The Bestway Pool Floor Protector consists of eight interlocking mats which sit beneath your pool or spa to protect the base from tears and abrasions. The foam mats are water-resistant and designed to withstand heavy pressure, enabling you to safely set up on a patio or decked area. Matting also reduces the amount of heat that escapes from the base of your pool or spa, enhancing insulation and cutting heating costs. Size H81.3, W81.3, D3.2cm. Weight 1900g.
