Very much NOT wanting to open a forward/rear-facing debate thread (I've read that many that I'm absolutely sick of them!) - here's a good price on a Group 0+ and 1 car seat which can rear-face up to the 18kg weight limit in principle (this sets it apart from options like the Britax First Class plus which only rear-face up to 13kg). I say 'in principle' since I've read that (as with the other Joie forward and rearward seats) the available legroom when rearward facing may mean the child needs to face forward a bit earlier than 18kg. I'll have to wait and see.
Now that my daughter's growing out of her group 0 seat, I've been spending far too long in the minefield that is child car seats. Very difficult not to get dragged into what seems to be a strangely emotive debate! Trying to cut through all that, I eventually settled upon this model based on my requirements for:
i) Something that could be removed and reinstalled fairly quickly/regularly
ii) Suitable for cars without Isofix
iii) Rear-facing for the foreseeable future but with the option of forward-facing if daughter really doesn't get along with rear-facing as she gets older.
The Joie Stages is also an option at the same RRP of £130 and lasts longer but it is a bigger seat and one of our cars is quite small in the back. Also the Stages doesn't have a seat belt lock-off when rear-facing, whereas the Steadi has dual lock-offs, which I think seems to make the fit of the Steadi feel more secure. I think I found out somewhere that the recline options are better on the Steadi than the Stages, but I can't be sure - certainly the Steadi reclines quite a lot.
The Glasgow Pram Centre seems to be the only place that has reduced the Steadi at all, and so £104.99 looks a good price. I was told that stock of the car seat might be a couple of weeks coming in, so I got Precious Little One (http://www.preciouslittleone.com/product-information/36/33889/joie-steadi-group-01-car-seat-(black)/) to Price match and with the refund of 10% of the difference, their price became £102.49. But it seems that Precious Little One are also now waiting for the next stock of the Steadi too.
So in short, I haven't seen anything comparable to this for a hundred quid, but I'd be glad to hear of any other options (especially with a second little one on the way...)
