Don't know but am considering getting my parents to get one in case they have to take ds around and it will last for ages with him. I haven't actually done any research about them - just know they're around - don't even remember the brand

Just checked the big w site - under baby > carseats > booster cushions it has an infa-secure sunshine booster cushion - it's the sort of thing I'm trying to describe - no reviews on the big w site but if you're on something other than a phone you might be able to copy & paste the details and find a safety review on the net somewhere.
