Hot Tub Cover Lifter, Spa Cover Lift, Hot Tub Cover Lift Removal System Height 31-41 Inch Adjustable, Fit for Most Spa Hot Tubs

We put this lifter on our tub, no permanent modification needed, just gotta drain the tub and slide the plates under. https://a.co/d/0fRSpURO Edit: is the cover waterlogged or something? Usually the covers are just foam wrapped in plastic bag and then a vinyl or fabric cover.
