If you are just trying to get the seat out, you won't need to remove the seat bottom. Simply slide the seat back to remove the front mounting bolts, then slide the seat forward to remove to rear seat mounting bolts, then lift the whole seat out.
Only if you have a 2" lowering kit installed will you need to remove the seat bottom to access the bolts (2" lowering kit eliminates ability to slide seat forward). If this is your situation, you must remove the 2 screws that mount the slider lever (on front of seat bottom), then clip the 2 zip ties that hold the seat covers to the front corners of the seat bottom frame. Finally you will need to release the front seat bottom material from the frame by pulling it down and forward. It is clipped to a rail at the very bottom of the seat assembly. With the seat material released, you can lift it up and then lift the seat bottom foam which provides access to the mounting bolts.
It is simple to remove the seat without a 2" lowering kit it is really tough to do with the kit.
Oh! Don't forget to remove the seat belt loop from the upper part of the seat before trying to lift the seat out.
