for a computer tower with adequate room for a printer and paper storage. It has a tray for pens, pencils, paper clips, etc. inside the keyboard tray. The top surface holds my 23 inch all-in-one comfortably.
- the height of the top and keyboard are a bit above the norm, but shouldn't  be an issue for average height users - i'm  6ft 3in tall, and for me, it's just about perfect - all in all, a good value.
The GoodStylish, Sturdy, Casters make moving it around and hooking up the computer easy. The directions were clear but pay attention where the holes should be for the shelf. Packaging was good, couple of dings on the wood but they seemed to be in places that can't be seen.The BadThe keyboard tray needs help. The drawer rails are horribly weak and there is to much play which makes the drawer difficult to open and close. Also most keyboards won't fit because the tray surface isn't deep enough.
This is a good product for the price. The casters are high quality and the wood is natural and sturdy. The desk ends up a little high, it is the keyboard shelf that is actually at standard desk height. That keyboard shelf and the "printer shelf" are both flimsy, though.
This is a nice solid and attractive cart. My MacPro fits on the pull-out shelf and I put my printer on top. The pull-out shelf is just the right height for the keyboard. The little space on the side bottom is the perfect size for my purse, and I keep printer paper on the other side. Everything fits nicely, and best of all, my Roomba vacuum can roll underneath it! No dust bunnies!
This cart is attractive and easily assembled. I like that it is all hard wood. It rolls easily on the wheels. If you have an ergonomic keyboard with a curve to it it will not fit in the drawer.
Wood is solid and attractive, but it arrived chipped in places. Size is a problem - it is 32 1/4 inches high, not 31.1. Because I'm just over 5', my feet barely touch the floor when I adjust my chair to use the keyboard comfortably. Even then, it's too high to use for any length of time. Fortunately, it's for my home office, not for full-time use.
Answer: From the floor (with wheels) to the very top of keyboard tray (when open/down) is 70.5 centimeters.
