All about me

With stunning good looks as standard, the Aton Q i-Size offers a removable seat insert that ensures a near-flat lying position which is superb for premature and newborn babies and because the head and shoulder protectors are height adjustable to 8-positions allowing the infant carrier to grow with your child and afford them extra space, this superb seat lets your little one stay in the safest position to travel-rear facing- up to 15 months. That's an extremely long usability for a seat of this type!

For superb safety, the Aton Q i-Size uses a Telescopic Linear Side Impact Protection system (LSP) which can be easily and individually adjusted. Simply extend the side projector on the side nearest the door of the vehicle, and in the event of a side-on collision, the forces are transferred by the side protector and distributed through the car seat's shell instead of to your child. The flexible material and structure of the seat then absorbs the forces of the impact and channels them away. Now that's super safe! To keep your little one comfortable as well as safe, a softly padded, extra-wide Y-shaped harness with a soft belt and crotch pads, and a fold-out XXL sun canopy which can be extended incrementally and offers UPF50+ protection against harmful sun's rays are also integrated into the solid seat shell. The covers are removable and machine washable at 30°c for your convenience.

This lightweight seat is suitable for use in the Base Q-Fix system, meaning you can use it with the Cybex Base Q-Fix system for true i-Size safety. The Base Q-Fix is sold separately. The Aton Q i-Size is also compatible with the Cybex & GB buggies and strollers as well as a number of other popular brands so you can use it as part of a travel system.

The Aton Q i-Size seat is also available in a premium range of 'Plus' fabrics, which are an exclusive, very hard-wearing fabric with a twill effect in a denim look.

Please note, the seat is ONLY i-Size when being used with the Cybex Base Q-Fix (sold separately). It can be fitted using your vehicles 3-point seatbelt, but in this mode, it is only compliant to the safety standards set down in the R44/04 regulations so it is recommended that it is used with the Base M for maximum safety.
