I want to build a sewing table for a 30-40lb sewing machine. Is the base sold without the table?
A shopper
on May 17, 2019
BEST ANSWER: Yes. I placed 100 table to on this plus computer, monitors, etc, without issues. Frame can lift 265 lbs and there is also a 2 leg model. You will probably have to center your sewing machine in the middle of the table to for better stability. You don't have to get the monoprice counter top/desktop. You can buy a different counter top with

the base seems stable at lowest levels. The higher I go the more shaky it gets. i suggest getting the table top with the base

Am i understanding this correctly- this is a frame only and no top?
Glenn W
on Nov 7, 2019
BEST ANSWER: Yes, that's correct. You can make your own, or purchase one to fit the size desk you want. Since it's expandable, you can get a very long surface if you want. I couldn't find what I was looking for in my area so I had to drive 150 miles to get a top for the frame. There aren't really good instructions on how to measure the frame to fit your desktop, but just use your best judgement and it will work out. Most of the assembly can be done with one person, but I recommend two people for the desktop to ensure it's square.

Correct--as it says below, you'll need to buy the surfaces separately. Or, if you already have a desk surface, you can use that. (In my case, I replaced the legs on an already existing corner desk with this frame.)

That is correct, this is only the frame. You can purchase table tops separately from Monoprice or you can purchase table tops many other places to fully customize the look of your desk.

Yes, Only the frame. They sell tops for them that are fairly inexpensive but the shipping is outrageous. They quoted me just under 300 in shipping for just the tops.

Is there a technical drawing available of the Corner Desk Frame? I need to know the position of the middle table leg in order to design a table top cut from a 4'x8' sheet of plywood.
New User U
on Apr 14, 2019
BEST ANSWER: Hi, we don't have a technical drawing but we have the drawing on the product page with the main measurements labelled. If you need specific angles or measurements, we might be able to get screenshots from our 3D file. The dimensions of this desk are adjustable since both sides of the desk frame can be stretched out. The main dimensions to consider would be the foot dimensions (27.6") and the widths that you will decide to use for the frames. Thanks for checking.

Sure, I can check out the drawing. And yes, the intersection of the horizontal members do have to be at 90 degrees because of the way the frames connect. You can see more details of this in the manual, which has a link towards the bottom of the product page. you can check step# 3 and #4 to see the frame parts and how they connect.

- Irv S Staff on Apr 24, 2019
OK, I know what happened. I'm confusing this device with another one from a different site which does not need a 90 degree intersection. And 90 degrees means my single sheet of plywood for the desktop won't work. Thanks.

I have a desktop that is 36 inches wide and 66 inches long, my return side is the longer more slender side at 22.5 wide and 84 long. Will these dimensions work with these legs?
New User U
on Mar 4, 2019
BEST ANSWER: Hi, it could work if the shorter side of the desktop will be right next to the longer side of the return, so the outer edges of the L-shaped desk will effectively be 88.5 (66+22.5) inches x 84 inches. Just note that you will have some overhangs for the main desk and for the long side of the return, so just make sure that the desktop is durable enough. It would also be best to place the heavier loads away from the edges to make sure the frame is able to support them. Thanks.

What is the warranty on the motor on these legs? On the frame itself? Is it adjustable lengths to fit multiple table tops?
New User U
on May 28, 2019
BEST ANSWER: Hi, the product has a standard 1 year Monoprice warranty. The materials and construction are quite robust on these desks and would easily outlast the warranty. The frame lengths are adjustable and could fit a range of table top sizes. You can refer to the drawing with the dimensions labeled on the product page for more information. Thanks for checking.

I have limited space for the return side. Going by the diagram in the user / assembly manual, if I use the 4' table top for the return and the 6' table top for the main portion, it looks like the return is effectively 4' + 29.5", which won't fit in the space I have available. Could I use the 4' table top as the return, and then 6' table top to wind up with 6' + 23.5" for the main portion of the desk?
A shopper
on Jun 6, 2019
BEST ANSWER: Hi, the 4' top by itself won't be long enough to cover the desk frame on the return side and probably won't mount properly if it does not reach the top support. If the desk frame dimensions fit your space, you could consider getting a custom desktop that's short enough to fit but long enough to cover the frame and mount properly.
An alternative might be to have two sit-stand desks, like 31290 (single motor dual leg desk) and 36079 (single leg desk). They would be separate desks but you would have more flexibility with positioning them.

Are there any recommended monoprice accessories for this motorized corner desk? For example, I would like to add an integrated keyboard mount on the under side of the desk itself, probably in the corner on a 45 degree angle for instance. Any other accessories that anyone has added that have contributed to ease of use?

The description says to combine two tops at right angles to make the L-Shape. However, as far as cutting a top for this I am unclear if the longer piece goes on the side with 2 perpendicular supports or on the other side with 1 perpendicular and 1 parallel support (side with the controller shown in picture)? My intent is 72"x30" with 30x30" on left side.... so for top dimensions would I use 42x30" (front) with a 60x30" (left) or 72x30" (front) with a 30x30" (left)

Perfect for my home office!
Just what I needed for my home office/command center! Be prepared to have to return a top if you get it from Amazon- their shippers dropped the 4th section on a corner and smashed it. Only option was to return it, and pay $10 more for a replacement, that took 10 days to arrive. The 6’ section from Monoprice arrived without issue, though.
One quick note: “pre-drilled” applies to single section desks. On the L-shaped, one side won’t match up. The provided screws are self-tapping, but I pre-drilled “just in case.”

sweet standing desk
great desk. bought it on sale when it was down to $400 for only the frame. weigh a ton in the box it came in. after assembly it found it to be sturdy. built my table top out of 2 pieces of MDF painted glossy extra white color to match the legs. able to have a 74 inch by 32in front piece and a 36inch by 32inch side piece. love the 4 height settings to adjust 1 for sitting in a normal office chair, 1 for sitting in a higher chair, and 1 for standing.

Great Corner Desk!
This desk was exactly what I needed at a great price. It took a little while to put it together but all of the parts are heavy duty and feel like they will last a very long time. The motors also work well and are fairly quiet. They have no trouble lifting my three monitors along with the other stuff on my desk. The only issue I ran into was the top that goes with this base only had some of the holes I needed pre-drilled. This wasn't really an issue but it wasn't clear that this was the case before buying them.
