A cover for a pool, hot tub or the like wherein the pool structure has an upper perimeter portion defining a pool area where water is contained. The cover has a first upper flexible sheet member having a first central portion and a first perimeter portion and a second lower flexible sheet member having a second central portion and a second perimeter portion. The first central portion of the first upper sheet member is separated from the second central portion of the second lower sheet by a support member. The support member has a sufficiently large vertical dimension to support the central portion of the first upper sheet member such that the first upper sheet member extends radially outwardly from the first central portion to the first perimeter portion at a moderate downward slope so that water and debris that fall on the cover move outwardly and downwardly from the first central portion of the first upper sheet member. The first perimeter portion of the first upper sheet member is attached substantially entirely around the second perimeter portion of the second lower sheet member and the first upper sheet member is spaced apart from the second lower sheet member by the support member thereby creating an insulating dead air space so as to provide heat insulation for water in the pool. A method for covering a pool structure or the like is also disclosed.
