Do you have older children that may get up and rock in the chair? I'd be concerned that the baby might be crawling on the floor and get his/her fingers pinched under those blades. The gliders are a little safer in that respect. Just something to think about!
I really like it, although the price seems really high. Looks way better than the glider chairs. I'm not a mom so maybe I'm just dumb, but I don't see it as a safety hazard.
