The Combi Kobuk is the highback booster I keep in my trunk for carpooling duty. At just 7.5 pounds, it’s one of the lightest highback boosters available, and the built-in cup holder plus removable armrest padding make it comfortable enough for my kids to use daily without complaining. The EPS foam shell provides genuine side-impact protection, and the seat belt guides make proper belt positioning easy for older kids to manage themselves. For families who need a portable, affordable highback booster, the Kobuk delivers.
This review covers who the Kobuk works best for, its safety features, full specs, and how it compares to the Graco TurboBooster — the bestselling highback booster on the market.

Who is the Combi Kobuk best for?
The Kobuk is ideal for parents who need a lightweight, no-fuss highback booster that’s easy to install, move between vehicles, and let older kids buckle themselves into. The seat belt guides are color-coded and intuitive — even a 5-year-old can learn to route the belt correctly. At 7.5 pounds, it’s easy to carry from one car to another, making it practical for carpooling, shared custody situations, or grandparent vehicles.
The height-adjustable headrest with 10 positions accommodates a wide range of child sizes (33-57″), and the removable back converts it to a backless booster when your child outgrows the highback. The EPS foam throughout the shell absorbs energy during side impacts. However, there’s no LATCH system — the seat is positioned by the vehicle seat belt running through your child. If you want the stability of LATCH, consider the Clek Oobr or Graco Nautilus 65 instead.

Safety ratings
The Combi Kobuk meets all federal and JPMA safety standards. The EPS (expanded polystyrene) foam that lines the shell is the same energy-absorbing material used in bicycle and motorcycle helmets. Deep side walls around the torso and the adjustable headrest with side wings help keep your child properly positioned during a side-impact crash.
Proper belt fit is the most important safety factor in any booster seat. The Kobuk’s color-coded belt guides route the shoulder belt across mid-chest and the lap belt low across the hips, which is exactly where they need to be. Teaching your child to use these guides correctly is the single best thing you can do for their safety in this seat.
The Kobuk expires 8 years from manufacture. Check the label on the bottom of the seat.

Key features
Ultra-lightweight design. At 7.5 lbs, the Kobuk is about half the weight of premium boosters like the Clek Oobr (20 lbs). This matters for carpooling parents, shared custody families, and anyone who moves the booster between vehicles regularly.
10-position headrest. The fine-grained height adjustment means you can dial in the exact right position as your child grows. The headrest should be positioned with your child’s ears between the side wings.
EPS foam shell. The same energy-absorbing material used in safety helmets lines the entire shell, providing meaningful side-impact protection at a budget price point.
Combi Kobuk vs. Graco TurboBooster
| Feature | Combi Kobuk | Graco TurboBooster |
|---|---|---|
| Weight range | 33 – 100 lbs | 40 – 100 lbs |
| Seat weight | 7.5 lbs | 8.2 lbs |
| Headrest positions | 10 | 6 |
| Cup holders | 1 | 2 |
| Armrests | Padded, removable | Padded, integrated |
| EPS foam | Yes | Yes |
| Machine washable | Yes | Yes |
| Price | $$ | $$ |
Both are solid budget highback boosters. The Combi Kobuk has more headrest positions (10 vs. 6), starts at a lower weight (33 vs. 40 lbs), and is slightly lighter. The Graco TurboBooster offers two cup holders and wider brand availability. Either is a good choice — pick based on availability and which fits your vehicle seat better.
What’s included
The Kobuk comes with the highback/backless booster, integrated cup holder, and removable armrest padding.
Frequently asked questions
Is the Combi Kobuk safe without LATCH?
Yes. Most booster seats don’t have LATCH — the vehicle seat belt running through your child and the belt guides is the primary safety mechanism. LATCH adds stability but isn’t required for booster-age children.
When should I remove the back and use it as a backless booster?
Keep the highback as long as it fits (up to 57″). The headrest and side wings provide head and neck protection. Switch to backless only when your child exceeds the highback height limit and your vehicle’s headrest adequately supports their head.
Can my 3-year-old use the Kobuk?
Only if they’re at least 33 lbs and 33″ tall. However, most safety experts recommend keeping children in a 5-point harness as long as possible (typically until age 4-5 and 40+ lbs). A harness seat like the Graco Nautilus 65 provides significantly better protection for younger children.
Our verdict
The Combi Kobuk is the best lightweight highback booster for families who need portability and value. The 10-position headrest, EPS foam protection, and 7.5-lb weight make it practical for carpooling and multi-vehicle use. It’s not as rock-solid as a LATCH-equipped booster, but for the price and weight, it delivers excellent safety and comfort.
