Diono Radian 5 (2019) Car Seat

The Diono Radian 5 (2019) is the new version of the Radian that has been sold in the UK for the last couple of years. This features much improved fabrics over the original version both in looks as well as feel. This seat contains several unique features only found on this seat in the UK. The seat is one of a few seats that is tested from Birth upto 25kg with a full 5 point harness. (To be honest we at Paul Stride think it is more suited from 6-9 months upwards rather than from Birth). The basis of the seat comes from its steel frame and energy absorbing EPP foam padding. The combination of these materials means that the seat can be narrower and lighter than the opposition yet still has the strength to endure high impact testing with a child forward or rearfacing to 25kg. For use forward facing upto 25kg the seat must be installed using the top tether anchorage point found in most modern cars. Without the top tether kit this seat cannot be used forward facing.

Due to the large weight and size range of the child in the seat it comes with several removable items to adapt it to your child. Whilst this does mean several items need changing on the seat at different times in practice this wont be that often.

  • Forward facing with 5 point harness upto 25kg (with top tether)
  • Full steel alloy frame for strength
  • Diono V3 Energy Reduction System
  • Super Grip harness pads when forward facing
  • Soft padded harness pads when rearfacing
  • Extra tall backrest for taller children
  • Narrow external width means 3 seats can be installed in some cars
  • All round EPP foam for greater energy absorbion
  • Engineered plastic shell over steel components for strength and durability
  • Expandable sides and movable headrest to grow with your child
  • Fold flat when not in use
  • Soft fabric covers
  • Memory foam seat padding
  • 5 shoulder harness positions
  • 1 cup holder included (others available at extra cost)
  • Top tether required for use forward facing
  • Rearfacing without the use of a foot prop. No problem with underfloor storage compartments.
