Works well. I've purchased two, one for me and one for my wife. I'm 5' 10" and she's 5' 4" and the footrest works well for both of us. I like being able to flex my feet.

It's just how it looks. It was easier for me to buy than build out of scrap wood. The adjustments work and stay in position. My dogs sit on my lap while I type sometimes and this keeps my legs level (OK, they're spoiled!). Also keeps my feet up and comfortable when the floor is cold. I often use bare feet and the tread is comfortable. Nothing fancy, just a foot rest that works...

Had forgotten about the NECESSITY of foot rests when at desk work. They were provided by my company when I was doing that sort of work, not home office as now. Years in between, forgot the item. Have lately been elevating my legs on pillows, because I might work 12-15 hrs. at a time. Got this, sat me up straight right now. Prior I would slouch eventually and start hanging off my ligaments, subsequent back pain. Is just right for me. Ordered one for my son for his office. It rocks if one wants that kind of movement at times when working. Looks substantial enough to me, I doubt I would break it. Glad for this item.

This foot rest though looks simple is a great invention. ' I am suffering from leg/back pain due to a herniated disc, and sitting is especially painful. But unfortunately i need to sit in front of the computer and sometimes at the meetings. ' I am not that short, even tall for a woman, but most of the time if i try to place my back firmly in the chair, my feet may not be placed firmly on the floor. This foot rest makes it posible. ' I can sit upright pressing my back to the back of the chair and also place my feet firmly on this rest. The good thing is you can easily change the height of the rest by changing the angle of it.
' Only I wish it had some kind of wheels, that would help to move it inside a room to different places(kind of wheels which are locked when you press on them. Who knows may be the manufacturer will improve the design.
One more thing; I ' had unintentionally ordered two of these foot rests. So when they first arrived ' I contacted the seller to return it. They immedately send me the label for free shipping. But i liked it so much after using it for a few days, i decided to take the extra one home, to use there.

I bought this because I am vertically challenged and wanted to make sure I was ergonomically positioned while working at my desk. I have had this for a while and it works great, I have had no problems or issues!
