The primary feature of innerspring mattresses in the Premium Innersprings Collection by Corsicana Bedding is the support unit of reversing offset coils, also called VertiCoils by major mattress components manufacturer Leggett & Platt (also a manufacturer of adjustable beds). This development increased motion isolation in offset coils and decreased roll-together. Most of the reversed offset coils in Corsicana Premium Innersprings models are called VertiCoils, revealing the supplier of this key component.
The coil counts of Premium Innersprings Collection models are either 390 or 460 in Queen-size mattresses. According to Corsicana, smaller diameters allow greater coil density and smoother support.
Unspoken in descriptions of this collection and its constituent models is the balance between density and coil wire gauge. Smaller diameter coils require thinner wire (higher gauge number). This makes the coils individually more flexible, more responsive, which means they are potentially less durable. However, with more coils closer together, they share the load more evenly, which increases the lifetime of the coils.
Coil units in Premium Innersprings mattesses are foam encased. This serves as edge support for the surface, making it enitrely usable.
Several model names are found in Corsicana's Premium Innersprings Collection, such as Shelby, Astor, Halstead, Canberra, Wescott, Diana, Eastbrook, Kennedy, Baron, Florence, Woodlands, and others. Some of these may really be models from earlier collections now rolled into this one with the realignment of Corsicana's lineup. Also, licensing arrangements and retailers' preferences determine model names, so two models with different names at different retailers may be essentially the same model.
Most Premium Innersprings models have tack-and-jump quilted covers. The quilting includes quilting foams and fibers (such as polyester fill fibers). Fire resistance relies on special fibers. Most mattresses' model descriptions found on retailer sites do not specify the cover fabric, but those that do name cotton. Some of them list the quilting as either 1½" or 2" thick.
Mattress heights are not always listed, but those that are range from 9½ to 13" high. This does not exclude some which may be higher or lower. Since the innersprings are uniform in height, the overall height is mostly determined by the comfort layers—such as support foam, comfort foam, and memory foam—which also determine the firmness level, which ranges from very firm to plush.
Warranties on mattresses in the Premium Innersprings Collection vary by model. These are usually either 5 or 10 years. Sleep trial periods depend on retailers. These models are carried by many regional and local outlets across the country.
