BIA Mattresses's Hospitality Series has three hotel/motel models, all innerspring mattresses. The other three models in this series are are more suited for institutional use. The three industrial/commercial models are Hotel/Motel Good, Hotel/Motel Better, and Hotel/Motel Pillow-Top Best.
Two-sided construction is standard for hotel and motel mattresses by BIA Mattresses (BIAM), the namesake brand of Bedding Industries of America (BIA). That feature makes them more durable, hence more economical, for the hospitality industry.
While they may share other features, these three models are distinct in a fundamental way. The coil type in each differs from the other two. The Pillow-top Best model has pocket coils. Better has continuous coils, and Good has Bonnell coils. The coil counts are 700, 419 and 390 respectively.
The pocket coils in the Hotel/Motel Pillow-Top Best (otherwise known as encased coils, wrapped coils and Marshall coils) are not tied to each other, neither at the top, nor in the middle, nor at the bottom. This is why they are in fabric pockets. It is the pockets that keep the coils separate while keeping them together.
The encasings prevent one coil from meshing with its neighbors. This allows each coil to respond independently of those next to it. The result is evenly distributed support. The smaller portions of the body, such as the lumbar, are supported because their coils are not pulled down. The larger portions, such as the hips, don't bear all the load, so they do not have excess pressure. Independent response also means no transfer of motion from one sleeping partner to the other.
The pockets are attached to each other, so they keep the coils where they belong in the array. This maintains innerspring integrity. This innerspring has five zones of heavier and lighter coils, with firmer coils under the heaviest parts of the body.
With continuous coils, as in the Hotel/Motel Better mattress, all the coils in one row are formed by one strand of wire. The strands run head-to-toe, so this minimizes motion transfer. Continuous coils are generally the least conforming coil type. But they are also the most durable, often lasting more than 20 years.
Bonnell coils, the ones in the Hotel/Motel Good mattress, are the oldest mattress coils. They were developed from buggy seat coil springs in the early 20th Century. Helical wires run the length of each row, tying one row to the next and the coils in a row to each other. The coils are more-or-less hourglass in shape. This lets them respond to a little weight, but stiffening up part-way down to hold more weight. These are the least expensive coils to make and assemble. Durability depends on the coil gauge and how close the shape is to being cylindrical. The heavier the gauge (lower number) and/or the more cylindrical the shape, the more durable they are.
Bonnell and continuous coils have perimeter rods around the top and bottom of the coil unit. This maintains innerspring integrity and provides edge support to the sleeping surface. In a pocket coil mattress, this role is usually fulfilled by foam encasement.
Each Hotel/Motel Series model has a heavy-duty insulator pad on either side of the innerspring unit (remember, these are 2-sided). This keeps the foam padding out of the coils and the coils out of the foam. It also transitions support from the firmest (coils) to the less firm foam.
Next out from the insulator pads is a polyurethane foam comfort layer (BIA calls it a "topper") on each side. The height of this layer in each model is enough in the Good and Better to bring them to essentially the same thickness, about 8" high, even with their different coils. In the Pillow-Top Best, the height, exclusive of the two pillow tops, is about an inch higher.
The Best adds another layer pair, the pillow top (aka pillow innertopper) of poly foam on each side. This adds approximately 2" to each side, making the mattress about 14" high. The pillow top makes a mattress plusher, especially at the edges. Since the edge of the main body is supported, this is not enough to cause edge sagging and roll-offs.
All BIA Mattresses Hotel/Motel models are covered with institutional grade damask fabric. This is described as deluxe in the Good, premium in the Better, and imported in the Best. What makes the difference is not described. Judging by the photos, the cover is quilted, but the foams and/or fibers are not named. It is quilted to a flame resistant barrier to meet federal and state flammability standards.
An 8" high upholstery insitutional wood foundation is provided with the mattresses in this series. However, they would work with platform beds and possibly adjustable beds. Box springs, unless the newer advanced design, are questionable for the Pillow-Top Best.
BIAM's Hotel/Motel Series mattresses are coverd by a 10-year non-prorated warranty.
