bubblebum Inflatable Booster Car Seat - Blow Up Narrow Backless Booster Car Seat for Travel. Portable Booster Seat for Toddlers, Kids, Child - Black

The BubbleBum meets and exceeds the safety requirements of the FMVSS 213 (Federal Motor Safety Standard for USA). As with all booster seats, it is designed for use with a standard 3 point adult seat belt that has been approved to ECE Regulation 15 or equivalent.
The material we use is similar to that of a lifebelt making it durable and extra safe. The air bladder contains memory foam which add structural integrity and comfort. The BubbleBum adds boost to position the seatbelt and prevents slouching.

EXTREME TEMPERATURES
Do not expose to extreme temperatures, this includes leaving in a vehicle while inflated when not in use or storing above a heater. Continual exposure will cause the materials to deteriorate and the seat will deflate.
If you need to leave the BubbleBum in the vehicle when not In use, simply unscrew the cap on the valve and place out of direct sunlight eg in the trunk (boot) of the car.
If using in areas of high altitude, please note the seat may partially deflate when driving from low to high altitude.
Do not reinflate at high altitude as this will cause the seat to over inflate and puncture on return to low altitude. For this reason when flying ensure that the seat is deflated and the valve cap closed.

The BubbleBum backless travel booster is compact, narrow and light - making it perfect for vacations, car pools and play dates. The innovative design means folding is easy, making it packable, portable and convenient. The award-winning inflatable booster is also easy to blow up and install.
