Adjustable Height Ergonomic Lab Stool with Wheels

The saddle chair is designed to provide a better seating position with the knees lower than the back in a natural position aligning the back shoulders and neck. The pneumatic drafting chair is beautifully crafted with black vinyl material and comes with seat angle adjustment and height adjustment features. You can adjust the height and change the amount of force required to change the forward tilt for you to carry out lower back exercises.
