Safety Covers are the best swimming pool covers. Insurance rated. They will protect Children, Pets, Adults and make for an easy spring cleanup. www.atlantapoolsafetycovers.com

I know i am late but for future people reading through this should also consider automatic pool covers if you are looking for all year round safety.  The safety covers mentioned above are more for winterization or covering your pool during a time you dont want to use it.  They take time to install and are not an in season friendly option.  

automatic safety covers like coverpools are a key switch operated safety cover that covers and uncovers the pool in a matter of seconds.  When installed by a professionaly trained installed they can easily hold the weight of multiple adults and children.

Loop Loc is a great product for safety fencing around pool areas.
