Is the height adjustment measurement the bottom/underside of the seat, or the top where you would sit?

The handle that you use to adjust the height of the seat is under the seat.

Lowest height is approximately 18" to seat top. Highest is approximately 23" to seat top. With the hydraulic lift, it is very easy to change height to be comfortable for the individual. Previous answer is measuring from seat bottom to floor. Guess that accounts for the difference in our measurements.

The lowest position of the seat is 35 inches. The seat can also be adjusted forward and backwards

One of the three levers on the right side underneath the seat adjusts the height. I am unsure of exactly what you mean, since the seat does not normally begin on the floor.

Without actually going downstairs to measure it - I am pretty sure, for me, the seat is regular chair height (18"). If you are shorter than me, and you are, (I'm 6'-2" so I have it all the way up) your height would be lower than that because the seat rides on an incline and you would be sending it lower. I also am old 71 and I find the machine to be quite comfortable.

No the height is not adjustable. It sets about 30 inches or slightly higher I'm guessing. Very comfortable to sit around. Easy to set up. We love it!

the seat height is adjustable, the height of the cushion is negligible unless one buys for some crazy research.

Gary - The seat height simply goes up or down with height of the support bars based on the user's height.

The chair height is adjustable with the top part sliding into the bottom part. The top 1/2 appears to be 1" and the bottom is 1 1/4"

Seat goes as low as 18" and as high as 23-3/4" (fully assembled). This measurement is for the stool that has the 4 inches of foam. I'm not sure if it is still offered that way, so I am just mentioning this.

The seat adjusts from a low of 21 inches to a high of 25 inches. You could go a little higher but it feels unstable.

At the lowest seat adjustment, you would be about 8 inches from the floor. At the highest seat adjustment you would be about 1 foot and 4 inches from the floor.

From the floor to the top of seat at the front side, the lowest is 26" and the highest is 31." The seat tilt can affect it slightly. I have mine set so I'm leaning more forward/straight than back.

At the lowest setting of the seat, measuring just in front of where the arms attach to the seat, the seat is 15 inches above the floor. Still at the lowest setting of the seat, floor to the highest point on the arms is 26-1/4 inches. That means that the seat to arm top is 11-1/4 inches (approximately). The main reason for putting the term "approximately" in there is that the seat position will vary when someone is or is not sitting in it. Also, the degree to which the seat is tilted back will have some effect on the total arm height.

The seat is the same height from the ground regardless of setting. You slide the seat backwards/forward to adjust for your height.

I measured 18" (lowest) and 22 (highest). I tried to pick the highest point of the seat (which is the sides) and not the front of the seat which is a little bit lower. Hope that helps.

From the top of the seat (where your bottom sits) highest is about 23 inches and lowest measure about 18 inches.
