The expensive things, compared on what's actually different. Every figure in every table comes from the manufacturer's own page, with the source listed.
Four infant seats compared on the things that decide it: what the carrier weighs, whether it installs without the base, and which stroller it clicks into. Every figure from the manufacturer's own page.
Eight strollers compared on the questions that decide it: does it take your car seat, does it become a double, what does it weigh, and does the fold fit your trunk. Every figure from the manufacturer's own page.
Eight monitors compared on the number the box hides: what the subscription costs after you own it. Plus what each one actually tracks, and when an eighty-dollar screen is the honest answer.
Nine cribs compared on the things that actually differ: what the conversions cost, what the wood is, and whether the kit is in the box. Every crib sold in the US meets the same federal safety standard — so this table is about everything else.
