5 Reasons to Buy

Safety and Security with i-Size

The Acorn i-Size has had extensive crash and safety testing as part of the latest R129 / i-Size standard. It is i-Size and ISOFIX when paired with the Acorn i-Size base (sold separately), delivering reduced car seat movement for total peace of mind. The Acorn i-Size car seat brings safety and security to your snug passenger. The Acorn i-Size car seat can also be fitted rearward facing using a standard 3-point seat belt.

Impact Protection

The Acorn i-Size car seat has impact and protection at the core of its design. The i-Size standard takes testing further with side impact and roll over testing, all using the latest crash test dummies, to help create safer car seats. Acorn i-Size has a reinforced construction with a strong protective shell to encase your child. To deliver extra levels of safety, the Acorn i-Size has a flip-out Side Impact Protection System to absorb force in the event of a side impact.

Transform Travel

The Acorn i-Size will transform travel for you and your baby. The easy one-handed harness and headrest adjust allows you to position and adjust simultaneously to suit your child’s needs. This seat cocoons your newborn baby with the soft, removable ‘newborn nest’.

Ultimate Comfort and Handy Extras

The Acorn i-Size car seat has been created using the ultimate high-performance, energy-absorbing materials, offering maximum protection for your baby. It comes with a UPF 100+ extendable canopy and much more. Easily removable, machine washable covers offer continual comfort.
