CALM NITE Queen Mattress Pad Protector

I purchased this mattress cover to protect my futon from my cat's "accidents." She has separation anxiety & tends to pee on the couch whenever we leave (or she USED to, but we've managed to fix this issue, luckily!) & anyone with cats knows their pee is the absolute worst thing to get on your carpets or furniture bc the odor never goes away. Even with professional cleaning, we still had to buy a new mattress, not once but twice! We finally got this mattress cover to protect our (third!) futon mattress & so far it's been... Just okay. It fits perfectly, so that's a good thing. However the material is kinda uncomfortable. Since it's waterproof, it's made out of smooth, elastic, "swimsuit"-like material which isn't pleasant to sit on. Obviously if you cover it with blankets or bedsheets it's fine, but if you plan to sleep directly on this you'll probably find it uncomfortable. It's also only MOSTLY waterproof. My cat has peed on our futon 3 times since implementing this & the first time it blocked 100% of the liquid from reaching the mattress, but it seems like the absorbing quality has lessened since then. The next 2 times it only stopped about 75% of the liquid - some seeped through onto the mattress, to my disappointment. My theory after reading several other reviews is that washing the mattress cover completely destroys the waterproof quality, even if you follow the instructions. Usually these waterproof covers must be washed in cold water (sometimes warm is okay) & absolutely CANNOT be run through the dryer except to tumble dry, bc the high heat will damage the waterproof material. Knowing this, I washed it in cold water with nothing else in the machine except hypoallergenic detergent (gentle on delicate fabrics) & chose to air-dry by hanging it from my shower curtain rod for 24hrs. It takes a long time to dry btw since the material is meant to retain liquid, so I would recommend tumble drying, again with NO heat. After it was finally dry the material felt exactly the same, but the next time kitty had an "accident" like I said, some of the liquid seeped through onto the futon. It happened again the next time too. I'm still using this cover as a preventative measure since it still has most of its waterproof quality, but I no longer trust it to fully prevent "accidents" from damaging my mattress. If you actually want something 100% waterproof, look elsewhere.
