Don’t find it comfortable, and not sure why other than that it has something to do with the seat itself.  Bought another one at the same time with a less cushy, thinner seat that’s more comfortable.     I’m pretty short and it might be that my thigh ends up hitting the bottom of the thicker seat when I scoot around on them from room to room.  I broke my foot and have a knee scooter I use outside the house but find getting around on the stools to be much easier at home.   Perhaps if I used them as they’re more typically used the thicker, cushier seat would simply be an advantage
