  1. Lynette

    We have a number of Britax car seats and find them superior in protection and comfort for our grandchildren (4). Helps that the kids like to sit in them also. Yes they are bulky, heavy, but we are prepared to tolerate this to ensure the kids (age 18mths to 5yrs) are safe at all times.
    They are so easy to install in and out of the various vehicles (cars, utes,hot rods) that we own, that in itself is a big plus. Simply use existing car seat belt, thread through (and this is no hard chore) and buckle up. Even Poppa can get it sorted fast.
    They are not cheap, I take advantage of the Oxipay payment plan, this enables us to have these superior products of Britax for my grandchildren.

    We recently purchased the ONE4LIFE CLICKTIGHT carseat for our 7 week old who was fast growing out of his capsule. It is so easy to install and looks great, baby loves it and falls asleep straight away. We are very happy with it and knowing our child is safe, comfortable and he is going to be tall we were looking for a seat that we wouldn’t have to replace every 2 ish years – definitely found it. It also allows more room for the front passengers seat to recline than the capsule that we had. The team at Albany were super helpful!

  3. Grace

    Love the car seat, so easy to install.

    BUT it bobbles & have noticed that the material has bobbled on the side & frayed where the legs rest.
    Which is so dumb as it makes it look old & rough.

    Thanks, Grace

    Easy to install and switch between cars which is great. Our 3 year old son loves the cup holders for his water bottle and snacks. It is great that there is a place for the instruction book to be kept so that it can stay with the seat and not be lost. Really pleased to have found a seat that can be used for many years as we have previously spent a small fortune on others that our son has outgrown.

  5. Michelle

    I bought a britax boulevard click tight 2 years ago, it has been such an awesome seat, hassle free installation and comfy, my toddler sleeps comfortably in it. Will be upgrading our second seat with the britax all 4 one for my main car and using the boulevard as the second seat.
