I found the regular seats were quite comfortable and likely quite acceptable. However, I tried sitting in the NextGen seats for comparison. Definitely more side bolster support, but I didn't feel much difference under my butt or behind my back. I've seen many cars with the exaggerated side bolsters like the NextGen's and they've typically shown more wear than regular seats, caused by the in/out rubbing. I've also broken a few cell phone belt clips over the years, when they get caught on the side of the seat. I was careful getting into the NextGen seat, but my phone still managed to bind a little. So, I'm wondering whether there is any benefit to changing my order to the NextGen seats. I'm thinking they'll be more of a nuisance than they're worth, unless I decide to start slaloming the car...! Has anyone seen a real benefit to them, beyond 'they look better and fit snugger'? I think I'm happy with the regular ones, but I'd like to hear if there is something I'm missing here!
