Replace cushion of seat?
My '03's driver's seat is pretty worn out. I feel like a grandma looking over the steering wheel. Is it possible to replace just the foam cushion in the seat or do I need to replace the seat?

Check xtremewlr's 4runner build thread over on tacoma world, hes doing the seats in his 4runner with new leather covers and also replaced the front cushions, PN is in there. Looks like its 71501-35080

Here ya go. HOW TO: Replace Drivers seat bottom Foam- PIC HEAVY
I did it myself. Tedious but 100% worth it. Back nolonger feels funky after long drives.
Make sure you have a good pair of snips for the metal clips/rings.

Yep, I did it to mine since I was going to reupholster anyway, but once I got it apart I realized the my original cushion was actually in great condition, it was just the leather that was all jacked up. Since I spent the money, and had it all apart, I decided to replace it anyway, but kept the other one since it was still better than most I’ve seen. If anyone is interested, I still have it and will sell it reasonably. While it was apart, I also decided to get new seat heaters since the ones that I had originally weren’t working well.

The passenger side will be different since it has the air bag weight/pressure sensor in it and is not transferable to the new foam. It's actually molded into the seat foam.
This is the passenger side foam with the sensor coming out the back, the three flat cables.
The seat heaters are attached to the factory seat covers, or at least the factory leather ones. Those can be transferred over if replacing the seat covers.

Interesting, I didn't know the weight switch was in the actual seat foam itself, but I learn something new everyday! All of your pictures are great, definitely a great resource for anyone looking to swap the seat cushions and covers.

Non oem options
Im wondering if anyone has found a non OEM option. Seems like theres plenty of memory foam, pillows etc out there. I could get a mattress for about the cost of the seat foam.

I saw where a guy used a 1st gen Tundra seat foam because he could get it for less than $70. I know it fit the seat frame but not sure how the seat cover turned out going back in it.

This video (@6:55) suggests if you steam the foam it will come back to shape closer to original. I can't confirm since i replaced my foam when i did it. However, i don't see why you couldn't try this and/or add a layer or two of memory foam to the existing pad.
In any case this video was super helpful for me.
