Full disclosure: this isn’t exactly a chair. Though, you can purchase just the chair.  I’d suggest getting both to maximize the results.

The Locus combines a chair and if so desired a standing desk. The result is probably the ideal position, as it’s half standing half sitting, allowing for more motion throughout the day which is helpful for blood circulation. And because the seat is pneumatic, and at an angle, it adjusts with you as you you make micro movement throughout the day.

And another plus is that the desk portion – which can be ordered separately – has a height range of 36″ to 48″, making a number of other chairs compatible with the setup. And worry not. As the desk is controlled via a hand crank, ensuring that there is no motor to break or parts to replace.
