If you are hunching your shoulders when seated at the machine, it probably is too high and not good for your back, neck and shoulders.
You could elevate yourself with seat cushions if your chair isn't adjustable, but in doing so you may have to elevate your foot control if you're short like me.
My machine is in a cabinet and sits flush with the top. It is only about 27" off the floor. Hope you can find a solution...
