Wery nice comfy mats. Lock together well and wear well

Got these 1 inch interlocking foam mats to put underneath my hot tub. They helped to prevent heat loss or cold transfer from the Concrete below. The 1 inch foam serves good insulation… It’s also extremely comfortable under your feet. I’ve stood on half inch foam tiles and they’re not nearly as comfortable as these and these were the same price. The only negative I can come up with (and you could see it in the very last image) is the edges started curling up from the outside heat. I don’t think this would’ve happened if they were indoors so if you plan to put them outside like I did you might run into the same issue. On cold days, they would continue to lay flat so I do think it’s a heat cause it effect. Other than that, I highly recommend these over any of the other foam mats.
