This topic came up in another thread, but I thought it deserved its own thread.
I use as a research tool. On the compares pages, several seats are listed as not having SIP. Even several popular Britax models. What standards do they use? Another poster told me any 5-pt harness provides this safety feature.
I'm going to try to contact the site itself, but I wondered if this might be quicker.

"side impact protection" is a somewhat meaningless term in the US since we have no official testing standards or independent agencies that test for it! Some companies list 'side impact protection' as a feature but we really have no way to determine what exactly that means.

In general, a seat with a five point harness, deep plastic shell or headwings, and EPS/EPP foam will provide side impact protection, regardless of whether or not it's marketed that way :thumbsup:
