durable not really on my list. i just added it in because i dunno what else to add in besides comfort.

most of the strollers or almost all the strollers are built to withstand the weight of toddlers anyway. some will withstand some heavyweight shocks, but then how often i will kena heavyweight shocks i also dunno.

lightweight is #1 as i've experienced a super heavy 4moms origami stroller and my friend's aprica before. each time i see a flight of staircase i just wish that god was helping me lift the weight. a few steps on the staircase and u would wish that u had a lightweight stroller too.

as for comfort, i think most strollers are comfortable enough. adding cushions and paddings can be done easily. but if too cushiony or too much padding, the heat will get to the baby .
