Does the 80 lb lower anchor limit apply to all LATCH equipped vehicles?

Seats made prior to March 2014, the 80 lb lower anchor limit for U.S. RadianRXT and RadianR120 (and 65 lb limit for RadianR100) is only for vehicles manufactured after September 1, 2005 when vehicle lower anchor strength requirements were increased. All Diono car seats manufactured starting March 2014, check labels and manual for child weight limits with lower anchor installation.

Do all of Diono car seats have side impact protection?

Yes, all Diono car seats provide reinforced side-impact protection, and some models offer the increased protection of an adjustable head support. Currently, there is no U.S. or European regulatory side-impact testing requirement. A manufacturer can make the claim of “side-impact safety” without meeting any standard. Diono’s RadianRXT and Monterey models were side-impact tested to the widely accepted German standard established by ADAC, Europe’s largest automobile club.

Do all car seats sold in the U.S. actually meet the National Highway Safety Administration’s FMVSS213 standards?

FMVSS213 does not require child seats to achieve performance results with RF children above 22 lbs and for FF children above 50 lbs. Radian and Monterey meet all the performance standards with all weight children, RF and FF. Radian does this with and without using top tether.

Why crash test with no top tether?

While we always recommend top tether use, car seat safety should not depend on it:

  • Many seating locations or vehicles do not have top tether anchor points.
  • Most vehicles do not allow top tether use with children above 48 lbs.
  • Studies show that less than 30% of car seats are installed with top tether.

 Can I order replacement SuperLATCH parts for a Radian seat and use it up to the higher LATCH capacities?

Replacement SuperLATCH components can be ordered, but Radian seats can only be used up to the LATCH/UAS capacity stated on the stickers that are affixed to the seat.

Are Radian seats FAA certified for use on an airplane?

Yes, all Diono child car seats (with integral harness) are certified for use on aircraft.
