Designed by a UK-based company, the tiles line the entrance of the company's store. They make the floor appear curved when it's actually completely flat and its psychedelic design spooked many on Reddit and Twitter.
"I wonder how hard it is to overcome the visual cue and run over that with your eyes open?" wrote a Redditor.
Another wrote, "I feel like this will cause more falls than it prevents".
However, the illusion only works from one direction. Here's what it looks like when you're leaving the store.
And if the floor is too much to handle for you, you can always use the back door.
Last month, a flat carpet which appeared to show holes all over its surface had gone viral.
