Review: Great value for money - Excellent car seat. Very easy to use and put in and out of the car. My daughter can also get herself in and out quite easily and she says it is really comfortable with the padding. Feels sturdy and secure but is still lightweight and easy to carry if changing between cars etc. Great value for money as it should last until she does not need a car seat any more.
Review: Brilliant purchase - looking for the right car seat is an absolute pain in the backside. To know what is right, safe and quality for your children is a huge worry and we ended up opting for the tried and tested Maxi-Cosi Kore i-Size. The seat is brilliant, the Isofix has a tight ratchet which allows the car seat to hug the seat and not move. The seatbelt doesn't catch and is easy for our 4-year-old's to put on and take off. I highly recommend these seats as a dad of 5 (we bought 3). They are sturdy, well built and comfortable and most importantly safe. All though they do have a hefty price tag (when compared to the budget seats) they still represent excellent value as the children will probably use then for 3 - 5 years, An absolute safe bet if you are unsure - you will be very happy with the seats for your precious children.

## Questions & Answers

**Q: Does this leave car seat marks/indents on leather after prolonge use?**
A: Well, the seat weight itself is hovering around 3kg, so not very much.
But sure, it'll leave marks on leather after prolonged use.

**Q: Is the backrest meant to move?

When installed correctly in my car, the back rest seems to be able to tilt forward slightly. Is this normal?**
A: Mine does this also. I think the back of the seat is hinged slightly so it fits different back seats as they are all angled differently. Once the child is in with the seatbelt on nothing is going to move.

**Q: Does it recline?**
A: I wouldn’t say it reclines but the back can move to fit the angle of the seat it’s going on. It’s a bit hard to explain but yes the back tilts slightly.

**Q: Is this the Kore Pro?**
A: This is the simple Kore.
Kore pro has snazzy side lights to help buckle seatbelt in.

### ⭐⭐⭐⭐⭐ Love this seat. So glad we paid a bit extra for the quality
*by B***A on 28 March 2020*

So after my son grew out of his original maxi cosy isofix seat, we needed something a bit bigger that utilised the cars seat belts. There are so many available, with and without isofix. We wanted isofix, so the chair wouldn't move about when not in use. There are so many cheap chairs and really expensive chairs, we really didn't know wether the money made any difference. So after a visit to a shop to look at some properly, we came acros this one. It's really sturdy and comfortable. It fits my son perfectly. We ordered from Amazon as it was cheaper than the shop. It arrived promptly and we put it in our Audi q2. It fits perfectly, and my son loves it. He is able to do his own seat belt due to the design (which he can't in our second seat) so that makes things much easier. So I would say but this one, not a cheap one, it's so worth it
