I ordered these mats several months ago and really liked them. They were thick and durable, reversible and fit together well. I recently ordered another set and was very unpleasantly surprised. The mats I received are a different color, only have the pattern on one side, and have a strong chemical smell to them. Plus they feel extremely cheap and flimsy, and arrived with some damage to them (obviously not from the shipping--as the box was fine). On top of that, they do not fit together with the other tiles I purchased. I am very disappointed and will be returning these.

Update: If you order more than one set of these mats (at different times), make sure they are from the same seller. The mats from Step 2 sold by Amazon are actually great quality..thick, odorless and fit well together. The tiles I reviewed above were from a different seller and were a completely different brand. Some of the sellers are attaching the wrong items to this item description--so be careful.
