A pocket coil is known by many names: pocket spring, wrapped coils, encased springs, or Marshall coils. Pocket coil mattresses are the most popular type of innerspring mattress available.
More often than not, you’re going to see two types of mattress springs on the market: pocket-coil and innerspring. But what do these two words mean? And how do you know which one is better for your “Zzz time”?
A traditional innerspring mattress, or open coil, has a network of metal coils that are all connected. This means that when pressure is applied, the springs all react together. This transfers motion, so if your partner moves you’ll feel it.
Additionally, because the coils all move together, traditional innerspring mattresses provide less comfort and don’t spring back as easily. They also don’t contour around your body as much as a pocket coil mattress.
Pocket coils, on the other hand, are not connected and act on their own. This means that if you apply pressure to a pocket sprung or coil sprung mattress, only the coils being pressed down will react, whereas on an innerspring mattress all of the surrounding coils will compress.
This approach allows the individual pocket coil mattress to contour to your body better and doesn’t transfer motion as much as a traditional innerspring mattress. This technology could save your relationship one day.
the pocket coil mattress may be the most popular innerspring mattress, but it has a fierce competitor in the foam mattress. Ultimately, the right mattress for you comes down to personal preference.
you don't pay very much more for a pocketed coil bed than you do for a regular innerspring. While the final cost of even the best coil spring mattress might be higher than that of a similar bed with ordinary springs, its durability means years of affordable and comfortable return on your investment.
