2020 cascadia seat won’t lock

True story; a driver I worked with had several problems with the drivers seat and company didn't do anything.
At a truck stop, he removed the seat and threw it in the dumpster, then called the company and said while he was inside the truckstop eating, someone stole the seat. Said, "I'm stuck here and can't drive the truck; what do you want me to do?"
Of course, he got a new seat. Had a new upgraded seat installed.

 

@sekhon617 look for a lever that locks the seat isolator. Most seats are designed with that 2-3” of rocking movement as it helps when you’re hauling live loads like tankers and there is a lever that will lock that function out.

 

The seat I had pulling tankers, push the lever that adjusts the seat in the opposite direction and it locks the seat. Sometimes may have to jiggle the seat a little while pushing the lever, to lock it.

 

Easiest to just start flipping the levers on the seat. That is if your seat has the isolation feature. This is what it looks like on my Sears Atlas II seat.

 

On my Freightliner, the lever on the right side locks the seat from rocking. It’s on the left as you sit in the seat and reach down.

I’m with you OP. I can’t stand the seat rocking front and back. I keep mine locked from doing that. I have a Pete 389 with leather legacy seats. I *wish* I could control the up and down spring like you can on the plastic bumper POS 579s, but the legacy seat in the 389 doesn’t have that feature.
