Bubsngrubs are a great place to buy for babies and kids. They had a large choice of colours for this car seat and it was handy to be able to choose one a different colour to the ones our daughters own so we can tell which is ours. Bubsngrubs were very helpful when we contacted them and the car seat was delivered quickly and arrived in perfect condition. I love that they give the option to buy a seat protector and mirror at a discount. Once again, buying from Bubsngrubs has been a very positive experience.

Highly recommend. Had a nuna and the straps were so easy to twist and so hard to untwist. So much easier to put my one year old. Nice and compact too.

Have the non isofix version and loved it so had the opportunity to get the isofix and the installation is even more easier! Love the maxi cosi Pria car seats, they’re just made so well!

Easy to install and very premium feel! My reflux baby seems to like this seat over the capsule! The Isofix makes installation quick. The features make this car seat worth every cent.
