Here's how to calculate your seat height to perform at your best.
BioFit manufactures models in a wide selection of seat-height adjustment ranges. This choice of adjustability options helps ensure our chairs and stools fit the size and body type of individual workers and unique applications, delivering in-demand flexibility to accommodate users on different shifts or the same worker performing other tasks at different work levels.

The basic formula to calculate the ideal seat height directly corresponds to the actual work level ‒ that is, the distance from the floor to the work surface height ‒ minus 12 inches. Therefore, BioFit recommends using this figure as the mid-point of the seat-height-adjustment range of the chair purchased.

For example, a 40-inch work level ‒ the height measured from the floor to the top of the work surface ‒ minus 12 inches = 28 inches ‒ is the mid-point of the chair or stool seat height adjustment range.

This formula applies to most workers. BioFit ergonomic seating will fit 90% of workers without customization, while alterations can be made easily for the other 10%.
