All about me

With simple good looks as standard, the Aton B 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 11-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.

For superb safety, the Aton B i-Size uses the Linear Side Impact Protection System (LSP) which absorbs the forces of a side-impact collision in a linear series of reactions through the use of the shoulder and head protectors. Whilst that happens, the kinetic energy of the body caused by the impact is absorbed in a very early stage of impact and the head is actively led into a safe position. Now that's super safe! To keep your little one comfortable as well as safe, the harness has soft belt and crotch pads, and an XXL sun canopy which 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 modular M-Line system, meaning you can use it with the Cybex Base M system for true i-Size safety. The Base M can also be used with the follow-on seat, the Sirona M2 i-Size so you only need one base for both seats! The Sirona M2 i-Size is sold separately. The Aton B 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.
