Compact designs
Travel-focused strollers often prioritise folding and carrying. Compare seat configuration, storage access and wheel behaviour on your actual routes; a category name does not guarantee airline acceptance.
Full-size designs
Everyday strollers may provide more configuration choices or a different wheel footprint. Compare the folded package as well as the open stroller, especially when you use stairs or small lifts.
Expandable designs
A platform may support extra seats only in specified combinations. Price the complete configuration and use the exact compatibility chart. Do not assume every seat can occupy every position.
