yesHiccapop UberBooster Specifications
The Hiccapop UberBooster is an inflatable backless booster seat certified to FMVSS 213 for children 40–110 lbs. Weighing roughly 1.3 lbs deflated, it packs flat into a child's backpack and inflates in under 20 seconds — making it a compelling option for families who need a portable ground-transport booster at the destination. It is not FAA approved and cannot be used in flight. At $45, it is among the most affordable travel boosters on the market.
- The UberBooster is rated for children 40–110 lbs, ages 4–11.
- The inflated footprint is ~ 14.5 × 14.5 inches, allowing three seats across most bench seats including compact vehicles.
- The seat is backed by a lifetime guarantee.
- Ideally used for older children who are mature enough to remain appropriately positioned throughout the duration of the drive, without slouching.

In-Flight Restrictions & Ground Travel
The Hiccapop UberBooster cannot be used on aircraft. Its value proposition is entirely ground-side: it deflates to 1.3 lbs for in-flight carry-on storage and inflates in under 20 seconds for immediate use in taxis, rental cars, and rideshares upon landing. For wider seats, it will fit with the armrest raised.
The UberBooster is a ground-only travel booster — its value is the pack-flat convenience for post-flight ground transport in taxis, rideshares, and rental cars, not in-flight use.

Best For
Older Kids
For older kids who have outgrown a traditional five-point harness, and are mature enough to sit safely throughout the ride. At 1.3 lbs deflated, the UberBooster fits in a personal item during the flight and inflates in seconds for immediate use in taxis, rideshares, and rental cars after landing.
Parents managing carpool or rideshare pickups
Per Hiccapop's documentation, the seat inflates in under 20 seconds and its narrow footprint allows it to fit between two traditional car seats. A 9-year-old can carry it in their backpack and inflate it independently.
Budget-conscious families needing a secondary or backup booster
At $45 with no expiration date and a lifetime guarantee, the UberBooster is a low-risk secondary seat for grandparents' vehicles, carpools, or occasional travel where a full-size booster is impractical.
Three-across families in compact vehicles
The 14.5" inflated width allows three UberBooster seats across most bench seats, including smaller sedans and compact SUVs where rigid 17–23" boosters cannot physically fit three abreast.
Key Features
Inflatable Vinyl Construction
The UberBooster is constructed from double-thick rigid vinyl with steel belt loops and non-skid silicone beads on the underside. The thick vinyl bladder is designed to resist bursting and deflating even on bumpy roads. The contoured air-cushion design provides a softer ride compared to hard-plastic boosters, though it lacks the rigid side support of conventional seats.
15-Inch Compact Footprint
The inflated footprint just under 15-inches— narrower than most backless competitors. This compact footprint is the UberBooster's primary vehicle-compatibility advantage: most vehicles can fit three UberBoosters across the rear bench, including smaller sedans that cannot accommodate three full-size boosters.
Pack-Flat Travel Design
Deflated, the UberBooster collapses to approximately 1.3 lbs and fits into the included carry bag, which is compact enough to slide into a child's school backpack or a luggage side pocket. There is no hard frame or rigid components, so the deflated seat takes the shape of its container. For families flying to a destination where they need a booster for ground transport, the UberBooster eliminates the need to check or gate-check a full-size booster.
Shoulder Belt Positioner Strap
The UberBooster includes a shoulder belt positioner — a clip at the end of an adjustable strap that attaches to the inflated cushion and guides the vehicle shoulder belt to a safer position on the child's body. Parents should check the shoulder belt position at the start of each ride to confirm the belt crosses the shoulder — not the neck — and the lap belt sits low on the hips.
Real-World Scenarios
Rideshare from airport to cruise with an 8-year-old at 62 lbs
This is the UberBooster's ideal use case. Deflated and in your carry-on, inflate in under 20 seconds at the curb. The 62-lb child is well within the 40–110 lb range; the compact footprint fits any rideshare back seat.
