Joie Bold Highback Booster Car Seat with Harness - Slate is rated 4.1 out of 5 by 58.
Rated 5 out of 5 by from All over a great seat Bought the seat just over a month ago. Super comfy for my little boy. So easy to fit as long as your car has all 3 fitments. Love the fact the harness is up to 25kg instead of 18kg too

Rated 5 out of 5 by from Really pleased with this seat! I had a bad experience with the Joie 360 so I was a bit reluctant to try Joie again but as my 2.5yr old is nearing 18kg I needed an extended harness seat and this one goes up to 25kg and other market options were quite limited. I really like this seat and so does my little boy, it took a bit of getting used to as I was used to my GB Vaya spinning seat but once I’d got the hang of it it’s fine. I like tthat it’s soft and padded well. the little cup holder is a great feature for my little boy too. I also like the adjustable headrest and no re-threading of straps!! I found it easy to fit, I thought it would be a nightmare installing it with the belt, isofix AND top tether but it was easier than others I’ve fitted! I think the price is great for a good quality seat that will last us a long time. My boy is very comfy in this seat!

Rated 5 out of 5 by from Fab seat. Love everything. Even slackening the straps is so easy. Push a button and pull left strap. Amazing. Maybe the people who have had problems are not doing it right like me on first try lol. Definitely recommend.

Rated 5 out of 5 by from Perfect fit! Brought this car seat just before Christmas and it’s perfect for us. I got advice in store to make sure it would fit in my car and then they fitted it for me when I collected it. My daughter loves the seat and will happily climb in and wait for me to do the straps up. She loves it even more as she can see out of the window properly now. Overall a perfect car seat!

Rated 5 out of 5 by from Great seat and simple to fit Bought this as my son was too heavy for his old seat. At just under 3 I still wanted the 5 point harnesses so this was about my only option but we love it. Easy recline for when he falls asleep and he loves it, thinks he's a big boy like his big brother. Wish I had got this from his baby carrier

Rated 5 out of 5 by from Excellent Car Seat This is the second one I have bought - for my second grandchild. They are excellent value, superb quality and very sturdy. They stay in place, don't wobble about and the babies/toddlers are very comfortable in them. They love the cupholder. The adjustable headrest and straps make this car seat so versatile to use no matter how large or small the child is.

Is this rear facing and forward facing or just forward facing? My little boy is 13kg and I was looking for rear facing for at least another year if possible? Also is the FX the new name for the Joie bold as I keep seeing different names???

Asked by: Abigail
Hello, Thank you for your query. This car seat accommodates little ones from 9kg all the way up to an extended 25kg using the 5-point harness, and converts to a belted booster from 15-36kg. This is a forward facing car seat. The stages FX offer rearward and forward facing options, and can be used from birth - 25kg. Hope this information is of use.
