Hello! I have an above ground Coleman pool. I’ve had a Confer 7000 ladder for 2 seasons. This season, the ladder is very unstable. It leans very badly to one side when we use it and I feel like it will collapse and day now. We’ve taken it apart and reassembled it several times and nothing helps. It’s usually adults that use our pool so we need a sturdy ladder. Anyone have tips or tricks on how to make this ladder more sturdy?
