Coil springs

I finally got bored enough that I decided to spend some time boning up on coil springs / innerspring mattresses. Time to learn about Bonnell springs, coil counts, wire gauge, and whatever else is important in the world of innerspring mattresses... This message was modified Sep 20, 2007 by haysdb

Bed Express There are 4 types of innerspring units used in today's mattresses:
Innerspring units are named by the number of coils in a full (or double) size bed. To compare coils, you must know the number of coils in a full size, regardless of the size bed you are actually buying. |
Leggett & Platt

Leggett & Platt (Wikipedia entry) The 124-year-old firm comprises 28 business units, 33,000 employee-partners, and more than 300 facilities located in over 20 countries. 2004: Revenues exceed $5 billion. Company History In 1883 in Carthage, Missouri, far removed from any major metropolitan or urban areas, a historical partnership began. J.P. Leggett, an inventor, initiated the partnership because he had developed an innovative bedspring. Mr. Leggett’s bedspring consisted of single cone spring wire coils, formed and interlaced in a unique manner, then mounted on a wood slat base. The bedspring could then be used as a resilient, durable base for the then-popular cotton, feather or horsehair mattresses. Needing expertise in manufacturing and production, he recruited his brother-in-law, C.B. Platt, whose father owned and operated Platt Plow Works, into the partnership. Together, they perfected the equipment necessary to produce the components of their Leggett & Platt bedspring, which was patented in 1885. Bedspring vs. Innerspring At the time of their invention, bedsprings referred to cone-shaped wire coiled springs, attached to a wooden slat foundation, used to support then-popular mattresses. These mattresses were typically made of horse hair, corn husks, cotton, feathers, or another soft material. Early bedsprings functioned similarly to today's box springs in their support of a mattress. However, box springs are rather rigid in structure, while bedsprings provide a more flexible surface. Innersprings, by contrast, refer to the core system of wire springs that, along with various types of foam and other padding materials, comprise the insides of today's mattress. The mattress is usually coupled with a box spring to create a sleep set. Innersprings can be coiled springs laced together, continuous coil springs, or individually pocketed springs, that support a person sleeping on the mattress. |
Re: Coil springs
Mattresses (Wikipedia entry)Types of coilsThere are four different types of mattress coils:
www.sleepdex.org Offset coils are more expensive than Bonnell or Marshall coil springs but they are designed to hinge for more support and comfort in a mattress. Offset coils conform better to body shape than Bonnell or Marshall coils. Continuous coils are thought to provide the maximum coil strength by working together and gathering strength off of the next coil. Continuous coils work similar to offset coils in that they conform and distribute body weight efficiently and limit the transfer of motion; two qualities that are highly prized in today’s modern mattress. The Do-Not-Remove TagAll mattresses and pillows come adorned with the anxiety producing do-not-remove-under-penalty-of-law tag. This innocuous piece of reinforced paper strikes fear into the hearts of millions of consumers who would love to cut the annoying tag off of their product. Well, consumers unite! Go right on ahead and rip off that tag! There are no pillow police or mattress monitors that will show up at your door, cuffs in hand, ready to cart you off to the tag remover reformatory. The tag was intended to provide important consumer information regarding the compliance of the construction materials with federal use and flammability regulations, the content of the product, as well as to give consumers product care instructions and wearability info. If the tag is removed by the seller, it is certainly a violation of federal law. However, the consumer is welcome to remove the tag at will. The Better Sleep Council - Don't be fooled by their name or their nonprofit status, the Better Sleep Council is the mattress industry and they attempt to get people to buy mattresses. Their website encourages people to throw out old mattresses after 5 to 7 years or even when you find you've had a better night's sleep in another bed. This is probably overkill, although it is a good idea to not continue to sleep on an old dilapidated mattress. Disposing of old mattresses The Salvation Army will take donations of mattresses, but they prefer items that are in decent condition. Don't call them if your old mattress is too dilapidated. The good thing about the Salvation Army is that they will come pick up the mattress, and sometimes you can even leave the mattress outside if you aren't going to be home. Call your local Salvation Army (they are in the phone book) to confirm that they will take mattresses and to schedule a pick up. This message was modified Sep 20, 2007 by haysdb

Here is a picture of a continue coil system NOT made by Leggett & Platt WicklineBedding.com Superlastic is the trade name for the continuous coil system found in Sleep Wickline Mattresses... its was developed in Sweden in cooperation with Rolls Royce. Conventional spring support was not enough for this ultra premium car, so engineers develoed a continuous wire product for greater support and durability. The same quality and support features holds true for the Wickline Innnerspring System.  |

Thanks for a great link BeddyBye Leggett & Platt Innersprings Descriptions of each of Leggett & Platt's innerspring products. LURA-FLEX™ Lura-Flex™ is perhaps the best Offset design spring system available. Each coil flexes independently for more sensitivity to body contours, and more durability with less friction.

How did you get that link into your post??? I tried! I notice L&P has a new coil called Verti-Coil. I wonder how that is compared to the LuraFlex. I love researching this kind of stuff! This message was modified Sep 27, 2007 by a moderator

"Remember: Once you're asleep, every mattress feels the same." LOL! This thread is a good short primer. Here's another guide and it also discusses foundations a little: http://extension.usu.edu/files/publications/factsheet/HI_08.pdf Here's another, more global, perspective: http://www.mattressinside.com/orthopedic.html This message was modified Aug 30, 2010 by TC2334
