Foam Verses Springs
The Materials
A foam mattress is only as good as the foam its made from. There are hundreds
of different grades of foam. We use only those which will make an outstanding
mattress. Foam molds to the body.
The quality of springs is determined by their length. The longer the spring the
more coils its possible to use. The more coils you have, the better the spring.
Springs have diameters measured in inches. They cannot mold themselves to the
body.
The Difference
Manufacturing inner spring sofa bed mattresses begins with a problem. The mattress
can be no thicker than about 4". Therefore the springs can be no longer than
4 inches. Standard mattress springs are at least 9" long. A 4"
spring simply cannot support a person well. That means (among other things) the
sleeper will feel the bar of the sofa bed.

Differences between our two models
We offer two different quality levels.
Gold or Platinum
Our Gold ( Foam Density:
1.8 lbs per cubic foot ) keeps the cost to a minimum.
Our Platinum quality mattress (
Foam Density – 2.5 lbs per cubic foot )
goes all out. It is the perfect choice for the for heavyweight sleeper.
Both are superior mattresses.
Higher densities do not mean firmer, they feel pretty
much the same.
WE INVITE YOU TO USE THESE FOAM DENSITIES TO COMARE MATTRESSES
_________
A consideration when choosing, is the weight of the sleeper.
Most sleepers will find the Gold
quality an excellent choice.
Heavyweight sleepers will compress the mattress
beyond its ability to cushion the bar.
The denser foam of the Platinum
mattress will be more comfortable.
Denser Foam does not mean harder.

Specifications For Our Gold Model -
available in full and queen sizes
- Foam density – 1.8 - 1.9 lbs per cubic foot ( high density)
- IFD (indentation force deflection)– 48 - 50lbs ( high compression)
- Foam thickness - 4 inches.
Specifications For Our Platinum Model
- available –full and queen
- Density – 2.5 lbs per cubic foot ( high density )
- IFD (indentation force deflection) – 41 lbs ( high compression )
- Foam thickness - 4 inches.
What this means
INDENTATION FORCE DEFLECTION
- The Indentation Force Deflection (IFD) number represents the pounds of force
required to indent a foam sample by a specified percentage of its original thickness.
- IDF is the measure of the foams firmness.
DENSITY
- Density is a measurement of the pounds per cubic foot. It is one of the most
important of all form properties. The lower density, the more air spaces there
are in the foam.
- High density foam products generally offer a great deal of support.
What this means to you
HOW DENSITY AND IFD AFFECT FOAM PERFORMANCE
- High density foams can be made very soft.
Low density foams can be made very firm.
There is no such thing as a "hard" or "soft" density.
- There is a difference between firmness and support.
IFD is a measurement the support of the foam.
Support is the foam's ability to "push back" against weight and prevent
the foam from "bottoming out."
Higher density foam helps prevent the feeling of having the foam collapse beneath
the body weight.
OTHER FACTORS
-
Foam durability, flex fatigue and compression set are other terms related foam
performance. We concern ourselves with all of these factors and more.
-
There are books written about the physics and chemistry of foam. For more information
we refer you to the "Polyurethane Foam Association".
- Their web address is www.pfa.org
The number one question asked of us is:
" Will I feel the bar ? "
The answer is: "Not likely". There are some exceptions.
-
The issue is the density of the mattress foam. The denser
the foam, the more forgiving the mattress. If you think it might be a problem,
we urge you to consider our platinum
grade.
- No other sofa bed mattress can beat our quality in an any respect. As regards
feeling the bar, our products excel.
