The Ergotron WorkFit-A lets you move from sitting to standing at work. This can be a distinct relief to the body, which can get saddled with back pain, bad posture and slow metabolism due to long, continous hours of sitting.

One of the highlights of this WorkFit-A is its innovative design, which does not require the iMac stand to be removed before mounting as long as the weight of the iMac monitor satisfies the weight capacity of this workstation (please see the compatibility guide given below). The stand of the iMac slips easily into the assembly of this WorkFit-A so no VESA adapter kit or built-in VESA configuration on the monitor is required. This also gives you the flexibility to dismount your iMac from the workstation and move it wherever you want.

Stand up and innovate! This sleek, height-adjustable workstation is made so that you can stand more, sit less, and become healthier doing so. The advanced ergonomics and uncompromising style of the WorkFit-A are proportioned so that your body, space and passion all function in perfect harmony.

Set up is simple. An iMac base slips easily under the WorkFit’s worksurface, which discretely and securely holds it in place. No VESA adapter is required to mount and move your iMac where you want it.

Enjoying my new work space, Jul 20, 2016
by Janet, California
I love the workstation stand. Would have picked 4-1/2 stars if that was possible. Picked 4 stars because it moves slightly to make the monitor not always completely level, but can easily adjust it. It actually gives me more workspace, sit can be pushed aside and almost the entire desktop can be used. Before the monitor took more space. Definitely would recommend it to others.

Apple Compatible Ergotron 24-414-227 WorkFit-A Sit-Stand Workstation Review, Apr 3, 2015
by Lisa J., Washington
I chose good rating, because stand makes the computer jiggle when typing, which I don't like. Other than that I love the product itself. I feel the the product is nice looking and it will last and not break down.
