Battle of the beasts

In June 2014 Diono NZ announced changes to the seat range being sold here.

Previously we sold the Diono RXT and R100. While you can still get the RXT model, in limited colours, you can only get them at Baby On the Move stores around the country. All other retailers now sell the new models, the Diono Rainier, which is a step up from the RXT, and the Olympia which replaces the R100.

The seat stats are as follows:


  • Rear facing to 20 kg
  • Forward facing to 36 kg
  • Booster to 54 kg


  • Rear facing to 18 kg
  • Forward facing to 29 kg
  • Booster to 45 kg


  • Comfortably seats rear-facing children from 2.3 to 22.7 kg
  • Highest forward-facing capacity of any convertible car seat in a 5-point harness: from 9.1 to 40.9 kg (up to 144 cm in height)
  •  Converts to booster mode for children between 22.7 and 54.5 kg. (up to 144 cm in height)


  • Comfortably seats rear-facing children from 2.3 to 20.5 kg
  •  Forward-facing capacity in a 5-point harness: from 9.1 to 31.8 kg (up to 144cm in height)
  • Converts to booster mode for children between 22.7 and 50 kg. (up to 144 cm in height)

Height limits remain unchanged. But what has changed are discussed below:

Higher weight limits on the newer models
New fabric with different colour schemes
Wider seat shell wings, the bulk of the shells remain the same, the side wings have had a piece added. This enhances side impact protection, and allows more shoulder room for older children.
Additional shoulder straps for use with children over 29 kg in weight who are still using the harness straps.
New seat name/s.

The issue you may find with the difference in size is that the new models are less likely to work in a 3-across set up. They do still fit well in most cars where this is not required.

Here is an image of the size comparison:

Car seat conscious mother pleased

The following information and photos are from a mother in our online car seat community who faced an impact in a high speed zone recently, her story below. Thanks Tanya L.

“Crash was in 100km zone when a Land-cruiser was pulled off to the side of the road and did a u turn in front of me. I can’t be certain of speed at time of impact as I did get a chance to brake and swerve to try and avoid him.
Initial impact was my front/passenger side to his front drivers side but it must have spun me round a bit to damage the whole passenger side from bumper to bumper. Passenger front door was unable to be opened, wheel pushed right back into back of front guard.

Mr 3 in Nov was passenger back forward facing in xtsl
Mr 6m middle rear facing safety 1st compete air 65se
Mr 7 in Nov drivers side rear in Nania befix booster.

Normally it’s baby in on board air capsule passenger rear, middle boy in the middle rear facing in complete air and big boy forward facing in radian on drivers side but I’d left the capsule in hubbies car and had to do a quick swap around for the school run, of course that would be when someone tries to take us out!”

We’d like to take a moment to remind you that lives are precious, we know you love your kids, so always take the time to correctly install your seats regardless of the weather or if it’s ‘just a quick trip’. Where you’re uncertain, or want to be sure you have it right, have a technician check it. Always use a car seat or booster on every ride, no matter the duration or the type of roading.
