Very comfortable
Size: 36" X 24", Color: Grey, Size: 36" X 24", Color: Grey
Very soft and dries fast. I did the scoot test on them to test the grip and they passed with flying colors. Got them on a limited deal and it was worth every penny. I will be purchasing more in different colors as there are plenty of options. I haven’t washed them yet but if there’s an issue, I will definitely update this review. They are nice and thick and fell good on your feet.

Nice shower mat
Size: 50" X 30", Color: Navy
I have had it for almost a month now and run it through the washer and dryer. Its nice and soft, decent size I did not use a measuring tape to check how precise the sizing is. Absorbs the water when I step out of the shower well and doesn't feel wet or let anything through. Stays in place on the tile floor. Only challenge has been the robot vacuum cleaner gets trapped on it about half the time, but this might just be a testament to its thick nature.

Soft and washes well.
Size: 30" X 20", Color: Grey
These are great rugs and I keep going back and buying more. They are such a good value for money and they wash really easily. They don't slide or shed and they are very durable. They are very soft.So far we have them in both bathrooms and next to our bed.

Great Purchase
Size: 24" X 24" Contour Rug, Color: Beige
I picked these rugs (I purchased 3 of them) because it said its for elongated toilets. I have elongated toilets so I ordered for each room, they are a little large. I thought they would fit the toilet perfectly and not be large where it moves away from the side of the toilet. they are all very soft, like a shag rug, nice and thick and they come in many colors. The only thing I would change is the price of the light grey rug.

Good mat, good price, 'nuff said.
Size: 30" X 20", Color: Grey
While the photo suggests that this mat is enormous, it is a pretty good size at 30 x 20 inches. The chenille is very soft and feels nice on your feet. There is a rubber backing that prevents slippage on smooth bathroom floors. Overall there is nothing terribly noteworthy about this bathmat - it's a nice, high quality mat at a very good price. A good deal every day.
