According to the National Center for Health Statistics, the average American adult spends an unhealthy 6.5 hours a day sitting. If sitting is the new smoking, as has been said, then the first place to amend our sedentary ways is at work. A variable-height desk allows you to change from sitting to standing at the press of a button. Intermittent standing takes pressure off your spine, improves circulation, and reduces the risk of obesity, diabetes, and high-blood pressure associated with inactive lifestyles. Here are a few features to look for when trying to get back on your feet during the workday.

Free Standing

If you want a desk that can convert from a sitting to a standing position, consider one with motors to make it easier to change back and forth. Seville

A standing desk with integrated lifts eliminates the need to buy a separate table or work surface. If you opt for a one-piece design, be sure that both the lowest and highest settings will accommodate your personal height and stance.

Large Work Surface

Make sure the working space is large enough for your needs before buying a standing desk or riser. VIVO

Desk toppers or “risers” sit right on top of your existing desk and allow you to adjust the height with either electric or spring-assisted lifts. The work surface may be smaller than your current desk, so make sure it will meet your space needs, especially if you work with dual monitors.

Fine Adjustments

Many standing desks can be adjusted in small increments which means you can dial in to a specific height that’s perfect for you. VARIDESK

Many standing desks are infinitely adjustable; they can be set to any height within their range. As long as they have locking adjustments every half inch or so, you should be able to find just the right height for comfortable standing.
