very easy to assemble

I am very happy with my purchase of these mats. They have many uses. The grey side down is best if you are using them on a smooth floor as it grips the floor better than the colored side. I kind of like how the colored side is bumpy-makes playing with toy cars on it different. The only thing I would ask to be changed is that they come in packs of nine so that you can make a full square.

Excellent quality.

Awesome buy

Bought these for a cattery floor to give my cats a place to lay off the concrete floor. Easy to clean. Worth the money

Bought for P90x2. Great while on your feet and non-slip on laminate wood. A bit rough on hands during push-ups and while exercising lying down.

I just purchased a 6x12 enclosed trailer with a ramp and used the mats for flooring on both the inside floor and on the ramp. Makes it look nice.

Great price great mats, toys r is sells 4 mats for this price. Love that you can pick colored side or just plain black.

The thickness and comfort is good but I expected it to come out square when together but it was a tile short

I started with only one pack and ended up with putting down a whole floor down in our play room. From wall to wall. They are easy to clean.
