The Diono Connect3 RXT is a 2-in-1 high back booster designed to serve children from 40 to 120 pounds, transitioning from a harnessed booster to a belt-positioning booster as the child grows. Its slim fit profile allows three-across installation in many mid-sized sedans and SUVs, making it a practical choice for families with multiple children or limited backseat space. The seat features a lightweight construction with an integrated Latch system for secure and straightforward installation in most vehicles. Safety is addressed through the reinforced steel frame and energy-absorbing foam layers that work together to manage impact forces.

The adjustable headrest and harness system accommodate growing children without compromising protection. The side impact protection pods extend outward to shield the child in the event of a collision, while the deep side wings provide additional containment. The buckle and harness adjusters are designed to be user-friendly, enabling quick tightening and loosening without pinching fingers. Comfort is supported by multiple recline positions and a padded seat cushion that remains supportive during longer rides.

The fabric covering is breathable and machine washable, simplifying maintenance after spills or daily use. The cup holder is removable and dishwasher safe, adding convenience for parents. The booster mode uses the vehicle’s seat belt and guides the belt correctly across the child’s shoulder and lap. Construction emphasizes durability with a solid plastic shell and aluminum-reinforced sides.

The lightweight design (under 10 pounds in booster mode) makes it manageable for transferring between vehicles or storing when not in use. The Latch connectors are sturdy and clearly color-coded for correct attachment. The entire seat meets or exceeds federal safety standards without relying on proprietary locking clips.

At a price point of $159.00, the Diono Connect3 RXT offers a combination of slim footprint, extended weight capacity, and safety features that suit families seeking a long-lasting seating solution. The Purple Wildberry color adds a vibrant option that appeals to children while remaining easy to clean. The seat works well in compact cars, minivans, and larger SUVs, providing flexibility without sacrificing protection.
