I use it every day. Very easy to raise and lower even with heavy monitor arms and two large monitors. The keyboard shelf needs to be tightened every so often but really not an issue.
I wanted something that would fit a couple of monitors and have room for my external keyboard and mouse. This is easy to put together use and has plenty of room.
I had been looking into different Adjustable desk risers and wasn't quite sure this would work for me.....but then my Staples desk riser arrived. It was quick to assemble and use. I love the ease of raising and lowering the desk. I am able to use it in both the raised and lowered position. I would highly recommend this product to anyone looking for an alternative to sitting at a desk 8+ hours a day!!
Tired of sitting? This is a solid option for your desk top. Lots of space for the second laptop and your notes. Good option if you want a table top model. It's big - base is 31 inches. Easy to move up and down.
