I use this desk from a seated position on a daily basis. All four wheels have locks. This is a problem because the two wheels closest to my feet keep locking up when I don't want them to. This is by far the biggest negative issue with the product. It must have two locked wheels and two unlocked wheels. The height of the table is achieved by telescopic tubes, but there is too much space between the tubes. This causes the table to tilt slightly towards the user. Pens or anything round tend to roll off. It's a bit troublesome. Overall, for the money, this product is a "worthy value" and nothing more.
