Car seat with inbuilt harness up to 26kgs.....

[Beach Mama]

About 6 months ago or so, the Standards were changed from weight to height. So none of the seats now will mention weights, but rather shoulder height from the base. (Hence my earlier reference to the Britax seat with the longest RF they offer being a 35 or 36 cm shoulder height.)
What you are measuring is basically the height of the their shoulders from a seated base, rather than the weight of the child or the age.

Thanks hun - can you link me or PM where you got this info from please? I am just looking at the current MR user guide on the Britax site and it says to use the seat as a Lap sash or H Harness from 14kgs... ETA: Just realised that is a minimum!

At this stage we are going with either the S&S Hi-Liner or the Infa Vario Kid based on the teasing safety results. Still undecided about the H harness, am going to test a few out. As far as I can see is that they don't increase safety but are just as safe, so the question is why use one, and if used incorrectly then they decrease safety so still unsure. WOuld like to test it on the kids before we decide what to do. We need 3 seats all up as the MR we have will be ok we realised!

Just unsure what to do with my parents car - either swap cars with them, swap seats in and out all the time, or buy cheaper boosters for their car (which I don't really want to do but we can't afford 1k for 6 seats)
