Doona X Car Seat & Stroller

by Doona · Babesta Pick — The Next Generation Car Seat with Wheels, Built for NYC Families

NOTE: More to arrive late August into the Fall 2026. PRE-ORDER means expected delivery in August/September (including the Nitro Black); if they come earlier we will ship them out on a first come first served basis.

The Doona X by Doona is the next generation of the Doona+ — the world’s first fully integrated car seat and stroller — and it raises the bar in every meaningful way. The same click-and-go convenience that made the original a cab-life essential is now paired with three recline positions in stroller mode (Sit, Relax, and full Recline up to 159°), a patented shock-absorbent mechanism for a smoother ride, and certification under FMVSS 213B, the latest and most advanced US car seat standard. For NYC families who live by the rideshare and want the most capable version of this concept, this is it.

Like the Doona+, the Doona X is not a stroller per se. It’s a rear-facing infant car seat with integrated wheels that transforms from car seat to stroller in seconds — no transfer, no unclipping a sleeping baby, no separate frame to carry. What’s new is the comfort story in stroller mode: the full recline allows a newborn to lie flat while you’re walking, which is a meaningful upgrade for longer outings. The adjustable headrest grows with the child without rethreading, the handlebar has two height positions with a faux-leather cover, and the LATCH Base with its click-in/click-out system makes vehicle installation straightforward and secure. You’ll probably still want a dedicated stroller for longer days out — the Doona X is the setup for the weekend in Miami or jetting around town..

Best For/Not For

Best For

•      NYC cab and rideshare families — baby stays buckled and undisturbed between car and sidewalk, with no transfer required

•      The newborn stage (up to 30 lbs) when outings are frequent and the three recline positions allow baby to rest comfortably in stroller mode

•      Frequent flyers with infants — FAA approved for use on aircraft; converts to stroller mode in the airport

•      Families who want the most advanced version of the Doona concept — FMVSS 213B certification, shock absorbers, full recline, and improved harness system over the original Doona+

•      Parents who want a car seat that doubles as a stroller for outings without carrying a separate frame

•      Urban families who take more cabs than subway rides with a newborn

Not Ideal For

•      Full-time stroller replacement — most families pair the Doona X with a dedicated stroller for longer days out

•      Babies over 30 lbs or 32 inches — at that point it’s time to transition to a convertible car seat and a dedicated stroller

•      Subway-primary families — at 19.6 lbs the Doona X is heavier than most travel strollers and not optimised for subway stairs

•      Jogging or rough terrain

Who Is This For and How Long Will I Use It?

Newborn to 3 Months

This is where the Doona X is at its most useful. The cab ride home from the hospital, the first pediatrician appointments, visiting friends — the ability to move from car to sidewalk without unclipping a sleeping newborn is genuinely valuable in the earliest weeks. The full recline in stroller mode (up to 159°) allows baby to lie flat while you walk, which is a meaningful upgrade over the original Doona+ for longer stroller stretches. Note: recline is available in stroller mode only — the Doona X cannot be reclined when installed as a car seat.

3 to 6 Months

Still ideal for shorter outings and cab rides. As baby becomes more alert and outings get longer, many families start using a dedicated stroller for longer days while keeping the Doona X for all car and cab situations. The three recline positions continue to offer comfort flexibility as baby grows and becomes more alert.

6 to 12 Months (until weight or height limit)

The Doona X continues to serve as your infant car seat — in the car, in cabs, and in stroller mode for shorter outings. Most families transition to a convertible car seat and dedicated stroller around 12 months or when baby reaches the 30 lb or 32-inch limit. The Doona X is a first-year product, and one of the best available for families whose daily life involves regular car or cab use.

Is It Good for NYC / City Use?

For the right NYC family — specifically one whose primary transport with a newborn is cabs and rideshares — the Doona X is the most capable version of the most practical product in this category. The transfer problem is real and the Doona X eliminates it entirely: click, roll, go. The pull-along mode handles tight spaces — a crowded elevator, a narrow restaurant entrance, a packed sidewalk — and the faux-leather handlebar with two height positions is a notable upgrade from the original for taller parents.

Where it is less suited to NYC life is the subway. At 19.6 lbs it is heavier than most travel strollers, and the fold is not optimized for rush hour on the 2/3. For subway-primary families, a lightweight travel stroller is the better daily choice and the Doona X serves specifically for car and cab situations. Many NYC families own both — the Doona X for the first year of cab rides and flights, and a dedicated stroller for everything else. Compared to the original Doona+, the Doona X adds the three recline positions, shock absorbers, the upgraded FMVSS 213B certification, and a more refined handle and harness system — meaningful improvements for families doing this daily.

Frequently Asked Questions

What is the difference between the Doona X and the Doona+?

The Doona X is the next generation of the Doona+. Both are rear-facing infant car seats that convert to strollers in seconds. The Doona X adds three recline positions in stroller mode (up to 159° full recline), a patented shock-absorbent mechanism, an upgraded adjustable headrest, a two-position faux-leather handlebar, and certification under FMVSS 213B — the latest and most advanced US car seat standard. The original Doona+ met the earlier FMVSS 213A standard.

Can it recline when installed as a car seat?

No — the three recline positions are available in stroller mode only. The Doona X cannot be reclined when installed as a car seat in the vehicle. This is an important distinction and is clearly noted in the product specifications.

Is the Doona X a stroller or a car seat?

It’s primarily a rear-facing infant car seat that converts to a stroller in seconds. Think of it as a car seat with wheels rather than a stroller with a car seat function. It’s suitable from birth up to 30 lbs and designed for the first year. Most families pair it with a dedicated stroller for longer outings.

Can I use it from birth?

Yes — the Doona X is suitable from birth (minimum 17 inches / 43 cm) up to 30 lbs or 32 inches. The three recline positions in stroller mode allow baby to lie flatter than the original Doona+, which helps on longer stroller stretches. Consult your pediatrician with any questions about outings with a very young baby.

What are the three recline positions?

Sit, Relax, and Recline — with full recline up to 159°. These positions are available in stroller mode only and allow baby to move from an upright seated position to a near-flat recline for sleeping or resting during longer outings.

Is it FAA approved for use on planes?

Yes — the Doona X is FAA aircraft approved, making it a practical option for families who fly with an infant. It functions as the car seat on the plane and converts to stroller mode in the airport. Always confirm current airline policies before travel.

Is it suitable for the subway?

It’s not optimized for subway use. At 19.6 lbs it is heavier than most travel strollers, and the fold is better suited to cabs, rideshares, and car travel. For subway-first families, a lightweight travel stroller is a better primary choice — and many families own both.

Does it work as a full-time stroller?

It can be used as a stroller for shorter outings but we don’t recommend it as a full-time stroller replacement. Most families pair it with a dedicated stroller for longer days. The three recline positions make it more comfortable for longer stroller stretches than the original Doona+.

How does the LATCH Base work?

The included Doona X LATCH Base installs securely in your vehicle using the LATCH anchor system. It features a height-adjustable support leg, a built-in leveling system, and color indicators to confirm correct installation. The click-in/click-out system allows smooth transitions in and out of the car without removing the base each time.

Can I try it in person?

Yes — come see us at Babesta Tribeca, 56 Warren Street. Our team can walk you through all three modes, demonstrate all three recline positions, show you the LATCH Base installation, and let you feel the fold and the shock absorber difference for yourself.

Can I add this to my baby registry?

Yes — the Doona X is a top registry pick for NYC families who rely on cabs and rideshares. A Babesta registry comes with exclusive perks and services, and our team can advise on which stroller to pair it with based on your lifestyle.
