Thanks Isolabella, I've had a look at the Britax website. Is the new maxirider the Easy Adjust? They look good. We do currently still have the slumping issue with DS as he still falls asleep a lot. We've been putting whichever child is more likely to fall asleep (usually DS) in the compaq if its a particularly long drive... I have also heard better reports on the new style seat. I shot them off an email about the foam as well

Would you not recommend the ezycombos? This is not the greatest reason but cost will be factoring in. DH is quite happy to move the seats from car to car, and I don't trust either of our installations 100%. He'll be more likely to go for buying new seats if its going to cost $400 rather than $1000....
