Connect3® RXT 2-in-1 High-Back Booster is the first and only booster with a unique, multi-patented design that enables it to fit 3-across in a variety of combinations with other Connect3® boosters, Radian® convertible car seats, and adult passengers in most mid-sized sedans and up.

The Connect3® RXT 2-in-1 High-Back Booster was submitted to JPMA for the 2024 Innovation Awards. All Connect3® models share the patented 3-across features that won the award in the Child Restraint Systems category.

Features:

  • Fits 3-Across - Our famous slim-fit design now in a booster that’s less than 17" wide and has an innovative seat contour around the EasyPath® lap belt guides for EasyReach™ buckle access.
  • Combined DualProtect™ head and backrest adjusts to 11 different positions, with a fastening carabiner to keep the shoulder belt in place.
  • Premium latch connectors - Built with easy-release straps that are accessible on the front of the booster for seamless grab and go. Plus, a built-in carry handle and can convert to backless mode.
  • Nap-Friendly - The SleepyCheek™ ergonomic headrest has a perfectly angled contour for your child to snooze comfortably with head and neck support.
  • Unmatched Comfort - With a 2-position reclining back rest and premium 2TexFoam seat base, the Connect3® prioritizes safety without compromising on comfort.
  • Innovative Layout - Includes a removable cup holder and separate combined cup/snack tray, which conveniently attaches in the 3-across set-up, allotting a spot for every child to have their designated space.
  • Backseat Snacking - Includes a cup holder and combined cup holder + snack tray, which are removable and can nest between Connect3® seats to accommodate a 3-across fit and store under the booster seat when not in use or on the go.

Will the booster seat fit 3 across in my car?
Connect3® is the first and only booster that can fit 3-across in a variety of combinations with other Connect3 boosters, Radian® convertible car seats, and adult passengers in most mid-sized sedans and up.
When is my child ready for a booster seat?
Diono® booster seats can be used for children weighing 40-120 lbs. (18-54 kg) and are 38-63 in (96.5-160 cm) tall. Typically, once a child reaches five years of age, they are mature enough to ride in a booster seat.
When does my booster seat expire?
All Diono® booster seats have a life span of 8 years, starting from the date you purchase your seat. In the event the date of purchase cannot be determined then we use the date of manufacture.
Can this booster seat be installed if the vehicle headrest is removed?
DO NOT use this child restraint backless unless there is a vehicle headrest for that seating position. For more information, please refer to your booster seat and vehicle owner's manual.
Can I use them on flights?
Diono® booster seats cannot be used on airplane. Boosters require both a lap and shoulder belt, and airplanes only have a lap belt.
Can I use this product if I don’t have a LATCH system?
Yes, your booster seat can be used without the LATCH. ALWAYS secure the child restraint using the vehicle seat belt or LATCH even when it is unoccupied. It could injure other occupants in a sudden stop or collision.
How do you install this product using the LATCH?
Lay booster sideways, press silver lever, and pull LATCH connectors. Don't overextend. Attach both connectors to the car anchors, farthest first. Ensure hooks face up. Pull both straps while pressing booster into seat. Ensure connectors are secured.
How do you uninstall this product's LATCH system?
Disengage lower anchors by reaching on the side of the booster seat and depressing both cam locks while pulling the seat away from the vehicle seat until the straps are extended fully. Unhook lower anchor connectors from the vehicle LATCH anchors.
