Are you concerned about SIDS and your baby?

We are Campaigning to Prevent SIDS.

Why Donate?

Contrary to prevalent belief, SIDS can be prevented.

We are seeking to form a Scientific 501c(3) Nonprofit to Research SIDS.

We have no financial interest in the sale of BabeSafe® Mattress Covers.

At Baby Mattress Covers, LLC we are convinced that using the New Zealand SIDS prevention method described on this website will protect your baby from SIDS.  Fully stopping SIDS..., it sounds to be totally incomprehensible doesn’t it.  But since 1996 in New Zealand there has not been a single SIDS death on a BabeSafe® wrapped mattress when the specified bedding, of 100% cotton bedding with no padding fill, has been used.  Worldwide there have not been any SIDS deaths reported on a BabeSafe® wrapped mattress when the Bedding Instructions have been followed. With more than 245,000 users in New Zealand..., No SIDS when using the specified bedding.

A Nutshell Summary of Mattress-Wrapping Against SIDS:

 ◽ Put a BabeSafe® mattress cover gas barrier between your baby and their mattress.

 ◽ Use 100% cotton bedding under and over your baby. Do not use polyester, acrylic or Rayon bedding.

 ◽ We are Campaigning to Prevent SIDS.

So, you ask, Why Should I Donate?

The two scientists, Barry Richardson in the UK and Dr. TJ Sprott in NZ that realized the cause for SIDS, felt that knowing its simple truth would be enough and everyone would be convinced to protect their babies by wrapping their mattresses.

Mr. Richardson first tried to protect the concept behind Mattress-Wrapping so it could be published in medical journals. But the media was very aggressive to publish the reason behind cot death (SIDS). Eventually he allowed the TV stations in the UK to help investigate the cause of SIDS.

But the TV stations stopped short with just sharing the cause and did not mount a long term promotion on how to prevent SIDS with the mattress-wrapping method.  The two TV programs that were aired, instilled lots of fear into parents, by sharing that where they were sleeping their babies was "unsafe".  There were 60,000 worried callers in the 24 hours after the first show. (1)

In actuality, and it is still known today that even without mattress-wrapping, the baby's bassinet, playpen and crib are the safest place for them to sleep compared to other places in the home. (2)

The UK governmental agencies that did the follow up research on the Toxic Gas Theory cause of SIDS, appeared to be more interested in keeping babies in their cribs, bassinets and playpens than finding the cause of why SIDS was happening.

So the UK research was not completely thorough and did not collaborate fully with Mr. Richardson, the original researcher with his "pet theory", as it was described in the editorial section of the same Lancet journal where they published their follow up findings. (3)

The Richardson Hypothesis, as it was known then, was reported in 1995 in The Lancet to be "unsupported" by the agency's findings. (4)  Yet Dr. Sprott described in his 1996 book "The Cot Death Cover-Up?" (5) the multiple errors committed in their research for that December Lancet article.

We consider the UK agency's greatest error was to sterilize the mattress samples prior to testing them to find if his samples contained the same fungus Mr. Richardson had found on them. They also sterilized their own samples as well. (4)

What then is the Toxic Gas Theory of SIDS?

It means that SIDS can likely occur if all three of these exist together:

 1.  the elements phosphorous (P), arsenic (As), and/or antimony (Sb) are present in the baby’s mattress;

 2.  the common household fungus is present and

 3.  then also that there is an increase in temperature, that is, from body heat or other heat sources.

These simultaneous conditions cause the fungus to grow, metabolizing compounds containing these elements, to create nerve gases, that stop the baby's respiratory and cardiac function, to make SIDS occur.

Mattress-wrapping requires eliminating as many of all the factors involved with SIDS as possible.

Especially important for prevention is keeping the chemical elements P, As and Sb, in mattresses and bedding, away from your baby and minimizing sources of body heat.

Sleep your baby in a wrapped: bassinet, co-sleeper, Pack ‘N Play (or other playpen) or crib. Never sleep your baby on a sofa, couch or recliner.

The standard SIDS precautions still are valid and apply to preventing SIDS. You must sleep your baby Alone, on their Back and in a Crib, in a sleeping situation designed specifically for babies but just that it is wrapped with a BabeSafe® mattress cover.  Use a firm mattress and no soft bedding.

The key to mattress-wrapping is to use a BabeSafe® mattress cover over your baby’s mattress and only 100% pure cotton bedding, with no padding or quilting.

Purpose for a 501c(3) Nonprofit:

A. To share how the Richardson Hypothesis, (the Toxic Gas Theory), explains the accumulated truths about SIDS that have become known to present-day SIDS researchers.

B. To perform chemical, microbiological and toxicological research to verify that the toxic gases are present in baby mattresses.

Email us from Contact Us below, to get a referral for a BabeSafe® mattress cover for your baby's specific sleeping situation.

When I am reading the SIDS research literature, I am surprised to find how many of the facts written there about SIDS, that appear seemingly random, are answered when taken in light of the Toxic Gas Theory of SIDS.

About Us

Barb Knoll, CNM ret.


I am a Certified Nurse Midwife with 43 years in Nursing of which 24 have been in Midwifery. Having delivered over 1,800 babies, I know the desire of every parent to protect their infants. Those who know what SIDS is (Sudden Infant Death Syndrome — also known as Cot Death in New Zealand) it leaves much fear in their hearts as they put their babies down to sleep.

Many mothers have told me their loss of sleep during the first few months after delivery was more due to their frequent checking to see if the baby was still breathing, rather than the baby crying and waking them up. I am convinced that mattress-wrapping with the BabeSafe® mattress covers protects babies from SIDS.

In the course of my practice I have seen the sad deaths of babies who were sleeping on unwrapped mattresses; yet in New Zealand there have been no reported SIDS deaths among the more than 245,000+ babies who have slept on mattresses wrapped with BabeSafe® mattress covers and using the specified bedding for a wrapped mattress, 100% cotton with no padding.

I became a BabeSafe distributor in December of 2002 after the son of one of our L&D nurses died of SIDS. Patrick was 6½ months old. He was in daycare when it happened, and it devastated everyone involved. I found an article about the work of Dr. Sprott in New Zealand shortly after this happened and the rest is history. The effectiveness of the covers impressed me. A photo of Patrick is on our Donations page and sketched in our logo.

In 2004 we started online with Baby Mattress Covers. In 2008 we incorporated into Baby Mattress Covers, LLC.  From November 2018 to February 2019 we took a Sabbatical from selling the covers.  It was then that we decided to do USA research on the mattress-wrapping method.  We no longer have any financial relationship to the sale of BabeSafe® mattress covers. We can still refer you though to where you can get a cover.

One thing that you need to know about my husband Paul is that he is extremely dedicated to whatever he commits himself to. He graduated from Hope College in Holland, MI with a double major in German and Chemistry. He held different jobs for a while but settled in at an analytical food testing laboratory for 7 years. Because he wanted to improve himself in the field of Chemistry, he went to graduate school at the age of 48 and got his Masters in Chemistry. His focus areas were Toxicology, Organic Chemistry and Analytical Chemistry, at Western Michigan University. He wrote his thesis on DNA mutations, smoking and bladder cancer. He belongs to the Honor Society of Phi Kappa Phi.

Paul took over our infant BabeSafe® mattress cover business as Volunteer Manager about 6 years ago. Up until then he was helping me with the website and keeping things straight. In January 2013 he took over the entire running of the business.

I look forward to how Paul will continue supporting the mattress-wrapping through this website and with SIDS prevention research by the future formation of a scientific 501c3 nonprofit.
