Works great under my carpet in front of washer dryer.

Received 42 light gray tiles in seven packs. The first pack of six had divet (pit) defects of various sizes or "skid marks." Opened the next pack and found the same types of problems. Contacted Wayfair customer support and uploaded three photos. Was told to check all the received tiles... After this tedious task, found just one tile in a perfect condition (without any visible issues). Wayfair accepted the return.

I purchased these to be used under a small kids' pool on my backyard porch and they provided the perfect amount of cushion. They are also sturdy and easy to clean.

There were different tones of gray. Very inconsistent

perfect for my exercise room. easy to put together.
