All About the Organic Cotton Mattress Protector

This incredible protector maintains a hygienic sleep surface while preserving your mattress's feel and performance.

This organic, shrink-to-fit, machine-washable mattress protector is designed to provide natural, breathable protection while preserving the feel and performance of your mattress surface.

Conventional mattress protectors are often made from stiff materials, creating a tight-fitting, non-breathable barrier between you and your mattress. While this mattress design provides efficient pressure-point relief, the wrong protector pad can recreate surface tension and inhibit body temperature regulation.

Customers praised this organic cotton protector for being breathable, chemical-free, and "soft" without bunching on adjustable beds. The stretchy knit fabric fits deep mattresses well and adds plush comfort. Shoppers appreciated that it doesn't cause sweating like plastic-lined alternatives and maintains size after washing.

  • No sweating like with plastic-lined mattress protectors.
  • This one is stretchy and fits perfectly with minimal bunching.
  • It adds a touch of plush when sleeping and being all natural was my main objective.

Amazing!!

I was searching for a natural, chemical free mattress protector for awhile. I wanted something of quality but at a decent price tag. Found this one, and my husband and I couldn't be happier. It stayed true to size after washing, it adds a touch of plush when sleeping and being all natural was my main objective. Delivered fast and efficient customer service!

It Fits!

This was the first mattress protector I've found that is purposely made larger so that when you wash it, it will shrink and fit! Yes, they tell you to pre-wash and dry it before using. After doing so, you will find it fits over the mattress without a struggle. It is a quilted knit cotton. The knit means it will stretch, unlike woven fabric that other mattress protectors use which doesn't stretch. The cotton allows it to breathe. Other protectors are either a polyester or poly/cotton blend which do not breathe as well. The stitching on this protector is good as well " it has not popped. And it is deep. There is no problem covering the entire mattress top, sides, and having extra for underneath.\nWell worth the price.

Perfect for adjustable bed

We got a new adjustable bed and I had difficulty finding a mattress cover that didn't bunch up. This one is stretchy and fits perfectly with minimal bunching when the bed goes through various positions.I highly recommend it.

Stretchy and Comfortable

Originally took delivery of my Berkeley Malmo mattress and it was reasonably comfortable but I found it firmer than it was in the store. Turns out my quilted protector I had from before was making the surface of the mattress tighter and firmer, ended up getting the Berkeley protector and it definitely is more comfortable with this, should have bought it from day one.

    Natural vs. Organic

    "Natural" and "organic" have distinct meanings. These differences largely stem from marketing tactics. Organic certificates are not safety certificates. It is best to view all organic certificates as marketing, not health or safety.

    If organic certification is important to you, please view our organic mattress collection. t•masc mattresses are made in Canada, and all materials are entirely third-party certified organic.

    Mattress & Sleep Company recommends reading our guide on the truth about chemicals in mattresses. This in-depth article discusses several critically important topics and helps distinguish between fear-mongering, marketing, and genuine facts.

    Remember, everything is a chemical. Water is a chemical (H2O). There is no such thing as a chemical-free mattress, just as there is no such thing as a chemical-free anything.
