Both products cater to the same weight range of 40 to 100 lbs, making the Cosco a more economical choice without compromising safety or functionality.
Design and Portability
In terms of design and portability, the BubbleBum features a unique telescopic design that allows it to compact down to 40% of its size, making it ideal for travel. This model includes a shoulder strap for easy carrying, which is an advantage for families on the go. Conversely, the Cosco Kids Topside Booster is lightweight and compact but lacks the foldable feature of the BubbleBum. While both seats are designed for easy transport, the BubbleBum’s innovative design clearly stands out for frequent travelers.
Comfort Features
When evaluating comfort, both booster seats offer distinct advantages. The Cosco Kids Topside Booster boasts extra-plush padding, enhancing the comfort level for longer rides. This plush design is aimed at making car trips more enjoyable for children. On the other hand, the BubbleBum offers a padded seat and a non-slip base for stability, ensuring a secure and comfortable experience. Parents should consider their child's comfort preferences when deciding, as the Cosco appears to prioritize plushness more explicitly.
Safety Certifications
Safety is paramount in child car seats, and both models excel in this area. The BubbleBum Teleport is certified by the USA Baby Safety Alliance, meeting FMVSS 213 and R129/04 standards, which are recognized as some of the highest in the world. The Cosco Kids Topside Booster, while not detailing specific certifications in the provided data, is designed for children weighing 40-100 lbs, emphasizing its commitment to safety. Ultimately, the BubbleBum’s explicit safety certifications may give it an edge for safety-conscious parents.
Ease of Cleaning
In terms of maintenance and cleaning, the Cosco Kids Topside Booster offers a machine-washable and dryer-safe seat cover, making it very convenient for parents dealing with spills and messes. In contrast, the BubbleBum features a removable, machine-washable cover, but the specifics of its cleaning process are less straightforward compared to the Cosco. Both seats allow for easy cleaning, but the Cosco’s dryer-safe feature may be more appealing for busy families.
Versatility and Usage
The versatility of both booster seats is noteworthy. The BubbleBum is marketed as an everyday booster that also serves as a travel seat, making it suitable for various situations like school runs and taxi rides. Its compact design allows for easy switching between vehicles. Meanwhile, the Cosco Kids Topside Booster is designed to grow with your child, making it suitable for kids up to 57 inches tall. Both products cater to a similar user demographic, but the BubbleBum appears to better accommodate varying travel needs.
Customer Popularity
In terms of sales rank, the Cosco Kids Topside Booster is currently ranked 4,210, while the BubbleBum follows with a sales rank of 6,980.

Which should you buy?
Deciding between the BubbleBum Teleport Backless Booster Car Seat and the Cosco Kids Topside Booster Car Seat ultimately hinges on personal priorities. If you are looking for a travel-friendly, compact seat with top-notch safety certifications, the BubbleBum may be your best bet. However, if budget is your primary concern, or if comfort is a driving factor for your child, the Cosco offers excellent value and has a slightly higher popularity ranking.
