Excellent Product

Excellent car seat, slender but with somehow more space for comfort of your child. Their is so much more room in the car, no bulky cup holders, no extra bits to clean.

Checks all my boxes!

Really good seat. My daughter tends to sleep on long drives and this allows her the comfort to do that. Checks all my boxes on safety, comfort and ease of assembly. I'm certain she'll have this till she transitions out of car seats

Seller Verified Purchase

Easy install. Forward facing. Fits 3 across.

Would highly recommend. Easy to install and the straps tighten so easily. I've owned Graco, Evenflo and Britax and would choose Dione all day long for forward facing. Perfect to seat 3 across in our 2022 Hyundai Santa Fe. Have only tried forward facing so cannot comment on rear facing.
