This waterproof mattress protector is the BEST one I have ever used in my 53 years of marriage, using mattress protectors. High quality, easy to wash and dry, and easy to slip over the mattress.

Ok why is luxury in the title. It's plastic, noisy and took the comfort out of my bed. I'm return. Would be great for a child that wets the bed.

Have been using this product for other bed of mine past 4 years with multiple washes so far without any issue. I got one for king bed and fitted very well. Recommend this product.

No regrets!

Love it! My kids mattresses stay dry and they never noticed I put it on the mattress. It feels well made and I love the fact that it's cooling since it can get very hot where we live.

I wouldn't describe this as cooling... I think that is a misleading term. However, it is comfortable, doesn't make a lot of noise, and doesn't trap heat.

Product is OK and does the job it's supposed to. But, surface is very smooth, almost slippery and not as comfortable (for patient) as other brands. Won't reorder.

Nice mattress pad. Cooling waterproof.

Verified purchase

Fits mattress nicely. Didn't expect it to be as much vinyl on top but is still comfy and is not noisy. Wanted the cooling feature for new gel top mattress and also wanted to protect against spills since it is being used in a guest bedroom.

Satisfied

So far so good, no complaints on trapping hot air or making noises. I was little disappointed that it only protects the top of bed and not the sides.

This is alright for the price. Much better than the one I replaced. Con is, does not stay over corners of the mattress as well as I would like.

1. No, even though the fabric has good stretch, the TWIN size is based on a regular twin bed with length of 75 inches.

1. Yes, but not completely. It will help contain allergens and protect you from dust mites, but the problem, particularly with bed bugs is that this product the fitted style, using elasticated sides and no bottom. If you really want bedbug protection, we suggest you look at 6-sided, mattress encasements with zippers.
