Fast Delivery, great product. Would definitely recommend. Bought this seat for short trips on holiday. Compact seat that fitted easily into our luggage and was easy to assemble.

Excellent very pleased!

I actually bought this as a booster seat for my 5 year old to sit on in restaurants because shes not big enough to reach the table! It works perfectly! Inflates and deflates easily and folds up into handy carry bag to take along with you. Haven’t used it in the car yet but will be taking it on holidays with us. Excellent very pleased.

Thanks Shyann, it's a super useful little product! x
