Swivl-eze trouble

I dont know how long its been there but i cannot get my power pedastal to realease from it mount.Its has directions on the side saying depress latch and bump hand with other hand for quick release,not working.Ive depressed bumped beat on the side pulled my butt off and still no release.Any suggestions would be highly appreciated. Thanks in advance.John

Spray a little WD 40 around the top and then push down on the seat and while depressed hit the handle good luck.

Thank you very much.Worked great.Its out finally,i feel like i just wrestled a bear.
