The Nitro offers all the same features as the Mac Saddle, but instead of a threaded height adjustment, Nitro has a nitrogen gas shock. This adjusts height to within a fraction of an inch with the touch of a finger. The gas shock also adds just a little bounce or "give" to the seat, like an office chair.
Nitro Throne is now available in a taller, extended version which has a seating range of 23" to 29" high.
