Meet the only car seat base you'll ever need. Designed for busy families, this modular base gives you full flexibility: rear- and forward-facing travel, compatibility with three different seats, and use from newborn through age seven.
It's built to last, straightforward to install, and makes every car trip easier. Switch directions and use the same trusted foundation for rear-facing safety in the early years and forward-facing comfort as your child grows. Easily rotate the seat toward the car door for fast, stress-free loading and off-boarding, especially when you're juggling a baby and bags. Make car travel easier, safer and more flexible. One durable base. Countless journeys.
Freedom of choice
One base. Two directions. Up to 7 years of flexibility. The Platinum S-Line Modular System grows with your family from birth to approximately 7 years while allowing you to keep using the same Base S. Start with the Cloud S infant car seat, then choose the Sirona S for extended rear-facing travel or the Anoris S Airbag for forward-facing protection with integrated full-body airbag technology. Whichever path you choose, you benefit from exceptional safety, seamless compatibility and long-lasting value.
360° rotation
The Base S offers smooth single-hand rotation, 180° for Cloud S and Anoris S Airbag, 360° for Sirona S, so parents can board and off-board with ease while juggling a baby and bags. One-handed operation and gentle side-entry make loading easier for both child and parents, reducing awkward lifting and making it easier to position your child and secure the harness correctly.
LED safety indicators
A car seat can only protect if it's set up right. The onboard safety assistant of the Base S helps you install the seat and get your child secure every time. LED indicators show the status of the ISOFIX, load leg, impact shield and battery. Check that your child is safe at a glance and start your drive in confidence.
Made to last: newborn to 7 years
Safety that stays with your baby from birth until around 7 years old. Easily switch between the Cloud S infant seat, the unique forward-facing Anoris S Airbag and the rear-facing Sirona S. All car seats grow with your child. Built with durable materials and smart engineering for lasting strength through daily use and multiple kids. Ideal for parents seeking a safe, quick-to-install, and easy-to-use long-lasting car seat solution.
ISOFIX easy installation
Base S makes car-seat installation fast, safe and stress-free. It uses ISOFIX anchors and a height-adjustable load leg for a rigid, stable connection and reduced movement in a crash. Parent-friendly, colour-coded ISOFIX release buttons and clear indicators guide quick, reliable setup—secure your seat in minutes with confidence.
Safety:
Under no circumstances should a rearward-facing car seat be used on a passenger seat where there is an active airbag.
Correct fitting of all car seats and boosters is of paramount importance in making them the most effective in the event of an accident. Not all car seats fit all cars and it is important to check for fitting suitability on all cars you intend to fit the seat to, as well as re-checking if you change your car.
Always read the instruction booklet that comes with your car seat to achieve a safe and correct fitting, retaining the guide for future reference. We recommend fitting your car seat in advance of first using it.
We recommend that babies shouldn't be left in car seats (infant carriers) for prolonged periods.
Suitability:
- Please make sure that you check the car seat you choose is suitable for your car before ordering. This can be done in store with a Partner or on the car seat manufacturer's website.
- Some of our shops offer a car seat fit test, where a Nursery advisor will test the display model in your car to check that it will fit properly. Please contact your local shop to see if this service is available. Alternatively, please contact the car seat manufacturer who will be able to advise whether their model will be suitable for your car.
- We also offer in-store and virtual appointments so you can access our All Things Baby services at a time and place to suit you. Click here to book your appointment. or find your nearest department store here.
All the car seats in our range are designed to give your child the best possible protection and meet the criteria set out in the R129 (iSize) safety regulation. A baby must travel in the safer rear-facing position up to the minimum recommended age of 15 months. Some R129 car seats can be used rear-facing until a child is 105cm tall, which is around 4 years old.
Side impact testing is assessed as part of the regulation to improve the protection of the child’s head and neck. R129 also makes use of the most high-tech crash test dummies which not only has improved sensor technology to test for greater sensitivity, but it also features more sensors on fragile areas of the body. iSize is an enhancement of R129 that makes it easier to confirm your car seat's compatibility with any iSize approved vehicle - reducing the risk of installing your car seat incorrectly. While all i-Size car seats meet the R129 testing standards, not every R129 car seat is an iSize compatible seat.
R129 (iSize) car seats are classified by height only. The below table is a rough guide as to how the car seats can relate to a child’s age based on the average child's height. In some instances, we may still need to check the weight of the child within the height band due to the maximum mass load permitted on a vehicle’s ISOFIX points.
| Type | Height of Child | Approx. Age of Child |
|---|
| Baby | 40-85cm | Birth up to 15 months |
| Toddler | 40-105cm | Birth up to 4 years |
| Toddler | 40-150cm | Birth up to 12 years |
| Toddler | 76-150cm | 15 months up to 12 years |
| Child | 100-150cm | 4 to 12 years |
Note: This is a rough guide only. Please always refer to the individual car seat’s guidance for more specific details. Some car seats will be approved for use across two or more height bands. This just means that these seats have the ability to adapt as your child grows, meaning they can use them for longer.
