Amazon.com : Britax Child Tray for Single B-Agile, B-Free and Pathway Strollers, Black : Baby Product Features Fits only Britax Double B-Agile Strollers manufactured after December 2013 Our favorite infant car seats in each price category (Graco, Britax, Chicco, Cybex and more), which strollers they go (nicely) with and how to install a basic seat. The britax B-Agile is a rock star among singles. We have bought 7 different strollers so far, and currently still own 5 with the quest to make it easy for my wife to deal with two boys, 15 mos apart. The Mamas & Papas Armadillo Flip is a luxury lightweight stroller with the reversible seat and the world’s most compact fold. See why I gave it a perfect score. .
