If your 5-year-old is ready to transition from a forward-facing car seat to a booster, you're probably feeling a mix of excitement (they're growing up!) and anxiety (is this really safe?). I get it, choosing the right booster seat is one of the most important safety decisions you'll make as a parent.
Here's the good news: when used correctly, booster seats reduce the risk of injury in car crashes by 45% compared to seat belts alone. But with dozens of options on the market, how do you choose the safest one for your child?
In this comprehensive guide, I'll walk you through everything you need to know about booster seat safety for 5-year-olds, review the top-rated options, and help you make the best choice for your family.
Is Your 5-Year-Old Actually Ready for a Booster Seat?
Before we dive into specific products, let's make sure your child is truly ready for this transition. Just because your child is 5 doesn't automatically mean they should be in a booster.
Check out this comprehensive guide about when to switch to booster seat.
Important: If your 5-year-old hasn't outgrown their harnessed car seat yet, keep them in it! Many modern forward-facing seats accommodate children up to 65-90 pounds. A five-point harness always provides superior protection compared to a booster seat.
High-Back vs. Backless Booster Seats: What's the Difference?
There are two main types of booster seats, and understanding the difference is crucial for safety.
High-Back Booster Seats
What they are: These have a full back that extends above your child's head, providing head and neck support.
Best for:
-
Vehicles without headrests or with low seat backs
-
Younger children transitioning from harnessed seats (the structure feels familiar)
-
Long trips where kids might fall asleep
-
Added side-impact protection
Pros:
-
Provides head and neck support
-
Better side-impact protection
-
Guides the shoulder belt correctly
-
More comfortable for sleeping
Cons:
-
Bulkier and heavier
-
More expensive
-
Takes up more space
Backless Booster Seats
What they are: A simple cushion that raises your child up so the seat belt fits properly.
Best for:
-
Vehicles with proper headrests or high seat backs
-
Older children who've outgrown high-back boosters
-
Travel and carpool situations (they're portable)
-
Vehicles with limited space
Pros:
-
Lightweight and portable
-
More affordable
-
Easy to store
-
Simple to move between vehicles
Cons:
-
No head/neck support
-
Less side-impact protection
-
Requires vehicle to have headrests
-
Child must be mature enough to maintain position
For most 5-year-olds: A high-back booster is the safer choice, especially if this is their first booster seat.
What Makes a Booster Seat "Safe"?
Not all booster seats are created equal. Here's what to look for:
1. Safety Certifications

R129 (i-Size) Regulation - The latest European safety standard with stricter side-impact testing

2. Side-Impact Protection
-
Deep side wings
-
Energy-absorbing materials

Clearly marked belt paths
-
Shoulder belt guides that prevent the belt from crossing the neck
-
Lap belt guides that keep the belt low on the hips
4. Stability Features
-
Non-slip bottom to prevent sliding
-
LATCH connectors (for high-back boosters) to keep the seat in place when empty
-
Wide, stable base
5. Ease of Use
This matters for safety! If a seat is complicated, you're more likely to use it incorrectly.
-
Clear instructions
-
Intuitive belt routing
-
Easy adjustments
6. Proper Fit for Your Child
-
Appropriate weight and height ranges
-
Adjustable features to grow with your child

