Frequently Asked Questions
The weight capacity for the Office Master IU55 24-Seven Intensive Use Ergonomic Stool is 300lbs as recommended by the manufacturer.
Yes, the foot ring of the IU55 chair has a patented turn lock that can be turned to move up and down. It can then be locked in that position.
The IU55 has a 10" cylinder as standard. It also offers the option of an 8" cylinder for an additional price. Unfortunately, none of the high chairs (including the IU55) with a cylinder higher than 6" offer forward tilting. This is due to liability in tilt ratios. As such, we do not know of any chairs like this that would offer this sort of capability (neither that we carry or from competitors). There is one and only one exception which is a "non-traditional" seat Neutral Posture AbChair TAsk Lab Healthcare Cleanroom Stool which does offer forward tilting and can be ordered with an 8" cylinder bringing the seat height range to 23-31".

Great product for the money. Using at a work table. The options for building the chair allowed for customizing it to fit the work table. Shipping was on time.
