This is a longer lasting cover. Our aluminum cover will withstand the abuse from large dogs, cats that scratch, and rodents that use the foam and vinyl for nesting material. Protection for children should be an overriding consideration when recommending the BE-LITE ALUMINUM SPA COVER. Snow loads and weather considerations are not a concern when you have our aluminum spa cover as the cover won’t collapse in the middle due to weight; heavy snow load, pets or children. Our covers have no issues with odor or mildew as they don’t soak up water. Our covers simply offer superior protection and longevity.
