We have this one https://www.toysrus.co.uk/Babies-R-...iFunction-Highchair-in-I-Love-My-Bear(0031159)
LO isnt using it just yet but my 13 month old nephew had his lunch in it yesterday, he's big for his age and there is huge amounts of room left for him to grow more!
Is quite big but really sturdy, nephew can rock his wooden one https://www.argos.co.uk/static/Prod...airs|12109165/Trail/searchtext>HIGH+CHAIR.htm but cant rock mine!
