Callisto T 360

Cybex, All-In-One Convertible Car Seat: Birth to Booster

The Callisto T 360 by Cybex is an all-in-one convertible car seat built to go the distance: from newborn up to approximately 10 years old, 4 lbs. up to 120 lbs., and up to 57" in height. At its core is a patented steel-reinforced, one-piece structure that integrates seat and base for exceptional strength and crash performance. It offers 360° rotation in any recline position and rear-facing use up to 50 lbs., with an intelligently designed harness that simplifies securing your child while maintaining a protective fit.

For city families, a seat that genuinely covers birth through the booster years means fewer re-purchases and fewer re-installs as your child grows, which matters when you're working with one car, a rotating cast of car seats between grandparents' cars, or an occasional rental. The 360° rotation makes loading and unloading easier on a curb, in a parking garage, or anywhere else space is tight.

Specifications

Best For/Not For

Best For

•          Families who want one seat to cover birth through the booster years without buying multiple car seats along the way

•          Anyone prioritizing structural crash protection, with a reinforced steel frame, anti-rebound base, and linear side-impact protection

•          Parents who want extended rear-facing riding, up to 50 lbs, before transitioning forward-facing

Not Ideal For

•          Families who don’t have cars.

•          Families with vehicles where interior width is extremely tight; at 19.5" wide, measure your back seat if you're planning a 3-across setup

•          Families who want a seat that detaches from a stroller-compatible base; this is a convertible seat, not an infant car seat

Is It Suitable for My Baby's Age?

Newborn (0–6 Months)

Yes. The Callisto T 360 accommodates children from 4 lbs., making it suitable from birth. Rear-facing installation with 360° rotation makes getting a newborn in and out easier during the early months.

Infant / Toddler, Rear-Facing (up to 50 lbs.)

The seat supports rear-facing riding up to 50 lbs., well beyond the point most children reach a rear-facing height or weight limit in other seats, allowing for extended rear-facing use.

Toddler, Forward-Facing

As your child grows past the rear-facing limit, the seat converts to forward-facing use with the same QuickSpring Harness and 5 recline positions.

Big Kid / Booster (up to 120 lbs., approx. 10 years)

The Callisto T 360 is designed to carry a child all the way to approximately 10 years old and 120 lbs., covering the booster stage within the same seat.

Is It Good for NYC / City Use?

Installation is designed to be fast: fasten the tether, route the seatbelt through the guide, click, and close the SafeLock door. That matters in the city, where a car seat often moves between a personal car, a relative's car, or a rental rather than staying installed in one vehicle. At 19.5" wide, it's comparable to other premium all-in-one seats in this category, though not the narrowest option on the market.

For comparison, the Clek Foonf is narrower at under 17" wide, making it a stronger pick for parents who specifically need a 3-across fit, but the Foonf tops out at 65 lbs. forward-facing and doesn't extend into the booster years the way the Callisto T 360 does.

Why Babesta Carries It

As a curated store, we don't carry everything. We chose the Callisto T 360 because it solves a real problem for city families: needing one seat that's genuinely safe and genuinely lasts, from a newborn's first ride home through the booster years. The steel-reinforced one-piece construction and 37% crash safety improvement aren't marketing footnotes to us; they're the reason it earned a spot on our floor.

This is perfect for our families who have a car in the city and want to purchase one-and-done when it comes to car seats. Many may still have a taxi seat in their apartment (like the Doona X and the Pico) but for their care, they know they’re set.

The everyday details matter just as much in a city context: 360° rotation for tight curbside loading, installation that takes seconds rather than minutes, and extended rear-facing capacity that lets you keep a child safely rear-facing longer without switching seats.
