What is the difference between this compared to the Frontier Click Tight?

Hi Shelley, Thank you for your enquiry. There are a few main differences between these products. To assist you with a comparison on this or any of our products, we would recommend using our online product comparison tool. Once you have found the product online you are wanting to compare (e.g the Britax Pioneer Booster), select the ADD TO COMPARE option (located by the product image). Continue this process again for each product you are wishing to compare this with and these will give you the product info and dimensions for ech to view against one another. If you follow the link https://www.babyonthemove.co.nz/store-locations/ this will take you to our online store finder. Here you can find contact details for your nearest Baby On The Move Store where one of our expert Car Restraint Technicians can assist in helping you find the right restraint for you, your child and your vehicle.
