1″ Cool Action™ Memory Foam
To give the HB300S a cool feel, Serta tops the model with a full inch of Cool Action™ Memory Foam. This memory foam is cool to the touch, and infused with gel that offers a fine layer of microsupport to your body. This layer of foam has been shown to reduce pressure points, leaving you feeling rested and pain-free in the morning. Cool Action™ Memory Foam is also prized for its ability to cradle the body without leaving dips or divots in the surface of the mattress. Because gel foam springs back more quickly than traditional foams, your mattress will feel new every time you roll over in bed.
1″ Serta® PillowSoft™ Foam
Underneath the layer of Cool Action™ Memory Foam lies a layer of Serta’s prized Pillowsoft™ Foam. This foam is crucial because it provides an ultra-soft layer of support that behaves like normal foam, making your memory foam mattress more receptive to position changes.
1″ EverFeel® Triple Effects™ Gel Memory Foam
One of the newest foams created by Serta, the HB300S is designed with a full inch of EverFeel® Triple Effects™ Gel Memory Foam. This incredible new foam is infused with millions of gel microbeads that react to your body weight and temperature to keep you more comfortable. Because they retain heat and flex slightly, they provide an unparalleled level of support, comfort, and temperature stability while you sleep. This gel foam layer is also supportive, helping you to relieve pressure points and sleep comfortably.
The HB300S is designed with the SmartSupport™ system, a triple-threat system that combines the comfort of EverFeel® Triple Effects™ Gel Memory Foam with the new SmartSupport™ Memory Coil System. This means that the HB300S responds with the comfortable cradling effect of memory foam, while feeling springy and reactive. The SmartSupport™ system is a truly innovative design, and you have to feel it to believe it.
1008 Duet® Coil Individually Wrapped Coil Support System
If you were to remove the fabric covers from older, squeaky mattresses, you would like discover a network of springs that were all wired to the same frame. Originally designed to improve stability, this flawed design meant that movements from one side of the bed transferred across the entire sleeping surface. To ward off this issue, Serta uses the 1008 Duet® Coil Individually Wrapped Coil Support System in the HB300S. Each coil is individually wrapped in fabric that limits noise transfer, and each coil operates independently to further reduce motions transfer—improving your sleep.
BestEdge® Foam Encasement
Do you ever feel like you are going to roll off of your bed because of the lack of support near the edges? To help people to avoid this problem, Serta offers BestEdge® Foam Encasement in the HB300S mattress model. This foam encasement offers a thick layer of support near the edge of the mattress, which actually increases the useable sleeping area of the bed. In fact, research has found that this new technology can increase the useable sleeping surface by as much as 20% over traditional mattress construction. With BestEdge® Foam Encasement, you might be able to continue to enjoy your Queen-sized bed frame, even if you once vowed that your next mattress would be a King. Foam encasement also helps to increase the lifespan of mattresses, since users can spread out and use a larger percentage of the bed. Instead of sleeping in the same spot night after night, users can take advantage of the full width of the mattress.
