Simple, light and easy to install and remove
For the price, it’s great value. Nice and easy to install and very light. Having so many kids seat over the years, premium, expensive variety, I decided on a simple low cost one to make install and removal easy. This is exactly that. No isofix, that’s one downside but if you are looking for simple quick install and removal, isofix does not provide this. Couple of small cup holders on the side also.

Graco car seat
Excellent product. Used while my 6 year old son was over from Australia

Great for 1 metre tall child to 12 years old.
Perfect car seat for my 1metre tall grandson. Lots of seats state age 4 which my grandson is not as being only 3, but this seat is ok from 1m tall. So fed up with struggling with a 5 point harness and this is just wrap and click like an adult seat. It also has the cup ( or hot wheels car) holders on both sides of the seat. The price is also very reasonable as I didn’t want to pay more than forty pounds and this well under that.

Great childs car seat with their own cup holders
The car seat was very easy to put together and it’s very lightweight. It is well padded for safety and comfort which is essential for such a precious passenger. I am really pleased with the car seat and my Grandson is thrilled to have a new seat, especially with cup/bottle holders.

Smart, good value, effective.
Can’t find a fault with this car seat, does the job, looks good, cup holders appreciated by the occupant. I always complain about intructions that are in pictorial form and these were no exception but it’s easy enough to assemble and install.

Handy booster seat for occasional use.
Easily removable booster seat suitable for occasional use with older children, very lightweight, I personally would prefer it if the back was a little more substantial.

Excellent product
This is a great seat at a great price. I bought two to upgrade from baby seats. So much easier to install and remove whilst providing high safety standards.
