Bubblebum Car Booster Seat, Black

Product information

BubbleBum is a lightweight car booster seat that inflates, so it's easy to store and transport when not in use. It's also an ideal choice if you're trying to fit three booster seats along the back seat as it will fit into a smaller space than most solid booster seats.
The BubbleBum comes in a convenient carrying bag, and has shoulder belt positioning clips in place of arm rests. It deflates after use, and weighs just 600g, allowing it to be stored in a backpack, flight bag, trunk or even a large purse. It's an ideal choice for holidays, trips to grandparents to play dates.
The unisex design is not only comfortable, it can also be wiped clean in case of spilled snacks or drinks.
Easy and quick to inflate, it takes less than 30 seconds. Simply blow into the valve at the back. The inflatable inner is made from the same material as life rafts and the seat cover and webbing help the seat stay rigid.

Q & As

Bubblebum Car Booster Seat, Black 3.8 5 4 4
Great little booster seat! We took two of these booster seats with us on holiday to Portugal last month - just a brilliant invention. Fit easily into my sons backpacks, really light and small when rolled up in their bags. It was so handy when we picked up the Fiesta hire car to just quickly blow them up and seat everyone. We also have a 13 year old and the car would have been too small for the solid plastic booster seats so it did save us money on 2 hiring seats and taking a bigger car! Our boys call them their whoopee seats and like sitting on them, we now use them back home each day. Buying two for granny now for her to use when she's doing school pick ups as she has a small car too. Good money saver. 05 October 2014
Great for travel! I took this seat on holiday for my nephew to use in France. It took up so little space in my flight hand luggage and seemed really secure when attached in the car. 16 September 2014
Useful for holidays and small gaps We bought the bubble bum to take on holiday for my 4 year old. We used it for a week and my son even fell a sleep a few times whilst sitting on it. We never had a problem with slippage and the seat belt held my son in place well. I like how it has an adjustable strap to stop the seat belt cutting in to the child's neck. Since being home my son has asked to use it as he finds it more comfortable then his usual seat, however obviously this is obviously not as safe due to not having the high sides. We have used it when needing to squeeze an extra person in the middle seat, which is handy and my husband will be using it for the school run in September. 26 August 2014
Doesn't feel safe, too slippery I bought this booster based on the product descriptions which boast about their compact size and portability for travel etc, but ultimately when it comes down to it, safety is all that matters. my 5 year old complains about sliding off it , it being uncomfortable, which is a bad sign. When driving, I looked back and observed that the seat is in fact unstable and slides around when the car is in motion. The red clip on the side is supposed to help keep it in place with the seat belt, but this actually makes it lopsided and contributes to it sliding around in the car. This only seems to work reasonably well if its used as a middle seat booster, bolstered by 2 other car seats. All in all, I would not recommend it! Very disappointed and ended up buying the much more stable john lewis booster seat instead. 10 February 2014
