I know its a few months away, heck I'm still trying to open my pool and clear it up, but not having any instructions on closing (I've just always tossed whatever the store said into the pool, put a pillow in and covered it up) I have a question.
Is more than one better than just one? I always figured the purpose of the pillow was two fold, one it helped to relieve pressure from the ice on the wall and two it brought the leaves and watery gook to a place I could reach it. So it got me thinking, what would happen if one got enough pillows to form a criss-crossing X like pattern and then covered the pool. What if you took it a step further and went all crazy and filled the entire surface with pillows, wouldn't the leaves and water then just roll off the sides of the pool? (although as I type this I suppose given a big enough storm the ground could be eroded away allowing for pool wall failure)
Also, what is the life expectancy of a pillow? The past few years mine either leak or pop over the winter and my cover ends up sagging, or falling in to the pool (and then I'm left with the mess I've got now