Comfortable enough that they'll want to use it correctly

Special Feature Spotlight: Why the BubbleBum Teleport is Perfect for Modern Families
Let me dive deeper into why the BubbleBum Teleport deserves special attention, especially for families with active, travel-filled lifestyles.
The Travel Dilemma
Every parent has been there: you're packing for a trip, and you're faced with the impossible choice:
-
❌ Lug a bulky booster seat through the airport
-
❌ Pay expensive rental fees for a questionable car seat
-
❌ Risk your child's safety by improvising
The BubbleBum Teleport solves this problem elegantly.
How It Works
The telescopic design means it collapses down to about the size of a folded umbrella. When you need it:
-
Pull out the telescopic base
-
Lock it into position (takes about 10 seconds)
-
Place it on the vehicle seat
-
Thread the seat belt through the guides
-
Your child sits, and they're safely secured
When you're done, it collapses back down and slides into its carrying case.
Real-World Scenarios Where It Shines
Scenario 1: The Family Vacation You're flying to Florida for a week. Instead of gate-checking a bulky booster or paying $75 for a rental car seat, the BubbleBum fits in your carry-on. At your destination, it works perfectly in the rental car.
Scenario 2: The Carpool Rotation It's your week to drive the carpool, but you need four booster seats. Instead of trying to cram four regular boosters into your vehicle, you use portable BubbleBums that store easily when not in use.
Scenario 3: The Rideshare Situation You need to take an Uber to the airport. The BubbleBum fits in your bag, so your child can ride safely without compromising their protection.
Scenario 4: Grandparents' House Keep one at grandma's house without taking up space in their garage. When your child visits, it's ready to go.
Safety Without Compromise
Despite its portability, the BubbleBum Teleport doesn't cut corners on safety:
-
R129 Certification means it's been through rigorous side-impact crash testing
-
Proper belt positioning ensures the lap and shoulder belts sit correctly on your child's body
-
Non-slip base keeps it stable on the seat
-
Durable construction withstands repeated use
When the BubbleBum Might Not Be Right
The BubbleBum is fantastic, but it's not for everyone:
Not ideal if:
-
Your vehicle lacks proper headrests
-
Your 5-year-old still needs the structure of a high-back booster
-
Your child tends to slouch or sleep in the car (no head support)
-
This is their very first booster (start with high-back first)
Perfect if:
-
Your child has used boosters before and can sit properly
-
You travel frequently or need portability
-
You need multiple boosters for carpools
-
Your vehicle has good headrests
-
Your 5-year-old is mature and follows safety rules
How to Choose the Right Booster for YOUR 5-Year-Old
Every child is different. Here's a decision framework:
Step 1: Assess Your Child's Experience Level
First-time booster user? → Start with a high-back booster like the Graco TurboBooster or Britax Highpoint
Experienced booster user who's mature? → Consider backless options like the BubbleBum for flexibility
Step 2: Consider Your Primary Use Case
Mostly daily commutes in one vehicle? → Go with a full-featured high-back like the Clek Oobr or Chicco KidFit
Frequent travel or multiple vehicles? → The BubbleBum Teleport is your answer
Need multiple boosters on a budget? → The BubbleBum Teleport is your answer
Step 3: Check Your Vehicle
Vehicle has low seat backs or no headrests? → Must use a high-back booster
Modern vehicle with proper headrests? → Backless options like the BubbleBum work great
Small car or need three-across? → The BubbleBum Teleport is your answer
How to Properly Buckle Your Child in a Booster Seat?
Even the safest booster seat won't protect your child if it's not used correctly.
Here's the guide for how to buckle your child in a booster for maximum safety.
The Critical 5-Point Check (Every Single Trip):
-
✓ Back flat against the seat
-
✓ Bottom all the way back
-
✓ Lap belt low on hips/pelvis
-
✓ Shoulder belt across chest and shoulder
-
✓ Able to stay in position the whole trip
Common Booster Seat Mistakes to Avoid
Even well-meaning parents make these errors:
❌ Mistake #1: Transitioning Too Early
The fix: Keep your child in a harnessed seat as long as possible. Just because they can use a booster doesn't mean they should.
❌ Mistake #2: Using Backless Before They're Ready
The fix: Start with a high-back booster for the first 6-12 months to help them learn proper positioning.
❌ Mistake #3: Letting the Shoulder Belt Go Behind the Back
The fix: Teach your child that this is NEVER okay. The shoulder belt must always cross their chest.
❌ Mistake #4: Not Checking Fit Regularly
The fix: Every few months, do the 5-point check. As your child grows, positioning changes.
❌ Mistake #5: Moving to Seat Belt Alone Too Soon
The fix: Most kids need boosters until age 8-11 and 4'9" tall. Don't rush it!
❌ Mistake #6: Using a Booster in the Front Seat
The fix: Children under 13 should ALWAYS ride in the back seat.
❌ Mistake #7: Forgetting About Expiration Dates
The fix: Booster seats expire (usually 6-10 years from manufacture). Check the label!
Special Situations: What About...
Carpools and Other Drivers
If your child rides with other families, you have a few options:
-
Send your booster with your child - This is safest and ensures proper fit
-
Use a portable option like the BubbleBum - Easy for your child to carry
-
Keep a spare in the carpool vehicle - If it's a regular arrangement
-
Educate other parents - Make sure they know how to install it correctly
Pro tip: Attach a laminated card to your booster with quick installation instructions.
Taxis and Rideshares
This is tricky because most rideshare services don't provide car seats. Your options:
-
Bring a portable booster - The BubbleBum is perfect for this
-
Use rideshare services with car seats - Some cities offer this (like Uber Car Seat)
-
Avoid rideshares for young children - When possible, use your own vehicle
Never let your 5-year-old ride in a taxi or Uber without proper restraint.
Air Travel
Booster seats are not approved for airplane use. On planes, your 5-year-old should:
-
Use the airplane seat belt
-
Sit by the window (safest position for children)
This is one reason having both a regular booster and a portable option like the BubbleBum makes sense, use your standard booster at home, and bring the BubbleBum for the destination.
Children with Special Needs
Some 5-year-olds have special requirements due to medical conditions or physical differences. If this is your situation:
-
Consult with a certified Child Passenger Safety Technician with special needs training
-
Look into specialized restraint systems designed for specific conditions
-
Get your pediatrician's input on positioning and support needs

When Can Your Child Stop Using a Booster?
Your child can graduate from a booster seat when they pass the 5-point seat belt test mentioned in the following article: How Long Are Booster Seats Good For & When To Stop Using?
Final Thoughts: Safety Is Non-Negotiable
Choosing a booster seat might seem overwhelming, but remember: any properly used, safety-certified booster seat is better than none. The "best" booster seat is the one that:
✓ Fits your child correctly
✓ Fits your vehicle properly
✓ Fits your lifestyle and budget
✓ Is used correctly every single time
Your 5-year-old is at a wonderful age, curious, growing, and increasingly independent. But they still need your protection, especially in the car. Motor vehicle crashes remain the leading cause of death for children in this age group, but proper restraint use can prevent the majority of serious injuries.
Don't rush the transitions, follow the guidelines, and know that every trip with your child properly secured in their booster seat is an investment in their safety and your peace of mind.
Safe travels!
