These are great under mattress when you use the metal matress supports instead of box springs. Keep the mattress level avoiding dipping in between the metal bars.

I have been searching for an inexpensive solution for my yoga studio flooring. These are perfect! Easy to put down & cut to form around walls & corners. Will be buying more to finish the rest of the room.

Perfect for our home playroom! Large size, durable and better price than anywhere with similar products. Started with one set, but I am getting more for our playroom and another set for our workout equipment!

Easy to install, even a "Grandma" could do it by herself! Great colors, but you can turn them over to the "black" side if you prefer. I love these and would purchase again!

We had this reversible flooring in my mom’s room under the elliptical that we use to exercise. My cat Betty became very ill over the course of a few days and we didn’t know why she was constantly throwing up strange pieces of a foreign object. Betty was becoming more lethargic and dehydrated to the point I had to rush her to the veterinarian. They gave her IV fluids and meds and sent us home. Unfortunately Betty did not get better so I had to return the Vet’s office for further testing and scans to see if she had a stomach obstruction with a foreign object. It wasn’t until this point that we found an entire area of the border of the foam flooring was missing at home and we made the connection that she was sick from eating this product. In summary, my cat Betty almost died and had to have emergency surgery to remove chunks of this foam flooring mat from her stomach. The vet showed me the pieces he was able to remove after the surgery. I couldn’t believe it. In the end, a $20 product cost me around $2000 so buyers with curious cats or kids please do not buy. I have pictures and receipts to prove this happened if anyone thinks I am making this up. -Abby

These are nice and thick and being a larger size go down very quickly and cover a large area fast. Sturdy enough to use in a work area in a garage.

These mats are great. Colorful and vibrant. Kids love it. I just wish there were 9 pieces in a pack to make a 3x3 square.

Used these to create a workout area in the basement. Easy to install and it was exactly what I needed.

Our friend has continued to thank us for the mats everytime he goes out on the road for a train show. They really help with leg and back fatigue.

It comes with 8 tiles which is great, but all tiles can only interlock on 2 of the 4 sides. This doesn't allow for adding more to make it squared set up.
