Super easy to open. Quick to inflate to normal size. I will say that the mattress itself is slightly wider than the box spring which seems odd. It hangs over the edge a bit. However, there is a note inside package that states due to the way these mattresses are made, this is not uncommon for dimensions to be a little off. I have read other reviews that stated these mattress have a chemical odor. I am especially sensitive to smells and there is zero odor when opening. Overall, for the price, this seems like a steal.
