I happen to really like the seats in the 4runner. But having installed leather seat covers and being intimate with taking them in and out and what they look like under the fabric...
I would suggest that the best option is to just have them upgraded by a good upholstery shop. They can take the covers off and add/subtract foam or even replace it with memory foam or other types. This honestly wouldn't be that hard to do yourself if you're semi-competent. You can also add seat heater pads while you're in there if you dont have them already.
