These seats are designed to adapt and grow with your child, which eliminates the need for multiple car seats as they get bigger, saving you money in the long run! 

Today’s all-in-one convertible car seats are all about form and function, but none more so than the Radian 3 RXT Safe+ All-In-One Convertible Seat from Diono! 

With a reputation as one of the safest seats around, the Safe+ is an upgraded version of Diono’s 3 RXT model. What’s more, it’s received glowing reviews from both industry insiders and parents alike! 

So come with us as we explore why this car seat is such a standout and whether or not it will be the only car seat your little one will ever need.

Installing the Safe+ is a hassle-free experience. Whether you opt for the LATCH connectors or your vehicle's seatbelt, the seat's adaptable nature caters to your preference. Additionally, it's designed for installation in both rear-facing mode (perfect for infants and toddlers) and forward-facing mode (for kiddos who max out of the weight or height limit in rear-facing mode).

Moreover, its slim-fit construction, with a width of just 17 inches, guarantees a perfect fit even in a three-across configuration. This feature maintains safety standards, ensures ample space in the vehicle, and prioritizes the comfort of your child throughout the journey, in any mode.

The Safest of All 

The Safe+ is a fortress of safety features, ensuring top-tier protection for your little one on every ride. Here's a breakdown of the safety components Diono packs into this seat: 

  1. Rear-Facing Engineering:
    In the event of a collision, an included steel anti-rebound bar decreases rebound rotation by up to 50%, ensuring maximum safety. 

  2. Steel Reinforced Frame and Shell:
    Mechanically engineered from reinforced automotive-grade high-strength steel, the seat's unique core shell provides an added layer of protection and security for your child. 

  3. Rollover and Side-Impact Testing:
    The seat is rigorously tested for rollovers and side impacts, ensuring it meets and exceeds safety standards.

  4. Six Layers of Side Impact Protection:
    Extended sidewalls and six layers of SIP provide an additional cushion of safety for your child.

  5. Enhanced Headrest and Support:
    The improved headrest, designed with high-performance foam padding, offers 12 head support positions, boasting a 22% range increase over their 3 RXT model!

  6. Newborn Assistance:
    The seat includes a two-in-one infant liner and a newborn travel high wedge, which cater to the specific positioning of newborns.

  7. Five-Point Harness with Anti-Slip Pads:
    A comfy five-point harness is equipped with anti-slip pads, ensuring your baby stays in the correct position and maintains optimum safety levels while in the seat!

Thoughtful Convenience  

The Safe+ doesn't just excel in safety. It also champions convenience with an array of thoughtful features! 

Available in five modern, sleek looks, this seat perfectly caters to your personal style. The premium fabrics adorning the seat not only offer ideal comfort but are also machine-washable (although it's worth noting that some reviews mention challenges in removing and reinstalling the cover after cleaning).  

Adding to its user-friendly design, the seat boasts a steel-reinforced XL cup holder, ensuring your little one's drinks or snacks are within easy reach while on the road. Speaking of which, the Safe+ also has the unique ability to fold for travel (or compact storage) — it’s actually the original and only (as of this writing) all-in-one convertible car seat with this feature! Further emphasizing its portability, the Safe+ is FAA-approved for airline use which makes it a top travel option for families on the go.
