These benches comprise two basic elements: the surface that you lie on and its base. They are built from the rigid foam known as “Styrofoam”, a material derived from high density, closed cell expanded polystyrene, providing long lasting strength combined with very light weight, and are designed to feature both electrical and hydraulic heating systems (for further information, please contact your AstralPool supplier). With either heating system, the surface of the bench should be covered to provide even heat distribution and a perfect finish. The surface of your bench has been specially treated to ensure optimum grip. The standard length for these benches is 2 metres. For other formats, please contact your AstralPool supplier.
