But also negative to report:
After early as 2 weeks creaks the rocker. So if you change from an upright position in Rear-facing position or vice versa, it creaks very clear.
Anyway, are chairs, where only the backrest moves much better (but more expensive), but I already knew before buying.
Another shortcoming I find, is the high seating position. Little people will have problems even in the lowest level. I would say in "normal height" under 170cm height of the chair should definitely be tested extensively to the effect.
