I like the Ikea chair too, my parents have it, but:
- my niece was able to wiggle one leg out pretty easily at one point (not sure what age). It wouldn't be one you could ever walk far away from.
- my MCHN pointed out that it only has a 3-point harness and that the way the straps dangle at the back make it possible for a child on the floor to get tangled up in them. She knew of a boy who had done so and nearly strangled.
So, if you get it, make sure you tie the straps up at the back so they aren't a hazard (this would go for any similar chair). And if you have a real escaper for a baby you'll need to watch them closely (but I think that would go for many chairs, including the one I bought too).
We have one that is like the Ikea one, but not identical. I think it's an Inglesina, got it from Baby Bunting on special for $99. It's got an orange cushion, which is basically why I got it: my
DH loves that colour. You can now get a cushion for the ikea one, too. One good thing about the Inglesina one is that the legs come off and the chair part stands alone, so you can use it as a chair on the floor (and ok, I'll admit it, I used it on a table when
DD was smaller, not moving away, mind you). I put
DD in it, for very short periods of time, from about 3.5 months, as she was wanting to be sitting up, propped, to see what was going on.
