I worked last evening to remove the rear seat from my 90 240 Sedan. It liked to have killed me (90 deg, 90% humidity).

Seems a 240 sedan would make a great drug runner car as the rear seat is next to impossible to remove! I believe most police would just send you on your way if they had to remove the seat to see under it!

I am posting this in hopes someone might benefit. I finally got the seat loose by using a 5 inch by 8 inch piece of 1/4 inch plywood to push the seat frame steel wire back from the attachment points in the front.

Rear seat removal 240 Sedan

1. Drink lots of fluids if it's hot as this is a very physical job.

2. Pull the carpet out from under the seat in the front immediately behind the front seats on both sides. Lift the seat and look under it to see how the steel wire frame of the seat connects to the car body.

3. Other posts say lift up on the seat while pushing back on the seat. This will not work on a 1990 model. You must push back and down some because the connection point has a curl in it on the body of the car.

4. I used the piece of plywood to push back on the wire frame while also putting some downward pressure on the seat until it clears the body connection and then lift up, but if you try to lift up initially you are working against the connector which curls around the seat frame wire.

5. After both sides are free you must free the seat from the remaining connector at the rear center of the seat. With both front sides free you can raise the seat and see how the single, rear center connection works. Basically, the seat frame wire has to be pushed back to clear the connector.

Hope the helps. I simply couldn't get it to work until I used the piece of plywood.

Here are some photos http://www.brickboard.com/RWD/index.htm?id=828145&show_all=1 of the connectors but on my 1990 the front connector is much more curled so it's not simply back and up but more down, back and then up to free the frame wire from the front connectors.

Hope the helps. I simply couldn't get it to work until I used the piece of plywood, which pushed back on both wires at same time. Who ever designed this didn't think we would ever want to take the seat out, I am pretty sure.

Just took mine out of a 93 sedan. With the immense help of posted photos and other's turmoil, this is how I did it. The whole thing took about 3 minutes.

1. Slide both front seats up as far as they will go.
2. With the big seat-back adjusting wheels, lean/tilt the front seat backs as far forward as they will go.
3. Pull down the center arm rest so you can get some more room between the rear seat back and the bottom cushion.
4. Stick your hand in there and free up the center bottom of the cushion from that clip and pull the seat up a bit. ( You can feel exactly what's going on, the hook/clip is right there).
5. Now wedge yourself behind the driver's seat and kind of kneel down on the bottom cushion and push back with your knee while you're pulling/wiggling the bottom cushion up and back from the rear.
6. Do the same thing on the other side.

LIke I said, the whole thing took about 3 minutes...and the blood, sweat, and tears of those that came before me.

Hmmmm, kind of complicated. The technique I use is to reach in at the upper seat/lower seat juncture and pull the back end of the lower seat up and out (toward front of car). There is enough spring action that the seat is not hurt. From there it is simple to unhook the lower seat. Bend the tabs holding the upper seat at the bottom and pull it out and up. Takes about 60 seconds for each section.
Now, those darn locking side pins on the 245 seat back are the ones that kill me in the heat.

Good post - this task kills me every time.
