Trip Trap vs Hauck

[Wiggy29]

I'm after the style of high chair that grows with your child. I'm trying to be more sustainable so was hoping to find a second hand trip trap one but none seem to be coming up near me on ebay. I noticed that this Hauck one is made from sustainable European wood:

Any thoughts on it or am I better holding out for a trip trap (DS already six months though and currently feeding him in his bumbo but it's not ideal).

We have a hauck each for DS1 (3) and DS2 (19mo). DS1 in the normal chair position DS2 as highchair. We have been really pleased, it puts them in a good position at the table, easy to clean and not too bulky.
For use as a high chair, we have attached a harness though (from reins/harness set) as DS2 can otherwise climb out
