There’s two answers to that.
If you mean one of our helium balloon bouquets, they all come with strings and metal / balloon weights at the bottom, so that they don’t fly away. So yes, they would “stand” on the floor on their own.
In case you’re looking at products like our very popular “Balloon Hug” or one of our balloon stands like the “Single Number Balloon Stand“, which are air-filled, then the answer is also yes. They have a wide enough base to stand on their own, to be placed on tables, stools or on the floor.