Daily primary booster for a 5-year-old on the school run
The UberBooster is better suited as a travel or backup seat than a daily-driver primary. At 5 years old, most children will not be developmentally mature enough to use this correct 100% of the time - and would be best served in a five point harnessed seat, or highback booster offering extra postural support.
Flight cabin use with 6-year-old at 49 lbs
The UberBooster cannot be used in flight per 14 CFR 121.311(b)(2)(ii). Boosters are prohibited in aircraft cabins regardless of weight or size. The child uses the aircraft lap belt during the flight.
Extra seat for Carpools
At $45 with a lifetime guarantee and no expiration date, the UberBooster is a practical secondary for grandparents, babysitters, or carpool vehicles. The quick inflate/deflate means it stores flat until needed.
How It Compares
The BubbleBum is also an inflatable backless booster certified to FMVSS 213, deflating to under 1 lb — lighter than the UberBooster at 1.3 lbs. BubbleBum has a slightly narrower footprint, while the UberBooster offers better side bolsters and a more stable feel. Neither is FAA approved. Choose BubbleBum for maximum compactness; choose UberBooster for a firmer seated feel.
Read full reviewThe Mifold original is a hard-plastic belt-positioning booster that grips the vehicle seat rather than elevating the child — different engineering from the UberBooster's inflatable cushion approach. At approximately 1.5 lbs, they are similar in pack weight. The mifold folds flat without deflation steps. Neither is FAA approved for flight.
Read full reviewThe Mifold comfort adds padded side supports and an adjustable shoulder clip to the Original's fold-flat design, offering a more comfortable riding experience than either the Original or the UberBooster. The Comfort is heavier but still travel-compact. Neither is FAA approved. At comparable price points, choose the mifold Comfort for padded daily comfort; choose the UberBooster for maximum pack-flat convenience and three-across width flexibility.
Read full reviewPer WAYB's published documentation, the Pico is an FAA accepted 5-point harness travel seat weighing approximately 8 lbs — dramatically different from the UberBooster's inflatable booster design. The Pico is aircraft-approved for children 22–50 lbs; the UberBooster covers 40–110 lbs for ground use only. For families whose child is transitioning out of a harness, the UberBooster at $45 offers ground-only booster convenience; the Pico at $399 provides FAA accepted in-flight protection for younger or lighter children.
Read full reviewTravel Tips for the UberBooster
Inflate Before Customs or Curbside
Inflate the UberBooster while waiting for luggage at baggage claim or at the rideshare pickup curb — not in the vehicle. Inflation takes under 20 seconds. Inflating before entering the vehicle prevents awkward positioning in a cramped back seat and lets you verify a full, firm inflation before the child sits down.
Check Headrest Height Every Trip
A backless booster requires the vehicle headrest to support the child's head at ear level or above. Before each ride, confirm that the vehicle seat's headrest reaches at least to the top of your child's ears when seated. If no adequate headrest is present, the UberBooster should not be used in that seating position.
Deflate Fully Before Storing
Fully deflate the UberBooster and fold it before placing it in its carry bag. Partial deflation causes the seat to bulge in the bag and increases the risk of valve stress over time. The vinyl bladder should be wiped down with a damp cloth and dried before storage to prevent mildew on the interior surfaces.
Readjust Shoulder Belt Clip Each Ride
The UberBooster's shoulder belt positioner strap can slide and shift during a ride. At the start of every trip, verify the shoulder belt crosses the child's shoulder — not the neck — and the lap belt sits low across the hips, not the abdomen. Instruct children old enough to reposition the belt themselves to alert adults if it moves during the ride.
Pack in Personal Item, Not Checked Bag
At 1.3 lbs deflated, the UberBooster fits easily in a personal item alongside your other carry-ons. Checking it in a suitcase risks it arriving at baggage claim deflated but potentially bent or sat-upon by other luggage. Carrying it on ensures it is accessible immediately after landing for the first ground-transport leg.
Frequently Asked Questions
Is the Hiccapop UberBooster FAA approved for use on airplanes?
No, The UberBooster is not approved for use on aircraft. Additionally, per 14 CFR 121.311(b)(2)(ii), booster seats of all types are prohibited for use in the aircraft cabin on US commercial carriers. The UberBooster must be stored deflated in carry-on luggage during the flight.
