Travel high chairs- got 2 options, which to go for?

[Haylstones]

I'm looking at 2 different ones on Ebay for ds. He's almost 6 months, very big (24lbs) and pretty much sitting unaided. ANy comments or other suggestions would be much appreciated!
Thanks
number one

number 2

don't think you'll find much between them tbh.

I had a baboz one though, which was great because it also had shoulder straps to keep them in a bit better.

like this one

either to be honest tho like ThisIsYesterdays link, shoulder straps do deter twisting about.

I think the baboz one looks better

Thanks, that's a really useful link. They both looked pretty much the same but number 2 seemed to hold the baby in a bit more securely, which is why I was confused!
I may bid on the baboz one now, ta
