How the Doona X Car Seat & Stroller installs
Lower anchors
LATCH base included. Check your vehicle manual for which seating positions have anchors, and switch to the seat belt once the child passes the anchor weight limit in the manual.
Recline
No recline in car seat mode. The recline angle is what keeps a young baby’s airway open, so set it before tightening the install.
Every install is a fit between one seat and one vehicle. Read both manuals, and use a free inspection station if anything is unclear.
Will it fit your car?
At 17.3 in at its widest, this seat is one of the narrower ones in its class and is a candidate for three across in many mid-size cars. It weighs 19.6 lb, which matters if you will move it between cars or carry it through an airport.
Check your vehicle manual for lower anchor positions and any head-restraint rules.
Rear-facing seats need front-seat room: try the install behind the driver before you commit.
Certified for aircraft use, so it can travel as a seat rather than checked baggage.

No campaign in the current NHTSA child-restraint data names this model family, and I have not run a separate review for it. Check your seat’s model number and date of manufacture before use.
Weigh and measure your child. The limits above are the manufacturer’s, and a child has to meet all of them for the mode they will use.
Confirm the exact version. Colors, retail exclusives and model numbers change limits more often than you would expect; Doona lists 5 colors of this seat.
Read the manual before you buy, not after. It is linked above and holds the fit rules, the install methods and the expiry.
Check recalls by model number and date of manufacture, and register the seat with Doona so you hear about the next one.
