These are general buying and feature comparisons, not installation or safety instructions. Always install and use any booster seat exactly as described in the manufacturer’s manual and your vehicle’s owner’s manual. Also check NHTSA’s guidance or consult a certified Child Passenger Safety Technician for an installation check specific to your car and child.
For most families buying a first belt-positioning booster seat, the Diono Solana 2 is the strongest value. At $54.99, it covers a 40-to-120-pound weight range, which works out to about $0.69 per pound of weight capacity — the lowest of the three boosters compared here. Its backless-only shell weighs just 6.1 pounds, so it’s easy to move between two cars. The Chicco KidFit ClearTex Plus 2-in-1 costs nearly double at $109.99, but it’s the only one of the three with GREENGUARD Gold low-chemical-emissions certification. It also has a highback mode with a 10-position headrest for kids who still need extra head support. The Graco TurboBooster 2.0 Highback lands in the middle at $69.99. It’s the pick if you want a simple, no-LATCH highback booster without paying Chicco’s premium.
At a Glance: Our Picks
- Best overall value: Diono Solana 2 — widest weight range (40-120 lbs), lowest cost per pound, $54.99.
- Best for extra head support: Graco TurboBooster 2.0 Highback — hideaway cup holders, machine-washable pad, $69.99.
- Best for tricky installs: Chicco KidFit ClearTex Plus 2-in-1 — built-in LATCH, SuperCinch tightener, GREENGUARD Gold, $109.99.
What Each Booster Seat Costs Per Pound of Capacity
Sticker price alone doesn’t say how much booster you’re actually getting. So we divided each seat’s price by the full span of its published weight range. That span is the highest weight limit minus the 40-pound minimum every booster here shares. The result is a cost-per-pound figure none of the three brands publishes themselves. For Chicco, we used the wider backless-mode weight limit of 110 pounds, since that’s the range the seat covers across its full life.
| Booster | Price | Weight Range | Range Span | Cost per Pound of Capacity |
|---|---|---|---|---|
| Graco TurboBooster 2.0 Highback | $69.99 | 40–100 lbs | 60 lbs | $1.17 |
| Chicco KidFit ClearTex Plus 2-in-1 | $109.99 | 40–110 lbs (backless mode) | 70 lbs | $1.57 |
| Diono Solana 2 | $54.99 | 40–120 lbs | 80 lbs | $0.69 |
The Diono comes out well ahead on this math. That tracks with it being a simpler, backless-only design without a highback shell, LATCH-tightening hardware, or a chemical-emissions certification to pay for. The Chicco’s higher cost per pound reflects everything it adds on top of raw weight capacity — highback support, LATCH, and GREENGUARD Gold. It isn’t a worse value on capacity alone.
What Is a Belt-Positioning Booster Seat?
A belt-positioning booster seat is a raised seat that lifts a child up. It positions the vehicle’s own lap-and-shoulder seatbelt across their body in the right places instead of the wrong ones. Per NHTSA, a properly positioned belt “must lie snugly across the upper thighs, not the stomach.” The shoulder belt should also sit “snugly across the shoulder and chest and not cross the neck or face.” Without a booster, most kids under roughly 4’9″ haven’t grown enough for an adult seatbelt to land in those spots on its own. That’s why NHTSA recommends booster seats for children roughly ages 4 to 7.
All three boosters compared here do this the same basic way: they raise the child’s hips. In highback mode, they also guide the shoulder belt across the chest with a lower belt loop or clip. Where they differ is price, weight range, and certifications. They also differ in whether they anchor to the car with LATCH connectors or rely on the vehicle’s own seatbelt to hold them in place when unoccupied.
When Should a Child Move From Highback to Backless?
A child is generally ready for a backless booster once they can sit still through a full car ride without slouching or pulling the shoulder belt behind their back. They also need a vehicle seat with a headrest tall enough to support their head on its own. Highback boosters add head and side support that backless models skip. That’s why child-passenger-safety guidance from booster makers like Chicco recommends staying in highback mode. This applies if your car lacks headrests at that seating position, or if your child tends to fall asleep on drives.
