We got a baby elegance chair for the same reason, it has a newborn attachment and was a lot cheaper than the Tripp trapp, we’ve only used the newborn seat so far s can’t comment on the 6m+ attachment but it looks good xx
We have the mamas and papas snax still from our first. That style are all pretty much the same. I really like that the tray comes off at the front (wouldn't recommend one that swings overhead), the leg post, and the extra tray cover thing. It is also easy to buy replacement parts.
Long back and comfy padding too!
Hauck alpha because it had the bouncer seat and turns into an adult chair. Lots of add ons available like play tables etc
We got the tripp trapp because it had a newborn attachment that we have used a lot! It's well made and lasts through their life. However, it is pricey! They seem to keep their value on resale though.
