Joyce, your comments about synthetic latex are not necessarily accurate. Mountain Top makes a 100 percent synthetic latex which just received Level 1 Oeko Tex certification. As for using this forum as a way to post your store information and phone number is a bit spammy, wouldn't you agree?

There are many good brands of 100% all natural latex rubber. Mountain Top also makes 100% all natural latex rubber (see attached letter). Level 1 Oeko Tex certification is the most stringent criteria, as it is a product classification for babies and infants because their skin is most sensitive. "Safety first" is the credo for the little ones.

If the attached letter does not come through, please contact me and I will be happy to send it to you in an email (my phone number is listed on my profile).

Thanks Joyce, but Nest Bedding is one of your competitors just a mile or so down the street. We are the only 5 star mattress store in the East Bay on Yelp. Yes, the customer comes first. They asked for a comparison, not a place to buy a mattress in Berkeley. As a forum, we professionals should resist the temptation to self-promote and just be a resource. That keeps it a valuable forum. Stop by sometime and we will show you the benefits of Nest Bedding Mattresses. We don't carry Savvy Rest.

And their 100% synthetic latex is also level 1 Oeko Tex certified safe for the little ones too. Above you made it sound like all synthetic latex has toxic chemical off-gassing, which is not factual.

Nest Bedding is not a competitor down the road as Mountain Air Organic Beds does not have a presence in California. We are located in Fayetteville, Arkansas.

If I was the consumer that is the one I would buy the Sterling organic mattress from Nest Bedding if you are comparing to PBL. The construction is good, latex from LatexCo if they choose 100% all natural is customizable with a zipper casing and uses organic cotton and wool in the casing. I love wool, sleeps cool in the summer, cozy in the winter and helps regulate body temperature all night long. It is dust mite resistant, not enough cotton or wool to create body impressions.

Good Luck!

Frankly, you are wrong. You obviously know little about Nest Bedding mattresses. They are constructed of organic wool, organic cotton, zoned pure latex which is Oeko Tex Certified and built on a base of Leggett and Platt zoned pocketed coils. Which Simmons model uses these elements? None. PLB has organic cotton covers and organic wool for the fire barrier? No.

Adding cotton and wool provides a breeding ground for dust mites. I went to the website and saw that the mattresses asked about were individually pocketed coil systems topped with latex. Cotton and will compress easily, leaving permanent body impressions. It's just a mattress with its own set of problems.

Peter, as a 15 year veteran of the industry, mattress company owner and designer, I know a thing or two about mattresses. I would highly recommend reading up on dust mites. Dust mites are an arachnid, and they require food and water. Cotton and wool are NOT a breeding ground for dust mites, its actually the the opposite. Wool and cotton are breathable, drying out quickly, more quickly than synthetic fabrics, thus not providing food and water they need. Its a common misunderstanding. Also the cotton is the cover, not the fill. Its on the website. Wool is tensile strength stronger than steel.
