ISOFIX Bases – Safer, Faster Car Seat Installation Every Time

Shop our range of ISOFIX bases – the safest and most convenient way to install an infant car seat in your car. An ISOFIX base connects directly to your car's built-in ISOFIX anchor points, eliminating the risk of incorrect seatbelt installation and making every journey safer and quicker. Free UK delivery available. Compatible with all major infant car seat brands.

ISOFIX Base vs Seatbelt Installation – Which Is Safer?

Both methods are safe when used correctly, but ISOFIX bases offer significant practical advantages:

  • ISOFIX base – Connects directly to the car's rigid ISOFIX anchor points with an audible click confirmation. Eliminates the risk of incorrect seatbelt routing. The car seat clicks on and off the base in seconds – ideal for multiple daily transfers. A support leg or top tether provides additional stability. Recommended by most car seat safety experts as the preferred installation method.
  • Seatbelt installation – Works in any car with a seatbelt (including older cars without ISOFIX). Correct installation requires careful routing of the seatbelt and firm tensioning. More prone to installation error, particularly under time pressure.
  • Our verdict – If your car has ISOFIX anchor points (most cars made after 2004 do), an ISOFIX base is strongly recommended. The click-in/click-out convenience alone makes it worth the investment for parents doing multiple daily transfers.

How to Choose the Right ISOFIX Base

  • Car seat compatibility – An ISOFIX base only works with specific car seat models from the same brand. Always check that the base is compatible with your car seat before purchasing.
  • Car compatibility – Check that your car has ISOFIX anchor points and that the base fits your specific car model. Most bases include a car compatibility list.
  • Support leg vs top tether – Most ISOFIX bases use a support leg that rests on the car floor for additional stability. Some use a top tether that attaches to an anchor point in the boot. Check which your car supports.
  • Travel system compatibility – Many ISOFIX bases are compatible with pushchair adapters, allowing the car seat to click directly onto a pushchair frame – a key feature of travel systems.

Frequently asked questions

Helpful answers to some of the questions our customers ask most often.

An ISOFIX base is a separate unit that installs permanently in your car using your car's built-in ISOFIX anchor points. Your infant car seat then clicks onto the base rather than being secured with a seatbelt each time. The main benefits are safety (rigid connection to the car with audible click confirmation, eliminating seatbelt routing errors) and convenience (the car seat clicks on and off in seconds). You don't strictly need one – infant car seats can be installed with a seatbelt – but if your car has ISOFIX points (most cars made after 2004 do), an ISOFIX base is strongly recommended by car seat safety experts.
Most cars manufactured after 2004 have ISOFIX anchor points, and all new cars sold in the EU and UK have been required to include them since 2014. To check: look for the ISOFIX symbol (a circle with 'ISOFIX' written inside) on or near the rear seats, or feel between the seat cushion and backrest for two metal anchor bars. Your car's owner manual will also confirm whether ISOFIX is fitted and which seating positions have anchor points. Before purchasing an ISOFIX base, check the base manufacturer's car compatibility list to confirm it fits your specific car model.
No – an ISOFIX base only works with specific car seat models, typically from the same brand. For example, a Joie ISOFIX base is designed to work with compatible Joie infant car seats, not with car seats from other brands. Always check that the base and car seat are listed as compatible before purchasing. Using a car seat on an incompatible base is unsafe and may not provide the protection the seat is designed to offer. If you're buying a car seat and base together, look for a bundle or confirm compatibility in the product description.
