I was excited to buy this for my daughter having seen some great reviews and it seemed to have more interactive features than other walkers.It arrived today and could not have been more disappointed. I assembled it as per instructions but was dismayed to find that the activity center does not attach at all securely to the main frame. In fact it actually fell off when my 9 month old daughter grabbed the handle on the top of it when standing up from behind the walker.The features seem fine and she was really taken with the bright colours and telephone handset, but the fact that the activity center falls off at the slightest provocation makes it, in my opinion, unsafe.I have sent it straight back and will not be ordering a replacement - looking at the design I can't see how another one will be any different from this one.Such a same when it promised so much more .....
