Hi mike7,
I think that the best reply to this is in post #5 here.
I certainly have biases but it’s towards quality, value, and service, and accurate and meaningful information wherever I see it whether they are a member or not. Membership here is by invitation only and is not open to any retailer or manufacturer who asks. The “value” of any mattress purchase is self evident if you follow the information here and learn “how” to choose (which is the goal of the site) and has nothing to do with membership. There is a big difference between factual information, marketing information, and opinion.
When a reputable manufacturer says something that puts them at risk of a return based on your own perceptions … it’s in their own self interest to give you information that is as accurate as possible or they would lose money. You can read more about “matching” one mattress to another in post #9 here. What they mean is that the mattress they would suggest would be a close approximation or “equivalent” for most people. They are familiar with the “feel” of both mattresses since they carry them both which is why I suggested you call and talk to them (not email).
It means their cover is made from bamboo fiber quilted with wool instead of being a stretch knit with no wool (which would require a fire barrier other than wool). You can read more about the different types of fabrics (including some of the viscose/rayon types of fabrics such as bamboo) in post #7 here. You can read more about the pros and cons of wool quilting in post #6 here.
