Tobia Gemma Thermal Comfort Firm
Spaldin Sleep Systems introduced the
Gemma Thermal Comfort line of
Tobia Natural Sleep foam
mattresses in 2013. These mattresses feature
Gemma foam, a newly developed form of cell structure for cushioning foams.
Gemma has its own website,
http://www.gemmasleep.com/en/, where
Spaldin explains
Gemma foam and
Thermal Comfort. The website's banner says, "GEMMA™ / sleep + science / TOBIA® Technology inside."
What is Gemma?
On the
Gemma is a
video showing what
Gemma foam is, how it is made and how it works. According to
Spaldin,
Gemma is "a revolutionary technology designed to expel the moisture and heat produced by our body while sleeping." This technology was developed by
Industrias Tobia, the parent company of
Spaldin Sleep Systems, described as "a high-tech European bedding manufacturer pioneer in the Natural Sleep concept that combines the use of Fully Certified human and ecologically safe materials with the maximization of Thermal Comfort and Ergonomics."
The key feature of
Gemma is its "gem-like" crystaline structure of open dodecahedrons (a
dodecahedron is a 12-faced 3-D figure with pentagonal faces). This lacey design allows not only air, but also moisture to pass through. This is to keep the top surface both cool and dry. With both air and moisture circulating, the moisture evaporates, further cooling the mattress.
This design was inspired by natural structures, such as honeycomb cells. According to the video, the foam is formed in two stages. In the second expanded into the open crystaline configuration, which is highly permeable.
What is Thermal Comfort?
Spaldin explains
Thermal Comfort this way: "Thermal comfort is measured by the capability of a mattress to allow this natural heat dissipating mechanism to work and to stay dry."
They go on to explain the role of cooling, how the body sleeps better when the temperature is lowered, such as through perspiration. But this means is halted during the REM (Rapid Eye Movement) cycles, and sleep is interrupted if the sleeper becomes to warm.
The
Gemma page also describes four "Mechanisms of heat elimination" ( [1] Radiation, [2] Conduction, [3] Convection, and [4] Evaporation) and how they operate when sleeping on a mattress.
Models
So far
Spaldin has two
Gemma models:
Gemma Thermal Comfort Firm and
Gemma Thermal Comfort Plush. The difference between these two models is in density of the top layer of plush foam. This foam in the
Gemma Firm is 2 pounds, while that of the
Gemma Plush is 1.3 pounds. Otherwise, the descriptions of the two
Gemma models are the same.
The
Tobia Gemma Thermal Comfort Firm Mattress has a
cover of organic
cotton with fire-resistant
Visil silica-viscose fibers.
Under the cover are two layers of comfort foam. The top layer is 2-lb. density soft cushioning
foam. The second layer is
Spaldin's 3.2-lb.
Gemma memory foam. Each of these foam has the
Gemma gem-like structure. This takes the place of reticulated foam for allowing moisture to flow through for rapid drying.
The support core of the
Tobia Gemma Thermal Comfort Firm is a layer of 2-lb.
polyurethane foam. This and the other foams used in
Spaldin mattresses contains uo to 60% plant-derived polyol oils, reducing dependency on petroleum products.
The
Gemma Thermal Comfort models are suitable with
platform beds and
slatted (European-style) foundations. They are also compatible with
adjustable beds. The
Gemma models are available through several retailers. They are covered by
Spaldin Sleep Systems' 20-year warranty.
