EverFeel® Triple Effects™ Gel Memory Foam
To make your sleeping experience as comfortable as possible, the Philosopher Extra Firm contains an inch of EverFeel® Triple Effects™ Gel Memory Foam. This innovative foam is infused with millions upon millions of gel microbeads, which work to wick away heat while simultaneously flexing when they are warmed up. The result is a soft cushion that feels warm, conforms to your body contours, and remains supportive. EverFeel® Triple Effects™ Gel Memory Foam can also help you to regulate your body temperature, since it is a breathable material, unlike some other types of memory foams. This feature makes it perfect for people who tend to get too warm or too cool while they sleep.
Serta® Support Foam
Serta® Support Foam is designed to be incredibly supportive, without being too hard or too soft. The core of the Philosopher Extra firm is two inches of supportive foam, gently hugging your curves without clinging to your body. Serta uses a sturdy 5 lb. foam, creating the perfect surface for sleepers who prefer a firmer sleeping area.
Serta® PillowSoft™ Foam
To gently cushion the mattress, Serta also incorporates a thin layer of their Serta® PillowSoft™ Foam, a plush material that reduces pressure points without feeling overly soft. Also, because the PillowSoft™ Foam is placed underneath the other layers, you won’t even notice this ultra-plush layer, but it will make your mattress feel slightly more reactive—without compromising your support system.
1008 Duet® Coil Individually Wrapped Coil Support System
In the olden days, box springs and inner spring coil systems were all wired to a single frame, which caused problems for couples. When coil systems are intermingled, motion and noise can transfer throughout the mattress. This means that a single movement from your partner could wake you up out of a sound sleep. To combat this common issue, the Philosopher Extra Firm incorporates a 1008 Duet® Coil Individually Wrapped Coil Support System. Each coil is individually wrapped and operates completely independently, eliminating sound transfer and vibrations while you sleep.
BestEdge® Foam Encasement
To top it off, the Philosopher Extra Firm contains BestEdge® Foam Encasement, which means that the outer perimeter is reinforced with solid foam. This feature makes it possible to sleep right up against the outer edges of your bed without feeling like you are going to fall off. BestEdge® Foam Encasement also makes it easier to do things like sit on the edge of your bed and stand back up without any problems. Edge reinforcement has even been shown to increase the useable surface area of your mattress, making your bed seem larger than it really is. In fact, research has shown that with edge reinforcement, your bed can feel as much as 20% larger—which might save you money on a bed upgrade.
Serta is also an industry leader when it comes to using eco-friendly materials, such as soy-based foams and recycled steel. In fact, all Serta mattresses are designed with 95% post-industrial recycled steel, which keeps metal out of landfills. Serta also uses materials that are naturally allergen-free and resistant to flames. In fact, Serta even uses a fire-blocking material inside of their mattresses that can help to limit the spread of flames if a fire ever broke out in your home. With a Serta mattress, you might be able to worry less about incidents, allergies, and potentially harmful materials.
