The Pool Pillow Pal connection system makes installing and centering your pool air pillow easy. It consists of 2 specially designed flexible patches; one attaches to your air pillow, and the other to the underside of your winter cover. Connect them together and float the integrated pillow and cover on your pool as one unit. No more ropes or ties necessary, and the pool pillow pal keeps your air pillow perfectly centered under the winter cover.
