Easy to use with great range. So much better than maintaining cords.

Does not work. Would like a refund for this.

The first thing i notice when initially sit on the seat is that it is cool. It does tend to sag a little in the middle after sitting for 2 or 3 hours. It's pretty comfy and holding up quite well after 3 months of almost daily use.

Gel looks cool and is cool to sit on but compresses so much that you can actually feel the chair underneath. I am not fat, but my skinny * flattens the cushion. Just yesterday noticed that the zipper does not close all the way on the pillow.

I use this thing for 2 weeks and it was worthless. Cushion lab is better. Do yourself a favor & look at something else.
