✅ Seat is good for you if you:

✅ have a high percentile child

The Diono Solana 2 booster is great for your big kid, andone of our favorites for high percentile kids for two main reasons. First, it has high limits of 120 pounds and 63 inches. Many boosters have 57″ limits, even though only about half of the kids who reach 57″ can fit into the adult seat belt properly. This backless booster also has a wider seat pan than many boosters so it can accommodate a larger child without causing them discomfort.

🚩 Use Caution If you:

🚩 need to fit three car seats across in the back seat

This seat is 18.5″ wide, so if you need to fit 3 across in your vehicle, the Diono Solana 2 is probably not the seat for you. If you are looking for narrow options, head here.

⭐️ Stand Out Features:

⭐ lower anchors

The Diono Solana 2 LATCH booster comes with lower anchors to hold it into the vehicle. They are optional, but using them keeps the booster in place when the child is buckling and it keeps it from becoming a projectile in a crash if the child is not riding in it. If you do not use the lower anchors, the child should buckle in the seat belt over the booster whenever they are being dropped off.

⭐ lightweight

At only 6.6 pounds, this is a fairly lightweight option compared to when your child was using a harnessed seat! This makes is easier to carry around to different vehicles when needed.

✈️ Airplane Use

Like all boosters, the Diono Solana 2 does NOT have aircraft approval. But because it is so small, this is still a great option when traveling via airplanes. You can have it under the seat in front of you or stick it in one of your bags, it’s just not suitable for installation on the airplane.

SITS Bottom Line

This is a great, inexpensive booster option for any child who is mature enough to sit properly and is at least 40 pounds. But it’s especially great for even the kids who are high percentile for height and/or weight. The lower anchors are a nice added feature, along with the two, retractable cupholders. If you are looking for a seat to fit in a three across configuration though, this is probably not the booster you want to buy.

What About Seats We Don’t Recommend?

Just like anyone, we have preferences! This goes for car seats, too. If we don’t recommend a car seat, it’s not because it’s unsafe for your little one. All car seats are safe if they’re installed and used properly, are not expired or damaged, and when they’re made and sold by a reputable manufacturer and/or retailer.

A note about crash-tests

How does the Diono Solana 2 LATCH perform in crash tests? 

Well, that’s a great question. We know that it passes the strict federally required testing that applies to all car seats sold in the United States. But we don’t know exactly how it performs. That data isn’t released by any official sources in the US — not by car seat manufacturers, not by government agencies like NHTSA, not anywhere! 

There are a few third-party websites that claim to offer objective crash test data for a variety of car seats. But we at Safe in the Seat don’t pay attention to that data for a few big reasons. First of all, third-party crash tests don’t actually give us meaningful data! Car seat manufacturers crash-test their products hundreds, even upwards of a thousand times. They crash test the finished product in every single installation configuration using every applicable-sized crash test dummy, not to mention a whole lot of testing at each stage of the development process too. So one or two crash tests completed by another organization just can’t give the same level of information! One or two crash tests aren’t going to represent the overall average performance of any car seat across its lifespan. The important thing is to always read the manual before using any car seat or booster.
