Frequently Asked Questions

How long can my child use the Maxi-Cosi Kani?

The Kani is designed to serve your child from birth through approximately 10 years of age, spanning four distinct modes. It starts as a rear-facing seat for infants and transitions all the way to a backless booster for children up to 45 kg (100 lbs).

Can the Kani fit three-across in my vehicle?

Yes. The Kani features an ultra-slim profile specifically engineered to allow three car seats across the back seat of most vehicles. Actual fit may vary depending on your vehicle's interior dimensions.

How do I convert the Kani to backless booster mode?

An intuitive one-hand release mechanism lets you detach the seat back in seconds, instantly converting the Kani into a lightweight backless booster without tools or complicated steps.

Just what we needed
Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack)
This toy has been great for my dog who eats all her toys! We were having such an issue with all of her toys being so hard that we didn’t want to throw them around our house. This was the perfect solution. She hadn’t eaten through it and it’s nice and soft for fetch without destroying your house!

My lab loves t
Color: Orange & Blue Fumbler, Size: 3 x 8.5 x 9 inches (1 Pack)
This toy is my labs favorite toy. She’s obsessed and we were happy to find a toy she loves that can stay inside with us. The problem is how easily she tears it apart. We have to buy her a new one every month because when she bites into it it breaks down the foam inside, and from there she shreds the roping it’s covered in. We try to stop her, but with how often we play with it it’s inevitable. We have resigned ourselves to buying a new one once a month.

Worth the purchase
Color: Orange & Blue Fumbler, Size: 3 x 8.5 x 9 inches (1 Pack)
Perfect for indoor use. My aggressive chewer loves this and has not destroyed it yet after 6 months. I recommend for indoor use as it causes NO damage or noise.

Not Chuck-It Durable
Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack), Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack)
Sadly only lasted an hour. My dog likes to pull apart toys over the course of a few months, with the exception of Chuck-It toys. They usually never get destroyed by him. I think its a good product but if you are looking for the durability like other toys from Chuck It - just wanted to share this is not the toy for you! Made him happy so not regretful of buying it, just wish it lasted longer. Here is him posing with it after he took bites of it like it was an apple.
