Essential if you weigh >200lbs
It's a great piece of additional support. Most office chairs have a sponge as a cushion, and for us larger folk that feels like sitting on Legos after a week or two. This cushion from Purple restores a bit of spring resistance and removes that feeling my tailbone is being crushed. Sometimes I do 10 hours in my office chair. Next to better wheels, this is the next most needed upgrade for those looking for additional seat comfort.<br /><br />It also is very ventilated in the sense that if you have a leather chair, you won't have to peel your butt from the seat, and basically eliminates the "swampbutt" that occurs in such seating arrangements.<br /><br />That alone is worth the cost. That and saving your tailbone.
