This year (2016) is the Silver Anniversary of memory foam mattresses. It was 25 years ago that Fagerdala World Foam put the Swedish Tempur Mattress on the market in Sweden. The popularity of this led the company to start selling memory foam mattresses in the United States, and Tempur-Pedic was established in Lexington, Kentucky.
Since then, memory foam has changed the way mattresses are made. Memory foam mattresses quickly surpassed waterbed sales. It took longer to match innerspring...
Protecting Your Mattress and Yourself
So you are buying or have just bought a new mattress. The sales person at the store, customer service rep on the phone, or the website selling the mattress recommends buying a mattress protector, too. "Why," you ask, "do I need a mattress protector?"
Good question. Why or why not? We don't like the idea. For one thing, it's one more thing to buy. For another thing, we may remember the uncomfortable plastic sheets our parents put on mattresses when we...

through Pressure Mapping
Pressure mapping is not exactly new to the bedding industry. It has been used to test mattresses at least since 2012, when Scott Braddam used it to evaluate mattresses on Beds.org, for example in his review of the Select Comfort Sleep Number Classic Series. By 2013, Kingsdown was using it in matching a customer with the right mattress.

Silica and Sleep
A popular song recorded in 1954¹ begins with, "Mr. Sandman, bring me a dream." An old nursery rhyme says, "The Sandman's coming in his train of cars / With moonbeam windows and with wheels of stars."
Both of these verses are about the mythical Sandman of folklore in Northern Europe. The imaginary Sandman caused people to sleep, then sprinkled magical sand on them to bring good dreams. The "sand" in the stories refers to grainy particles most people have in...
Progressive Rate Springs:
What Are They Doing in My Bed?
If anyone of us knows what progressive rate springs (PRS) are, the first place we expect them is in wheeled vehicles. In fact, that is the intended application of progressive rate coiled springs, and that is what comes up first in an online search. So it surprising to find "progressive rate springs" in the description of a mattress. And a waterbed mattress, no less!
Before we go on, let's see what a progressive rate spring is. Some...
Ubiquitous Vinyl - It Is Everywhere
Vinyl - it is literally everywhere. It covers our houses, carries water into the house and sewage out, and bags our food and our garbage. It is hard; it is soft. It can be the box and the wrapping. We can pour out of it, drink from it, eat off it, and eat with it. It can protect our mattress, and in some cases can be the mattress. And it can be the casing on our remote.
So what is vinyl? And how can it be used for so many things?
When we say...
Sleeping on Air
Many of us have dreamed at one time or another of floating on a cloud. Sometimes using a high-end luxury mattress is described as "sleeping on a cloud" or "sleeping on air." That is not always just a figure of speech. When we use an airbed, we are literally sleeping on air. As with any mattress concept, the goal is restful, restorative sleep.
The modern airbed had its beginning with bicycles and automobiles. The first pneumatic tires (inflated with air) used...
What Are Performance Fabrics?
John is looking for a lightweight jacket, one to keep him dry and cool on a rainy summer day. He finds a Windbreaker online "with performance fabrics."
"Huh?" he thinks, "What's that?"
Mary needs another jogging outfit. She wants to stay cool and dry, not soggy and itchy as in the old running clothes. Aha! Here on Amazon is a top-and-shorts combo made of "high level performance fabric."
"Okay," she mutters, "They're throwing all these new-fangled terms at...
