Safety: The Banbaloo inflatable guardrail is the anti-knock safety system as effective as the old traditional barriers, it offers the child or baby a deeper and more pleasant sleep, because thanks to its soft touch it prevents unnecessary knocks and does not give the impression of being caged Recommended for over 2 years. Design: The protector has a triangular shaped tube with a completely flat extension. It is made of 0.2 mm TPU, this material is much stronger than PVC, so we will avoid punctures or air leaks. TPU is the most recommended material for children\'s products. Maximum efficiency: Thanks to its flat extension of 40 cm, we take advantage of the weight of the little one so that the protection remains associated with the bed. It adapts to the dimensions of the inflatable ramp: 132 x 16 x 14 cm, which are the ideal dimensions to perform its function perfectly. INSTALLATION: It is very easy to inflate thanks to a safety valve with deflate button that prevents air from escaping. To do this, it is enough to blow or use an inflator. Once inflated, the barrier should be placed on the side of the bed and adjusted between the fitted sheet and the mattress. TRANSPORTABLE: Thanks to its flexibility, it is very convenient to travel comfortably with the protector - it takes up very little space and can be stored in any suitcase - so that your little one sleeps safely at family or friends\' house, hotel, holiday rentals, camping, etc., and so you do not have to carry traditional heavy and bulky barriers.
