All Heavy Duty, from under the seat to the floor
Intensive use and heavy duty weight usage hardly describe the engineering and manufacturing quality found throughout this entire assembly. Perfect for virtually any large person who has previously experienced failure of component parts due to heavy use or heavy weight in an office swivel chair.
The kit (#7401KM) assembly is complete as shown below, with nothing else to purchase except perhaps the mounting #6090S screws. Shipping cost is reduced and ensures safe arrival by packaging into 2 cartons. No special tools are needed for assembly, only attaching to the chair bottom. Simply inserting the threaded post (spindle) into the base connects all the component parts together. It doesn't get any easier than that!

The base only, may be purchased separately. Base only includes 5 Large (2 3/8") Black Castor's 100 lb load each and center column. Ready to accept your existing mechanism 1" threaded spindle.
