I have a Mamas and Papas Prima Papa high chair. I got it because it was suitable from 4months, and I had the oppurtunity to buy it second hand of a work colleague. However I am not particuarly happy with it.
These are the things that I am unhappy about and I would recommend looking out for.
I need a screw driver and pliers to remove some of the straps.
You can't remove the padded covering without removing the straps, and a lot of food gets trapped in the folds.
The tray is too high - even now.
Bulky so not practical to take with us.
However the good points are:
Tray is completely removable so we can use it with the dining room table.
The tray has a removable top to make it easier for washing.
Very sturdy.
Solid crotch support, so no danger of them sliding forwards while you are doing the straps up.
