These are beautiful seats however after less than 5 months of use 24 oof the seats which are not in constant use are broken.  The base does not seem to have been properly secured and we cannot repair it as it is internally damage in a sealed area of the seat.  Wobbling terribly and feels like its going to break beneath us therefore cannot be used, nothing to do with the parts we had to put together as is is not accessible to us for fixing. Very disappointing and not exactly a cheap purchase !!
