Advice needed on the use of built in childrens seats on the second row individual seats

[Borris]

Can anyone please give me any advice on the conditions/limitations/use of the built in child seat element (if fitted), of the lift out individual rear swivel seats?

I have a growing gaggle of grandchildren ranging in age from one month to thirteen years and would like to know what the maximum and minimum weights, heights etc that apply when using these built in seats. Whilst the youngest and oldest will obviously not be using these child seats I would like to find out which of the other six inbetweeners could.

I have searched both this forum and the web and I have found nothing so far.

I don't currently have these seats but am looking into their possible use.
