Better, more comfy front seats

[tforkner]

The front seats in my '08 hatchback aren't terrible, but they could be much better. Are there any swappable Toyota seats that are direct, no-hassle bolt-ins that offer more cushy comfort and support out there? I'm looking for something that would give better long-distance comfort. The stock seats just get too hard after about 4 hours' driving, and I sometimes drive up to 11 hours at a time a few times a year.
