Maxi-Cosi Tuva LX Harnessed Booster Seat

The Maxi-Cosi Tuva LX is our go-to forward-facing harnessed booster for reviews and real-life family testing. Designed for children from approximately 6 months to 8 years, it’s packed with safety, comfort, and convenience features, while remaining the most compact forward-facing car seat on the market.

Installing the Tuva LX is easy and secure thanks to the SMART Lock belt system, and adjusting the 9-position headrest and harness can be done on-the-go without removing the seat from your car. Generous seating space, a premium insert, and cool wicking fabrics ensure your child stays comfortable on every journey — whether it’s a quick school run or a long road trip.

With Air Protect® side impact technology and GCELL® torso protection, safety is never compromised. Practical features like magnetic harness holders, dual cup holders, and an adjustable crotch buckle make life easier for parents.
