Polyester Imported While most other products are not machine dryable or can only be washed a few times (read their small print), our GORILLA GRIP 15.74 Inch x23.62 Inch Bath Rugs have been tested and can be machine washed and machine dried time and time again. We use the more expensive TP Rubber backing (not PVC or glue) which is much stronger and durable for long lasting use. Valentine bathroom rugs! Pamper your feet! Our bath mat features a luxurious, soft pile that soothes tired feet and shields toes from the cold floor. The density and plushness of our pile surpasses that of most other brands. High-pile, thick Chenille fabric helps save your floors from dripping water while you’re stepping out of the bath, shower, or getting ready by the sink. Moisture is trapped in the mat’s deep pile, allowing the rug to dry quickly and cleanly. Place rug on CLEAN DRY SMOOTH FLOOR only. Water under rug can cause it to slip. Keep bottom of rug dry. If you are not satisfied with your rug or if you decide that this is not for you, then please do not hesitate and reach out to us through Amazon at any time for either a refund or replacement.