Of the three boosters here, the Chicco KidFit ClearTex Plus 2-in-1 and the Graco TurboBooster 2.0 both start in highback mode. The Chicco converts to backless later, and the Graco does the same as a 2-in-1. The Diono Solana 2 skips highback mode entirely and is sold as a backless-only booster. That’s why its own product listing doesn’t publish a minimum height the way a highback model does. It’s built for a child who has already outgrown the highback stage, or whose vehicle seat already provides that support.
Meet the Three Boosters
Graco TurboBooster 2.0 Highback
The Graco TurboBooster 2.0 Highback is a 2-in-1 highback-to-backless booster listed at $69.99 on gracobaby.com. It fits children 40 to 100 pounds and 43 to 57 inches tall, starting at age 4. It has hideaway cup holders built into the armrests, a machine-washable seat pad, a height-adjustable headrest and armrests, and EPS energy-absorbing foam in the shell. This particular model does not include LATCH connectors, so it relies on the vehicle’s own seatbelt to hold it in place when a child isn’t sitting in it. That’s a real trade-off against the LATCH-equipped Chicco and Diono. LATCH on a booster is a convenience feature for keeping it from sliding around when empty, though, not a crash-safety requirement the way it is on a car seat.
Buy it if: you want a simple highback booster with washable fabric and don’t mind skipping LATCH.
Skip it if: you specifically want built-in LATCH anchors or a certified low-chemical-emissions rating.
Chicco KidFit ClearTex Plus 2-in-1
The Chicco KidFit ClearTex Plus 2-in-1 is listed at $109.99 on chiccousa.com. In highback mode it fits 40 to 100 pounds and 44 to 57 inches. Once converted to backless mode, Chicco raises the weight limit to 110 pounds. It’s the only one of the three with built-in LATCH connectors and a SuperCinch one-pull tightener for installation. It also has a 10-position adjustable headrest, two dishwasher-safe cup holders, and DuoGuard head-and-torso protection built around a rigid shell with EPS foam. Chicco also states the KidFit ClearTex Plus is GREENGUARD Gold Certified, meaning it’s been tested for low chemical emissions. It meets the FMVSS 213b frontal-impact standard too.
Buy it if: your child still needs highback support, you want built-in LATCH for a snugger unoccupied fit, or the GREENGUARD Gold certification matters to your family.
Skip it if: price is the deciding factor — it’s nearly double the Diono’s cost for a similar core job.
Diono Solana 2
The Diono Solana 2 with LATCH is a backless-only booster listed at $54.99 on store.diono.com. It’s rated for 40 to 120 pounds and up to 63 inches tall — the widest weight range and tallest published height of the three. Diono states the seat itself weighs just 6.1 pounds, making it noticeably easier to move between two cars or toss in a trunk than a highback model. It includes flexible LATCH connectors, two retractable cup holders built into a snack tray, and a machine-washable cover. Diono backs it with a standard 12-month warranty that extends to 36 months if you register the product. It also states an 8-year usable lifespan from the purchase date.
Buy it if: your child is already past the highback stage and you want the lowest cost per pound of weight capacity and the lightest seat to carry around.
Skip it if: your child still needs the head and side support of a highback shell, or your car’s headrest doesn’t reach high enough on its own.
How Do I Know the Vehicle Seatbelt Fits My Child?
The seatbelt fits correctly once the lap portion lies snugly across the upper thighs, not the stomach. The shoulder portion should also cross the chest and shoulder without touching the neck or face. That’s NHTSA’s own standard for proper belt fit. It’s the test that ultimately decides whether a child still needs a booster at all, not a birthday or a specific weight.
NHTSA also reports that 39% of children killed in car crashes in 2024 were completely unrestrained. That statistic covers all restraint types, not boosters specifically. But it’s a reminder that whatever system fits your child correctly, using it every ride is what matters. Most kids age out of needing a booster somewhere between 8 and 12 years old. That’s once they reach roughly 4 feet 9 inches and the adult belt starts fitting on its own.
