Booster Styles and Configurations Compared
Booster style
The Diono Connect3 R is a 2-in-1 high back booster, offering a backrest that adjusts to 11 positions with a dual protective head and backrest design. This provides substantial side support and neck cradling for sleeping children. In contrast, the Diono Solana 2 XL Pack is strictly a backless belt-positioning booster. It lacks a backrest entirely, relying on built-in padded armrests for lateral stability. If you need head support or a reclining seat for naps, the Connect3 R is the only viable option here. The Solana 2 XL is designed for older children who do not require back support.
Seating capacity
A major difference lies in how many seats you get. The Diono Connect3 R is sold as a single unit. You purchase one high back booster for one child. The Diono Solana 2 XL Pack, however, comes as a 2-Pack. This means you receive two backless boosters in one box. If you have two children who are ready for backless boosters, the Solana 2 XL Pack provides two seats immediately. The Connect3 R would require buying a second unit separately. For families needing to seat multiple children at once without buying multiple boxes, the Solana 2 XL Pack offers greater immediate capacity.
Width and fit
Width is critical for fitting three seats across a vehicle bench. The Diono Connect3 R is exceptionally slim, measuring just 16.3 inches wide. This slim profile allows it to fit three-across in many mid-sized sedans and SUVs, a key feature of Diono’s design. The Diono Solana 2 XL is wider, at 18.5 inches. While still compact, it is over two inches wider than the Connect3 R. If your goal is to maximize space in a tight backseat, especially for three-across installations, the Connect3 R has a clear advantage due to its narrower footprint. The Solana 2 XL is wider and may not fit three-across in all vehicles.
Cup holders
Both products include cup holders, but the implementation differs. The Diono Connect3 R features a removable cup holder that can nest between seats for a 3-across fit or store underneath the booster. It is a single, detachable accessory. The Diono Solana 2 XL includes two built-in retractable cup holders that double as snack trays. These are integrated into the seat structure and do not require removal or separate storage. If you prefer integrated, always-available cup holders without managing loose parts, the Solana 2 XL is superior. The Connect3 R’s removable holder offers flexibility but requires more handling.
Height and profile
The physical height of the booster affects how it sits in your vehicle and how much headroom it uses. The Diono Connect3 R stands 23.6 inches tall, providing a high back that extends well up the vehicle seat. This high profile supports the head and neck. The Diono Solana 2 XL is much lower, at only 9.4 inches tall. As a backless booster, it sits low on the vehicle seat cushion. If you need a booster that extends high up for head support, the Connect3 R is the correct choice. The Solana 2 XL is low-profile and suitable only for children who do not need back or head support.

Parents needing three-across fit in mid-size cars
The Diono Connect3 R measures 16.3 inches wide, allowing a slim fit for three-across seating in many mid-sized sedans and SUVs. Its 2-in-1 high back design offers 11 adjustable headrest positions for growing children. The removable cup holder nests between seats when not in use, maximizing rear bench space without sacrificing safety or comfort.
Families buying two boosters for older kids
The Diono Solana 2 XL comes in a 2-Pack, providing two backless boosters for the price of one unit. Each seat features built-in retractable cup holders and a snack tray, keeping drinks and essentials close at hand. The backless design saves space, while dual latch connectors ensure secure installation for children weighing 40 to 120 pounds.
Shoppers wanting high-back support and nap comfort
If your child needs side support or sleeps in the car, the Connect3 R high back booster is the better choice. It includes a SleepyCheek ergonomic headrest angled for neck support and a 2-position reclining backrest. The breathable ventilation helps maintain airflow, while the premium 2TexFoam seat base provides unmatched comfort during longer trips.
