I need a stroller that closes very easily and is very compact for car and plane trips. I already have a Bugaboo Chameleon which is not practical.
From your choices, the by far best one is the Joolz Aer. The tallest seat back, and overall well made. The Yoyo's crazy slanted and very short backrest will not last you that well, even if it's a sturdy stroller, and the TRVL also is not that spacious, nor that high quality to be worth going for. Apart from the Aer, check the Bugaboo Butterfly, also a whoppingly high backrest and a well made ultra-compact. Those would be my best choices.
