> Interested in 1 please - how tiny a human would it fit?
I've done a bit of internet digging but I can't find a definitive answer, however one review says 'Designed to take kids up to 40kg (and most likely in the age range 4 - 10)'. I've just looked back through some old family pics and I can see my daughter wearing her harness as a four year old (see pic!). I think we'd moved to sit harnesses by the time they were about 9-ish.
