Its also pretty narrow and fit in airplane seats.
If your 18 month old is 36" now even fast growing toddlers don't really grow more than 5 inches a year so you likely will make it to 2.5 yrs in the Contender. Also at some point their legs grow rather than their torsos and that helps too, so you might make it longer.
