I put these tiles right down on the sub flooring in my son's room. He is currently 11 years old and has a cat as well as allergies to dust. These tiles work great! With no carpet pad down, the allergens are almost nonexisten though he still has carpeting in his room and the end product looks amazing! It is colorful enough that he loves it, yet still ″adult″ enough that after he is finished using the room, I can turn it into an office without having to replace the flooring. It was easy to install and looks great! 2020-1-Infinite-Carpet-Tile-Assorted-1
It's a cool idea for a flooring. I like that some colors are colorful and others are more of the gray.
I wasn't too concerned about having a mix match floor so this was fine for me. The floor was lower cost than other options and I'm happy I can use them on my patio.
The product has a plastic film on that back that you remove before putting the carpet on the ground. The adhesive was good and they seem to stay well so far.
