Maybe we are just bad parents but have found that it didnt effect our 3 year old and our youngest who is six months has no problem. The longest they are in it is once a month for 3 hours when we drive to Norfolk and most of that time they are asleep. If we go to Bluewater etc we tend to get there, have a coffee, take her out of the seat for a feed and then put her back when we walk around.

The seat is well designed and quite comfortable, sure I wouldnt like to be in it all day but a few hours in acceptable.

BTW, check out the simularity between a McLaren at a few hundred pounds and the ?50 "own brand" model at Halfords/Toys R Us. They seem to look the same, strange that
