When it comes to spring mattresses, there’s a common misconception that all beds with springs inside them contain essentially the same types of springs in similar arrangements. This, however, could not be further from the truth, and pocketed coil mattresses most certainly feel nothing at all like innerspring mattresses.
Pocketed Coils vs. Innerspring: The Difference in a Nutshell
As we covered in our previous article on innerspring mattresses (which we recommend reading as a precursor to this blog on pocketed coils), innerspring beds contain a singular assembly of web-like interconnecting springs. While there is some variation in the types of innerspring technologies on today’s market, pocketed coils are drastically different in that they create a completely independent suspension system where no one spring is physically tied to (or impacted by) any other.
Who Invented the Pocketed Coil Mattress?
British-born inventor James Marshall invented what he called the Marshall coil in 1899, and the Marshall Mattress Company still continues to operate in the Canadian market to this very day. The name pocketed coil came about as result of the fabric encasement Marshall conceived to wrap each individual coil inside. This not only prevented any one coil from getting entangled with adjacent coils, but it also prevented the squeaking sound inherent to lower quality innerspring assemblies.
Pocketed coils provide a wide range of benefits that continue to make them popular with a growing number of mattress shoppers. As compared to innerspring, encased coils isolate motion transfer from one area of the bed to another. Married couples find this benefit especially helpful, since one partner can wake up to use the bathroom during the night without disturbing the other. Another significant advantage of pocketed coils is their unique ability to conform to the natural curvature of your body as you sleep. Whereas innersprings tend to provide support that’s less adaptive to pressure points, encased coils (i.e., pocketed coils) compress more in areas like your hips, while remaining tall and supportive in the crucial lower back area.
What to Look For
While most manufacturers of pocketed coil mattresses will rave about their 600-700 individually wrapped coils, this is standard for any pocketed coil queen-size bed. Even more important than the number of coils is the particular quality of each individual coil’s construction.
Sherwood Bedding’s line of Lumina® luxury mattresses is comprised of all heavy-gauge tempered steel coils that provide greater support and last longer than the vast majority of other coils on the market. Our quality pocketed coil mattresses also incorporate a unique 6-sided foam encasement construction that improve the mattress’ overall stability and expand its usable sleep surface by 14%.
For many of our customers, the startling difference between the feel of a Lumina® and a competitor’s pocketed coil mattress is just as drastic as comparing a standard innerspring with a pocketed coil design. If you haven’t yet had the chance to experience the Lumina® luxury/value combination for yourself, we invite you to visit a retailer near you to see what you’ve been missing.
