Query: eCommerce nightmare....

Greetings, the Safco Taskmaster is only good as an item to lean against. Using this pseudo-stool as a chair at a workstation can be dangerous due to the teeth that hold the seat to the frame can bend and have broken at the facility I work at. Namely amazon.com's Newcastle distribution center. Due to certain ergonomic issues sitting at a taskmaster for prolonged periods will reduce productivity. While increasing risk of lower back injury. There are many good choices for seating at an elevated workstation but this item is not one of them.
