The Bestway ground protection mat is designed to protect your above-ground pool from wear caused by gravelly ground, sharp branches, and other dirt. Simply place the ground protection mat where you want to set up your pool. The mats not only protect the bottom of your pool but also provide excellent protection for your lawn. When water spills over the edge of the pool, it collects on the ground protection mat, preventing you from sinking knee-deep in mud when exiting the pool. Bestway ground protection mats are also ideal for inflatable hot tubs, kiddie pools, and mega water parks. This ground protection mat is suitable for pools (or other items) with a diameter of up to 4.57 m. Protect your pool and your lawn with the Bestway ground protection mat.
