ps my boy is a big lad and its not flimsy at all, hope this helps you choose
The pic of him with the bannana in my avatar pic is the fisherprice one and here is a link to the ikea one https://www.ikea.com/gb/en/catalog/products/00069725/ and it has only been a few weeks since we got the ikea chair and he is virtually sitting unaided
Fisher price good points = none
bad points = hard to clean, tray is really bulky and to many crevisis to clean, i mean why would a small baby need a cup holder space in the tray? massive says it folds but you cannot call what it does folding and finally i was always stumping my toes on it!
Ikea chair bad points = they dont deliver to the house and it was a treck to pick one up
Good points = nice and compact, easy to clean, small removable tray and bonus i dont stump my toes on it. You can also buy an inflatable kind of pillow thingy for when baby is unable to sit to help them stay upright but my boy was too big to use this by the time we got our chair.
Where did i hear of this chair, well my childminder was using it to feed Freddie his lunch when i picked him up early one day and i was amazed at how well he was feeding in it and how better his sitting position was, it made me realise how rubbish my fisher price hygine chair really was!
