Review: Alternative to stand up desk - This is a good, inexpensive solution for a stand up desk. I was able to have my monitor and laptop set on this and still have room for external ten key and papers. Please be sure to place on a level and sturdy surface/table otherwise when typing, the entire desk shakes.
Review: It's like a bad ironing board - This thing is unbelievably frustrating! It's like a bad ironing board, it won't go up and it won't go down correctly! Half the time I have to take everything off the top and shake it really hard to get it to telescope up and I just pray every time I need it to telescope down! As I write this review I'm stuck in the middle and it won't go up or down!

## Features

- TALL REACH. SMALL DESK FOOTPRINT. - Your desk is fine; its height is not. Turn it into a sit-stand workstation with five fixed settings from 4.1 to 21.25 inches while the base occupies just 18 x 25.25 inches.
- RISES STRAIGHT UP - NOT TOWARD YOU - The patented accordion-style vertical lift travels up and down instead of swinging forward like many bulky desk risers, helping preserve desk depth and personal space.
- TWO KEYBOARD TRAY MOUNTING POSITIONS - Choose the upper fixed mount near the top panel or the lower adjustable-height mount for more control over keyboard placement during seated and standing work.
- SMOOTH, SIMPLE HEIGHT CHANGES - Squeeze the lever, guide the gas spring-assisted lift, and lock into one of five settings: 4.1, 10, 15.4, 18.75, or 21.25 inches. Quick tray attachment only; no drilling or permanent installation.
- BUILT FOR REAL WORKSTATIONS - The 20 x 28 inch top supports most laptops, single monitors, all-in-one computers, and compact dual-monitor setups within the 30 lb load limit. Steel frame, engineered wood surfaces, ambidextrous mouse pad, and 90-day warranty.

### ⭐⭐⭐ Alternative to stand up desk

This is a good, inexpensive solution for a stand up desk. I was able to have my monitor and laptop set on this and still have room for external ten key and papers. Please be sure to place on a level and sturdy surface/table otherwise when typing, the entire desk shakes.

### ⭐ It's like a bad ironing board
*by A***Z on June 7, 2016*

This thing is unbelievably frustrating! It's like a bad ironing board, it won't go up and it won't go down correctly! Half the time I have to take everything off the top and shake it really hard to get it to telescope up and I just pray every time I need it to telescope down! As I write this review I'm stuck in the middle and it won't go up or down!

### ⭐⭐⭐⭐ 1 size smaller would be nice
*by N***. on August 31, 2016*

Very sturdy and easy to move up and down but it is quite large and heavy. Would be nice if it were only about 3/4 this size. Would also be nice if it had more height positions as the top level is a bit too high but next level down too low for me. I leave it up most of the time as I do agree with other comments that you can't adjust it well with items on it and even without items it can tip slightly if not perfectly adjusted. So I move my laptop from one side of the table to the stand-up when I want to stand rather than sit. With the three tiers it is not comfortable sittingiving and using it.
