Hello all, I bought the Cybex Pallas M-fix SL (https://www.galaxus.ch/de/s10/product/cybex-pallas-m-fix-sl-kindersitz-13447421) for our first child. Can I now simply buy the Cybex Solution M-fix SL pictured here (https://www.galaxus.ch/de/s10/product/cybex-solution-m-fix-sl-kindersitz-7497656) for the second child and take the bar from the Pallas? According to the description, it seems to be possible to "convert" the Pallas into the Solution. (No, I don't want to give the Pallas to the second child :) Why? For reasons :)) Thank you!
