Yeah, sure.

Wouldn't you feel like a real asshole if your kid died because you were too cheap to buy another car seat? I would.

I used both of my Britax seats beyond the expiration dates and they were fine. I had the marathon and the frontier.

Is this seriously something to risk? I think 6 years is a good amount of time to get out of something. Its not like they are saying yearly or anything. 6 years seems reasonable.

Does it really break down? I thought plastic could last for thousands of years.

The date is on each seat (not just britax.) molecular breakdown of the plastic.

When does my seat expire? The service life for BRITAX infant car seats (including the base), older convertible car seats, youth seats (such as the BRITAX REGENT), and belt-positioning booster seats is 6 years from date of manufacture. BRITAX convertible car seats manufactured after June 2010 (excluding the Classic line) have a service life of 7 years. Britax Harness-2-Booster seats including the PIONEER 70, FRONTIER 90, and PINNACLE 90 have a service life of 9 years. To prevent injury due to deterioration or hidden damage, do not use child restraints or booster seats older than their service life or if it has been in a moderate or severe crash. You can find the date of manufacture on the child restraint/booster seat serial label.

Britax says 6 years.

I remember reading an article that said they are fine for 10 years, but now I can't find it. Anyone have any info?
