Nuna Mixx base compatibility with other brands

[Rightwriter]

We have the Nina Mixx travel system, but will soon need to upgrade to a toddler car seat. I wondered if any other brands, eg Joie, Maxi Cosi, etc, are compatible with the Nuna base?

No they aren't. The only seat you can put onto that base is the Nuna Todl Next.

But there are a lot of seats which cost less than that seat (£330) which don't need a base, and that's what I'd look at personally, so you can keep your base in case you have another baby.

For example these are the seats I'd look at:

Rotating seats with their own isofix base built in, very similar to or better than the Todl in terms of quality and features, first three around the £300 mark

Britax Dualfix Pro
Cybex Sirona Gi i-size (20kg weight limit)
Maxi Cosi Mica Pro Eco
Axkid Spinkid 2 (better leg room)

Britax Dualfix Plus - this one is also currently reduced to about £200/220 and I would say it's comparable to the Todl, or better as it has a higher weight limit (20kg whereas Todl is 18kg).

Joie i-Pivot 360 - same parent company as Nuna, higher weight limit (21kg) and currently under £200, however I would say that Joie is a more budget-friendly brand than Nuna, and the fabrics and user-friendliness of the inserts and straps reflect this. The safety is just as good.

Besafe izi Turn or Twist i-size - This one is very slightly more expensive than Nuna Todl, but worth mentioning because it's MUCH better if you have very sloping seats with the isofix point lower than the edge of the back seat in your car. That kind of configuration can cause the seat to be too tipped backwards which can push babies' heads forward when they move into the next seat. The Besafe seat has a different design to counteract this.

Non-rotating seats worth a look:

Or you could look at Swedish plus tested seats, supposedly the toughest crash test in the world, which will allow you to rear face roughly twice as long as a spin seat, and provide much better leg room for children as they grow. Again, these don't need a base. Most don't fit using isofix, but the car's seatbelt. Because they are bigger seats they stay in place so this isn't really an issue. I'll list the seats under £330 and then one which is over just in case.

Axkid Movekid
Avionaut Sky
Britax Max Safe Pro
Britax Safe Way M

Axkid One2 - the only isofix one - this is roughly £500 but as said, it will last around twice as long as the spin type seats.

This is really helpful, thanks so much!

I hadn’t heard of Swedish crash tested, so will take a look - all for finding a great robust seat.

Appreciate your wisdom, thanks again!

This is some info about the Swedish plus test (an article and a video).

There are some rotating seats (180 degree rotation) which are plus tested (britax swingfix, axkid spinkid, besafe izi twist) but the non rotating ones last longer, up to 125cm rather than 105cm.

You don't necessarily have to go for a plus tested seat to get the benefits of rear facing but it is worth knowing about IMO. It can be good to see the different seats in pers
on so it may be worth looking in the Axkid website at their stockist search to see whether there's a specialist retailer near you. They will often stock both plus tested and full 360 degree seats so you can compare the different options.
