Essentials Prestbury Firm

The Prestbury Firm is one of two middle models in the Essentials Collection of Perfect Sleeper innerspring mattresses by Serta. It is about 12" high with three comfort layers between the quilted cover and the Continuous Support innerspring unit. The stated goal of the materials and configuration of the Perfect Sleeper Essentials Prestbury Firm mattresses is undisturbed sleep.

The heart of the Prestbury Firm is the 520 coil count Continuous Support Innerspring. The rows of 13.75 gauge continuous coil springs run lengthwise (head-to-toe). This minimizes motion transfer from one side to the other to reduce partner disturbance. Continuous coils generally have a longer usable life than most other innerspring types.

Closely associated with the Continuous Support innerspring is Serta's Comfort Last Construction with the Reinforced Edge system. The key item is the 6-gauge border rod, seen at the top and bottom in the picture of the innerspring. This edge support prevents roll-off, enables the user to sit on the edge, and is intended to stop sagging.

The blended-fabric top panel (polyester, rayon and lycra) of the cover of the Essentials Prestbury Firm is quilted to Serta's Pillo-Fill, FireBlocker flame-retardant fiber, and an inch of Serta's PillowSoft Foam. Pillo-Fill is breathable quilting fiber. It promotes airflow and it wicks moisture away from the surface. PillowSoft is a very soft foam, used here to make the quilt cushiony.

The comfort layers consist of Cool Twist Gel Memory Foam, 1" each of Serta's PillowSoft Foam and Support Foam, and a Serta Insulator Pad.

Cool Twist is memory foam infused with liquid gel. The structure of this foam is designed for airflow. Memory foam, developed from materials designed to cushion NASA astronauts at launch, conforms to body contours to relieve pressure points. The gel is for temperature balance. The original memory foam tended to accumulate heat, so manufacturers are using means to make it cooler, and one of them is gel, which conducts heat away from the surface. It also can absorb more heat than memory foam before becoming warmer.

While PillowSoft, which is also in the quilt, moderates the natural firmness of the continuous coil innerspring, Serta's Support Foam ensures overall firmness for consistent cushioning support of the sleepers. The Insulator Pad transitions support from the innerspring to the foam layers. This is to prolong the usable life of the foams.

Being an innerspring mattress, especially one with continuous coils, the Essentials Prestbury Firm is compatible with box springs, platforms, and adjustable beds. The foundations Serta supplies for this model are its StabL Base double-beamed foundation with V-shaped construction, and the Motion Perfect II Adjustable Power Base.

The Prestbury Firm is covered by Serta's 10-year limited warranty. It is available through several retailers. Some retailers have alternative names for this model, such as Warren Firm.
