Heavy Duty / 24-7 Rated
These heavy-duty stools are rated for at least 300 lbs. and have a 24/7 stool class. This class includes heavy-duty drafting stools (with/out wheels) that are rated for 24/7 use - more than the 40-hour work week. Most extended height chairs or stools in the marketplace carry weight limits of 250 lbs. and their warranties cover 40 hours per week of use. Our line-up of heavy-duty lab stools found here are rated for at least 300 lbs. and many carry the 24/7 around-the-clock certification as it applies to the factory warranty.
