The ISOFIX base makes installing your protect or alpha capsule ultra safe and easy. Install the ISOFIX base using ISOFIX anchor points in your car, then click protect or alpha in and out for a safe and convenient fit, every time.


  • designed to make the fitting of child seats into cars quick, simple and above all safe
  • compact and flat with a slim fit
  • ISOFIX connectors attach to any car with ISOFIX anchor points
  • a sure fit every time, ISOFIX minimises the risk of not installing the capsule correctly into the car
  • correct-fit indicators for 100% confidence in your installation

*Note, in some cases ISOFIX installation won't work in a vehicle due to the angle of the base if the seat bolsters are high at the front, in certain cases it may be better to use the universal base.

Awesome seat

Really like this seat for my son. And he loves it too. Easy to install and leaves a good amount of leg space for the front passenger. The drop down tether makes it easy to get him out and put him in.
Winkalotts service was also fantastic. Ordered at 12pm one day and was delivered at 9am the next day.

Awesome booster seat

Kids love them, perfect for growing kids once they are too big for their car seats. Comfortable. Purchased an extra seat to go in the grandparents car as well as good value for money safe booster seat. Love the isofix locking booster into back seat, sturdy.

Awesome seat

Awesome seat, easy to install and fits really securely in the car

No brainer

We already had one hi liner, so knew they were a fantastic seat for our 5 year old.
Winkalotts provide super quick delivery and we’re the cheapest around.
Our 5 year old loves her seat and we love knowing she is safe!
Great seat, great price, great service

1st Birthday gift

Package arrived in time stated.
Has not been opened yet as 1 more week till grandsons birthday

Ordered from Scotland so that I was sure it would arrive for his 1st Birthday.

Have not seen my grandson yet due to covid and cancellation of plans when he was born.

Desperate to hold him and also desperate to hold his parents tight in a hug.
