Best bouncy seat for a big 5 month old

[thecatsminion]

I got DS a cheap wee bouncy seat when he was born. We've got a lot of use out of it. He can't support his back fully but can lean forward and I'm a bit worried he will flip it over one of these days, and he is getting too tall for it.

Can anyone recommend a good bouncy chair that will do him for a long time? He's in the 90th percentile for length, so we're ideally looking for one that will do a tall baby for as long as possible.

I'd like to know this too, as DS is 6 months and too big for his bouncer, but I want to leave him somewhere safe when I nip to the loo or answer the door.

I think the baby bjorn is the most suitable as its up to 2 years, but I've not tried it.

Fisher Price do a birth to toddler rocking seat, it's a lot cheaper than the baby bjorn one.
