Hello, due to the friction between materials, the presence of any layer of fabric on your mattress will not be 100% silent. However, our product is designed to minimize this effect while maximizing the protective benefits it offers – the prevention of spills & stains from coming into contact with your mattress.

RUINED a brand new mattress.
RUINED a brand new $1,700 organic mattress. Washed as directed and acutally doubled up using two of these protectors on my child's bed, just in case. He ended up having an accident one night and it seeped through through BOTH protectors. The bed reaks of urine now. WILL NEVER USE this company again. So furiuos as we trusted this brand.

Felt compelled to come and review this. I was searching all over for a quiet waterproof cover. I’ve gone through several. I trusted the reviews on this one and it turned out in my favor! So happy with this.

I don’t feel like this is temperature regulating. It doesn’t feel breathable and traps in heat, you wake up in a hot sweat, even taking covers off the heat is trapped in the bed, making it very uncomfortable to sleep. It also doesn’t fit the mattress snug at all, so it moved around and doesn’t offer adequate coverage protection of the mattress.

Sleeping on Plastic
Don't bother buying. This mattress protector is like sleeping on a sheet of plastic, and it's loud! Every movement creates a sound from the polyster plastic that it's made out of.

Not snug
Doesn't stay on well. Moves around and also causes top bed sheet to not be snug and the friction makes annoying noises.

Horrible. Slips off bed and bunches up. Defeats the purpose of a mattress protector.

NOT waterproof
This mattress cover leaked the first time it was used. I am so disappointed in Target for this poor quality item. It is falsely advertised and leaves the mattress wet every time.

Not waterproof
Mattress protector itself is ok—not noisy, doesn’t affect the texture of the bed. But it’s not waterproof. Pee on the bed and the mattress still stinks.
