The main safety flaw with the 'Tots in Mind' crib canopy was that it wasn't a full tent, rather a crib cover which was placed on top of the crib rails and tied down to them. It also had a roof which was a crossing rod structure. This posed a danger of the entire canopy collapsing downward, as well as leaving space between the canopy and crib for a child to jam extremities in. This new design however, is a full tent design in which the frame goes down all the way to the bottom of the mattress and leaves no potential open spaces. Also, when tied down properly, it's virtually impossible to collapse it as it pops right back up.
