and Mattress Selection
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.

The smallest mattress coils so far
It used to be that the shortest mattress coils were the 4" Bonnell coils in a sofabed mattress. The reason they were so short, when most coils were 7 or 8 inches high, was so the mattress could be folded to fit inside the sofa under the seat cushions.
With the introduction of pocket coils, the trend was for innerspring coils, at least the wrapped coils, to become taller, up to 9 or 10 inches. This allowed greater conformabiity and more...
Minicoils or Microcoils?
A previous blog article, Microcoils, covered the use of coils in mattresses that are significantly smaller than innerspring coils. In this article, I noted that some of these smaller coils are much smaller than others, and that there has not been a concensus on terminology.
Until now, the whole category of small springs has been classified as microcoils. But now several manufacturers are placing two layers of these coils above the support core of a mattress....

They were invented in 1900 by James Marshall, an Englishman who migrated to Canada. In Toronto, Ontario, Canada he founded the Marshall Mattress Company to make mattresses using his technology. The company is...

It is common knowledge that we need sleep, and that—for the most part—several factors determine whether and how we sleep. Among these factors are time of day, how tired we are, physical condition, medication, diet, amount of light, noise, vibration and motion, warmth and cold, pain and comfort.
Even knowing this much, it is easy for many people to...

Microcoils (or minicoils) are coils which are smaller than standard innerspring coils. Innersprings are usually 6” to 8” high. Some microcoils are 4” high, but most are much shorter, usually 1” to 2½” high. They are also narrower and made with lighter gauge wire. Some microcoils are only ¾” tall. At least one supplier calls the shorter ones...
