Toddler seat to booster

A 5-point harness seat for younger children, then a high-back booster. The harness stores away when you switch.

A secure double fixing in harness mode. In booster mode, use ISOFIX with the seatbelt, or the seatbelt alone.

MBCS75 adjustable headrest

The Easy Grow system raises the headrest and harness together, so it's quick to get the right fit.

Soft padded covers on the straps and a crotch protector keep your child secure and comfortable.

MBCS75 padded headrest
