Review: Fits in the Scion XB - We have a 2007 scion XB & we tried the diono seats in hopes of holding off buying a brand new car before our 3rd baby arrived. We were able to install 2 diono’s along with our chicco keyfit carseat perfectly in the back seat! Our 4 yr old, 2 yr old (both forward facing) and our new baby will fit perfectly and comfortably in the scion. However, they only fit nicely in forward facing mode because when they are rear facing, the headrest is really tall & the recline is pretty steep, so it definitely would’ve been touching the back seat of the driver or passenger. You can feel the heaviness and durability in these seats compared to the evenflo & graco seats we had, but that’s what also helps me feel secure knowing the kids are safe. My husband is happy that we get to keep the scion for a little while longer! Team no minivan! Review: Best car seat out there! - Our favorite car seat / booster or all time! Worth the price!! Fits 3 across, easy for toddler to buckle themselves and goes in the third row of the car!

Or will it fit in the middle without hitting the driver's seat? Mazda3.** A: Place it behind the passenger side, if you’re shorter. It you’re 6’ tall, it will be too crowded. You may try it in the middle, but it may still affect the front passengers. **Q: How deep does the vehicle seat have to be for rear facing and for forward facing?** A: This seat is hard to install properly while rear facing because of its height. The angle of the seat has a lot to do with it. We have a rav4 and a Prius the Prius actually fit better because of the streeper seating angle. They sell a foam angle adjuster that does pretty well in the rav4, but if I was much taller (I'm 5'9") it'd be a tight squeeze up front (the car seat is not supposed to touch the seat in front of it.) These are very well made though and much higher quality than many other seats in the same price range. Plus you can fit 3 across in every vehicle. I'd recommend to anyone. **Q: Fecha de vencimiento?** A: We ship using UPS ground and normally the item goes out either same day or next day. **Q: How do I secure on in the middle seat in the back (3 seats across ans forward facing) if I don’t have latch in the middle seat?** A: If you are unable to attach the seat with the latch system you can secure it with the vehicles seatbelt. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fits in the Scion XB *by M***N on June 2, 2026* We have a 2007 scion XB & we tried the diono seats in hopes of holding off buying a brand new car before our 3rd baby arrived. We were able to install 2 diono’s along with our chicco keyfit carseat perfectly in the back seat! Our 4 yr old, 2 yr old (both forward facing) and our new baby will fit perfectly and comfortably in the scion.

Team no minivan! ### ⭐⭐⭐⭐⭐ Best car seat out there! *by R***G on June 29, 2026* Our favorite car seat / booster or all time! Worth the price!! Fits 3 across, easy for toddler to buckle themselves and goes in the third row of the car! Also it’s good for 10 years which is much longer than most car seats! ### ⭐⭐⭐⭐⭐ Bought 2 & would buy more *by R***A on December 30, 2025* Super sleek, safe & sturdy. It’s so easy to strap the kids in & adjust knowing they’re safe & secure. I love the strap pads that would 💯 prevent any necks getting slit in an accident. It’s easy to take in & out but it’s definitely not recommended as a grab & go car seat. It’s solid.. the steele frame makes it pretty heavy so as long as you aren’t puny, you’ll be fine. You might break a sweat, transporting it and putting it in another car, but would you rather than be safe or in a cheap inexpensive Walmart car seat with straps that constantly twist. Super comfortable, apparently. My son usually falls asleep before we even get out of town. I bought one for my mom’s car and my husbands mom’s car. We have a different Dion model in ours but this one is easier to use honestly.. ## Frequently Bought Together - Diono Radian 3R, 3-in-1 Convertible Car Seat, Rear Facing & Forward Facing, 10 Years 1 Car Seat, Slim Fit 3 Across, Jet Black - Diono XL Car Seat Cup Holders for Radian and Everett Car Seats, Pack of 2 Cup Holders, Black - Diono Ultra Mat Complete Back Seat Upholstery Protection from Child Car Seats and Pets, Crash Tested, Premium Ultra Thick Padding, Durable, Water Resistant, Anti-Slip, 3 Mesh Storage Pockets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/182696469-diono-radian-3r-3-in-1-convertible-car-seat-rear](https://www.desertcart.tn/products/182696469-diono-radian-3r-3-in-1-convertible-car-seat-rear) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-31*