Is the Chicco KidFit Worth Nearly Double the Diono Solana 2’s Price?
For most families, no — the Diono Solana 2 covers a wider weight range for close to half the price. The Chicco earns its higher price specifically for three things the Diono doesn’t offer: a highback mode with head and side support, built-in LATCH connectors with a SuperCinch tightener, and a GREENGUARD Gold low-chemical-emissions certification.
If your child has already outgrown the highback stage, and your car seats have headrests tall enough to support them, the extra $55 buys certifications and hardware most families won’t notice day to day. If your child still needs a highback shell, the more relevant comparison isn’t Chicco versus Diono at all. It’s Chicco versus the Graco TurboBooster 2.0, which also offers a highback mode for $40 less but skips LATCH and the GREENGUARD Gold rating.
How We Compared These Three Booster Seats
This comparison is built from each brand’s current published pricing and specifications — Graco, Chicco, and Diono’s own product pages. It also draws on NHTSA’s public booster-seat and proper-belt-fit guidance, and our own cost-per-pound-of-capacity calculation shown above. Crash-test and side-impact performance claims come only from what NHTSA, IIHS, or the manufacturers themselves have independently published. Where a spec wasn’t published by a brand, like a minimum height for the backless-only Diono, we said so rather than guessing. For more on how we source and fact-check comparisons like this one, see our editorial standards page.

FAQs About Booster Seats
Do all three of these booster seats have LATCH connectors?
No. The Chicco KidFit ClearTex Plus 2-in-1 and the Diono Solana 2 both include LATCH connectors for anchoring to the vehicle. The Graco TurboBooster 2.0 Highback compared here does not include LATCH and relies on the vehicle’s own seatbelt to hold it in place when unoccupied.
What’s the minimum age, weight, and height for any booster seat?
NHTSA and pediatric guidance generally set the minimum at 4 years old, 40 pounds, and about 44 inches tall, and all three boosters in this comparison share that 40-pound and age-4 floor. A child should also have outgrown their forward-facing car seat’s weight or height limit before moving into any booster.
Can a booster seat be used with just a lap belt and no shoulder belt?
Belt-positioning boosters like the three compared here are designed to work with a full lap-and-shoulder belt system, not a lap-only belt. If a seating position in your vehicle only has a lap belt, check that specific booster’s manual and your vehicle owner’s manual before using it there. Not every booster is approved for lap-belt-only installation.
How long will a booster seat last before my child outgrows it?
It depends on the child’s growth curve more than the calendar, since these seats are rated by weight and height rather than age. Most kids stay in a booster somewhere between ages 4 and 8-12, until they reach roughly 4 feet 9 inches and the vehicle’s own seatbelt fits them properly without one.
Are highback boosters safer in a side-impact crash?
We didn’t find independently published, apples-to-apples crash-test data comparing these specific three boosters in side-impact scenarios, so we’re not making that claim either way. What is well established is that a highback shell adds head and torso support a backless booster doesn’t have. That’s why guidance from booster makers recommends highback mode for vehicles without adequate headrests at that seating position.
Which of these three boosters is easiest to move between two cars?
The Diono Solana 2 is the lightest and simplest to move, at a stated 6.1 pounds with no highback shell to unclip. The Chicco and Graco can both be moved between cars too, but their highback shells add bulk and weight that make a quick swap more of a two-hand job.
Which Booster Seat Should You Buy?
All three boosters do the core job: getting a vehicle seatbelt to land where it actually protects your child. The Diono Solana 2 is the value pick once a child is past the highback stage. It covers the widest weight range for the lowest cost per pound of capacity. The Graco TurboBooster 2.0 Highback is a solid, no-frills highback option if you don’t need LATCH or a chemical-emissions certification. The Chicco KidFit ClearTex Plus 2-in-1 is worth its higher price specifically for LATCH, GREENGUARD Gold, and a highback mode in one seat. It doesn’t fit a child any better than the other two once the seatbelt lands in the right place.
