I love this desk so far - the assembly wasn’t too difficult, the desk feels sturdy, and the workspace is larger than I expected (in a good way). 

The desk comes with two forms of leg rests/support. There are four flat disk type supports or four lockable wheels. I can’t testify to the sturdiness of the wheels, but the flat supports are great. If I try out the wheels in the future, I will try and update my review. 

The desk has four programmable heights that you can set at your preferences or you can just use the up/down arrows. 

For the price, this is an excellent quality sit/stand desk and it suits my needs perfectly. I was worried about the sturdiness (which is fine), the size (which is great), and the overall quality of the materials but I wasn’t disappointed with any of it. : )

If you are on the fence about buying this desk, I would advise you to get it.
