We ordered 2 mattresses for our two children. Unfortunately, nothing came of the bathing fun. DC go the first time into the water, both (!) Airbeds broke. The first 10 minutes, the second then a few minutes later. (We are normally gifted people sometimes even had lilos earlier in life and have the airbeds normally inflated by mouth, they are not drawn on the sand, and our children also normally played with it - they both weigh less than 35kg) , If further help: We bought the mattresses end of July 2014 because they were just reduced by 60%. Maybe it was a bad batch and therefore the Supersaver price .... real pity! :(
