The headrests in our 2009 Flex SEL seem quite obtrusive. My wife and I both find that they create a bit of blind spot when looking right and to the rear, and we'd be willing to replace them with something different and with a smaller, less obtrusive form factor. I saw the recommendation for Ford 500 headrests, but I am wondering if anyone has used any other??? Any from other Ford Cars? The rear seat head rests are a lot slimmer and I may try those. Any suggestions would be appreciated. This is about the only sniggling detail we've found to take issue with.
