Well, I woke up to my dog throwing up right by my head at 5am. 🤢 It was very watery and nothing penetrated this matress pad. Not sure how it will hold up to pee or spilling a glass of water, but it works for what I needed it for. And it was easy to put on and stayed in place. Always a plus.
some moisture pads are moisture repellent not totally moisture proof. Before putting this on the bed I put water in it and rubbed the bottom of it to see if the water would come through and it didn't. Good product!! The comfortable padding, that's just another plus❤️
This is the best mattress protector I've ever owned. i need to always have one because i rescue animals, and when they get old and sick, well...they have accidents. This cover is so soft and plush I have even slept directly on it when just too tired to completely apply new sheets late at night (after the above described accident). I own two now because they're that good. The old ones are thin and plastic like AND they leak! Get this, you won't regret it. Fits my thick King bed just fine.
I have this on my bed bought a several years ago. Holding up really well. It's soft comfortable and washes well. Well made and Looks great and is still pristine white. Just bought another one for guest bedroom. I don't use it for any fluid so can't speak to that. I have a 4 1/2 inch topper on my bed and elastic fits over that and thick mattress.
This protector is awesome. We have another brand name that is thinner, but I discovered that it offers minimal protection and stuffed leaked thru to the mattress. This protector does not let anything leak through it so it actually protects your mattress!!
I bought this thinking I was getting a mattress protector. It was a pleasant opps though. This mattress pad added extra softness and makes you feel like you're being cuddled by your mattress. It fit great and stays in place. And it is waterproof, so it should help keep the mattress clean still. My only caution is that it does tend to hold more heat on your body, though - so if you prefer a cooler sleep, this might not be for you. But otherwise, would highly recommend for those looking to add a little comfort to their mattress.
Sometimes my grandson is in my bed and of course, some things can happen like spills or maybe he's young. He might pee to bed. So waterproof was my main reason for buying this, but it's surpassed my idea of how good it would really be. I washed it twice now it's held up nicely in a normal wash. I even put it in the dryer. I still have not had a problem. It looks nice. It's nice on the bed. It's comfortable doesn't feel like it's waterproof. It feels nice highly recommend us.
I bought this because it had a layer that keeps anything spilled on it from soaking into the mattress. It does that very well. Unfortunately, my dog for mad at me and urinated a huge puddle on my bed. The urine did not go through the pad...my mattress still looks like new. I would have given it 5 stars but the pad shrunk after being washed in cold water and dried on a low heat. It was a struggle to get the pad back on my mattress.
The positive points : Its soft and seems durable. packaged extremely well, arrived as scheduled. Negatives: Looking at the photo advertisement it appears to be thick," I got confused , I wanted a mattress topper it does state Pad I get it but that photo was a bit of a marketing tactic . i fell for it ,, lol .. closing :its a nice Pad I thought a pad was the same as a topper ?? I was wrong, still happy with my purchase .
The thickness and soft feel of this item is nice, not swishy sounding or loud like other mattress liners. But, it’s not at all waterproof. I wouldn’t even call it water resistant. My toddler had a small overnight accident, barely any pee but it still soaked right through this ‘waterproof’ liner
