Xspec 3/8" Thick 100 Sq Ft Steel EVA Foam Floor Exercise Gym Mats 25 pcs, Grey

I haven't installed these yet since I'm still in the process of setting up my above-ground pool, but I wanted to share my first impressions. The mats arrived well-packaged and all pieces were included. Right out of the box, they feel thick and durable, not flimsy like some other foam tiles I've seen. The interlocking edges seem sturdy and fit together easily during a quick test layout. I purchased these to use as a base under my pool, and based on the quality so far, they seem like they'll provide good cushioning and protection for the liner. The material also looks like it will hold up well over time. Once I get everything set up and tested, I'll come back and update my review, but so far I'm really happy with the purchase and optimistic about how they'll perform.