What are the weight and height limits of the Hiccapop UberBooster?
The UberBooster is rated for children weighing 40 to 110 pounds and measuring 43 to 62 inches tall. The 40-pound minimum aligns with the standard minimum for belt-positioning boosters in the US, which also requires children to be at least 4 years old and able to sit properly for the duration of the trip. The 110-pound upper limit is generous and extends the UberBooster's useful life through older elementary-school children. Always confirm the seat belt fits correctly — lap belt low on hips, shoulder belt crossing the shoulder not the neck — at both ends of the weight range. Velivolo CPST Experts recommend waiting until children are at least 5 years old, and developmentally mature enough to maintain an upright position in the vehicle before transitioning to a booster seat.
How do I inflate the Hiccapop UberBooster?
The UberBooster inflates with a few breaths directly into the valve — no pump is required. Per the product page, inflation takes under 20 seconds. To inflate, open the valve cap, press your mouth to the valve, and blow firmly until the seat is fully firm. Close and secure the valve cap completely before placing the child on the seat. A properly inflated UberBooster should feel rigid and not compress noticeably under the child's seated weight.
Does the Hiccapop UberBooster have an expiration date?
No, FMVSS 213 (the booster seat standard) does not require an expiration date. It should easily last until your child transitions out of a booster. And if it ever fails, remember, it has a Lifetime Guarantee.
Can I fit three Hiccapop UberBoosters across the back seat?
Three UberBooster seats fit comfortably across the bench seat of most cars. The inflated footprint is 15 inches wide. Three seats at 15 inches each require 45 inches of bench width, which most full-size sedans, minivans, and mid-size SUVs provide. Compact vehicles with narrower rear benches should be verified before counting on the three-across configuration. The UberBooster is a good option for 3 across solutions.
Is the Hiccapop UberBooster safe? How does it perform in crash tests?
The UberBooster meets and exceeds FMVSS 213, the US federal safety standard for booster seats. Many CPSTs classifies it as best suited for travel, carpools, and rideshares rather than as a primary daily-driver.
How does the Hiccapop UberBooster compare to the BubbleBum inflatable booster?
Both the Hiccapop UberBooster and the BubbleBum are FMVSS 213 certified inflatable backless boosters at similar price points ($39–$49). Neither is FAA approved for aircraft use. The BubbleBum is slightly lighter (under 1 lb vs. approximately 1.3 lbs) and narrower, making it marginally better for very tight three-across situations. The UberBooster has side bolsters and a firmer seated feel that some children find more stable, and its grippy non-skid underside prevents sliding on leather seats more effectively. Per Velivolo CPSTs' review, the UberBooster stays put on the vehicle seat better than the BubbleBum, which can feel unstable when over-inflated. Both are more ideal for travel and secondary seats, than for primary daily boosters.
What vehicle seating positions can the UberBooster be used in?
The UberBooster should only be used in vehicle seating positions that have an adequate headrest. As a backless booster, it provides no head or side support of its own — the vehicle headrest must reach at or above the child's ear level when seated. The seat must be used with a three-point lap-and-shoulder belt; it cannot be used with a lap-only belt. The rear center position can be used if it has both a three-point seat belt and an adequate headrest. Always confirm both the belt fit and headrest height before using this booster for a child in an unfamiliar vehicle.
What is the difference between the Hiccapop UberBooster and the mifold Grab-and-Go?
The Hiccapop UberBooster and the Mifold represent two different engineering approaches to compact travel boosters. The UberBooster is an inflatable vinyl cushion that elevates the child so the standard vehicle belt positions correctly across the body. The mifold Original is a hard-plastic grab-style booster that clamps to the vehicle seat and guides the belt to the child's body without elevating the child. The mifold Original folds without any deflation steps, making it slightly faster to deploy. The UberBooster provides an air-cushion comfort advantage on longer rides. Both are FMVSS 213 certified, neither is FAA approved, and both weigh under 2 lbs packed.
