I really Little Tikes take on the pool cover. Their pool comes with cover with locks to keep unauthorized people or kids out of your pool. I really like this idea because many the cover will stay on the pool.

Our experience has been the cover is a waste. We never been able to keep cover on that came with our easy set pool or a metal frame pool. If you notice the cover is placed over the rim of the pool and tied on. It never works. One good wind and it is gone so just do not bother.
