The pocketed coil is one of the greatest innovations in sleep history. The individually pocketed coils were first introduced in the early 1900’s and have since been perfected into what we find in a majority of mattresses today. This same spring system, sometimes with slight variations, is also commonly know as individually pocketed coils, individually wrapped coils, encased coils, or Marshall coils. Each coil is separately wrapped in a fabric pocket. The separation in coils is the main difference when compared to any other spring system. This brilliant concept allows for these two main significant benefits:
Doctor Recommended, Contouring Support
The individually pocketed coils immediately respond to varying pressure and weight applied by the different parts of your body. Whereas a more traditional spring system is connected all throughout with a continuous wire. When pressure and weight are applied to a specific area of a traditional innerspring, this continuous wire causes tension and transfers pressure to the surrounding coils, causing a lack of support. Since the pocketed coils each work individually without disturbing the surrounding coils, they provide orthopedic support by conforming to the contours of your body.
Motion Isolation for an Undisturbed, Restful Sleep
The individually wrapped coils aren’t just your doctor’s top pick, they’re also an ideal choice for couples. The pocketed coils drastically reduce the transfer of motion from one side of the mattress to another. Sounds like a bunch of mattress “mumbo, jumbo,” but what does this mean to you? Well, if your partner is restless some nights, climbs into bed after you, gets out of bed before you, or just can’t seem to find their comfort zone, your sleep won’t be disturbed. Since the pocketed coils move individualy, movement on one side of the mattress won’t cause movement on the other. A mattress with individually pocketed coils, at the same time, will help eliminate these possibilites to begin with, doubling your results!
Pocketed coils are used in a large majority of our modern day mattresses. Commonly found in hybrid mattresses, the individually wrapped coils are usually topped off with varying combinations of comfort materials like standard support foam, memory foam, latex, and/or gel. On their own, these materials each play a significant role within the mattress. Combined, they are more effective and said to be more durable. Some mattress experts feel that a hybrid mattress will be less prone to taking body impressions because the construction materials work in unison to support each other unlike any other mattress construction type. Although keeping the same core concept design, advancements are still being made to the pocketed coils. These advanced coil innersprings are often found in higher-end mattress models. Serta’s duet pocketed coils are found in their iSeries Hybrid collection, featuring 2 coils within each pocket. This coil within coil advanced innerspring design provides extra support and durability. BeautyRest Black has a one-of-a-king triple braided pocketed coil where 3 interwound & braided coils form one ultra-strong and supportive coil. Some higher-end mattresses have micro coils, a layer of micro pocketed coils on top of the pocketed coil innerspring. Owner satisfaction rates rate highly throughout all pocketed coil mattresses. Nevertheless, heavier persons may consider a mattress with an advanced pocketed coil innerspring for improved strength and support.
Coil count refers to the number of individually pocketed coils within a mattress. Most pocketed coil innerspring coil counts range between 450 and 900, 725 being about average. Mattresses with a higher coil count are more expensive than mattresses with a lower coil count, all other things being equal. In most cases, a mattress with a higher coil count provides stronger support, better contouring, and more longevity.
Coil gauge is a measurement of how large the coil wire is in it’s diameter. Mattress coil gauge typically ranges between 12 and 15. The higher the gauge, the thinner the coil wire and the softer, more springy the feel of the mattress. The lower the gauge, the thicker the coil wire and denser, more firm the feel of the mattress. The coil guage and composition of the comfort layers largely determine how soft or firm a mattress will be.
