We got the king parrot, and are really happy with, we just couldn't justify the price difference, also the boori cots look was alot 'heavier' which I didn't like. I think any drop side is going to make some sort of noise, it's just a matter of bubs getting used to it. We also liked that it converts to a toddler bed. It has pretty much the same features as the boori but at a fraction of the price!
