I would not recommend for anyone my height or shorter or anyone who prefers a seat with more cushioning.

The pole does not lean easily and the seat was incredibly uncomfortable

The seat is too hard

The seat is a bit hard and seems slippery when I try to lean against it

The seat is extremely hard &

At present, if I elevate the seat my feet just hang in the air without any support

I think between the really hard seat and the very wobbly "active" base -- the stool is just a bit too active and uncomfortable

The seat itself is very hard and uncomfortable but perhaps that's how it's meant to

If you stand in front of the seat and plant your feet on the base, you can lean back on the seat (such that the seat is leaning backwards).

The seat was as hard as concrete and hurt to sit on it for more than a few minutes

This seat is very hard

The seat is comfortable and has a bouncy feel to it

I have found it to be very uncomfortable, the seat is extremely hard and my buttocks and lower back hurt after using it

I do like this chair, but, it has a rather hard seat which, over time, becomes uncomfortable.

But the seat is so hard that it is extremely uncomfortable after more than a few minutes of sitting/leaning.

If you know you want a very hard-seated, very active

I feel safe on it because my heels rest on the chair's "foot" so I'm holding it in place as I lean back on it.
