A bed usually consists of two parts:
A. A foundation box springs or platform
  They're rarely box springs now but v-shaped steel modules that form a grid.
  See Foundation or Box Spring? | Sleepinglikealog.com
B. A Mattress

Mattresses are generally composed of two main sections
1. A support section on the bottom
2. A comfort section on the Top 
3. A fabric cover (ticking)  The covering over comfort section may have some padding also.
Foundation - A box spring or platform that the whole thing sits on. Usually 8 inches.
There are several types:
  Innerspring - Wire coils or interconnected springs
  Foam (Polyurethane or latex) 
  Adjustable air like the Sleep Number beds
 - Innerspring mattresses traditionally had a quilted batten fabric
     that is frequently synthetic.
 - Foam mattresses usually have one or more layers of a less dense foam on the top.
     They frequently have a memory foam top layer
 - Hybrid mattresses are innersprings mattresses with a foam comfort section
   Air beds have a foam confort layer

types in the general mattress page

Both innerspring and foam mattresses got good scores in the

You can spend $30,000 or more for a mattress.
Kluft luxury beds are hand-stitched after being filled with cotton, Joma wool, and latex. Great for hot sleepers - the unique design lets hot air flow away from the body.

Considerations and features in selecting a mattress

  • Type: Innerspring, foam or adjustable air. /li>
  • Both inner spring and memory foam can have infused gel for cooling.
  • Dual firmness - Different density foams on the left and right (available on kings and queens). Like some at the Natural Mattress Store
  • repositioning the layers to change the firmness like the Natural Mattress Store
  • Inner springs can be either independent coils, so compressing a few has minimal effect on adjacent coils, or interconnected wires.
  • Some foam mattresses can be vacuum compressed in a box that will fit in the back of your car, like the Essentia and KEETSA.
  • Adjustable mattresses with articulating head and foot like The Sealy
  • Traditional innerspring mattresses will not work as well with adjustable mechanism to rais the head and/or feet underneath, because they do not bend as well. Hybrids with smaller springs will be ok.

Some Mattresses Examples:
Prices are for Queen sized beds.
Note: Many manufacturers keep the construction details (e.g Indentation Load Deflection (ILD) values,

Green Mattresses
These are mainly mattress using natural latex foam rather than petroleum based polyurethane foam.

Note: Some people are allergic to latex.

Beware of what some manufacturers call "organic mattresses", they may have some organic cotton, but that's all.

Mattress Firmness -

Back Pain:
Traditional wisdom was that a firm mattress was best for your back. This was when soft mattresses allowed sag so your back was curved. What you want is a mattress which allows you back to rest in a normal position. You want it to avoid sag but to be soft enough for your shoulders and hips to sink in when on your side. New mattresses use things like independent coils, multiple density layering and memory foam to avoid sag and still have form fitting capabilities. A medium firm mattress is usually best.
If you sleep on your side you need a softer mattress to allow your shoulders and hips to sink in. If you sleep on your back (better for people with back problems) a firmer mattress will work.

There are pros and cons to waterbeds. If you lie on your stomach, the water bed allows you to increase the sway or the sag of the back.
Claims that a mattress is "orthopedic" or "medically-approved" should be viewed skeptically. There has not been extensive medical research or controlled clinical trials on the topic of mattresses and low back pain.

Indentation Load Deflection (ILD)

  • Soft 20-24
  • Medium. 25-29 Recommended for those who enjoy a softer feel.
  • Regular firm. 30-34 Recommended for those who like a good firm feel, but not extra firm. Usually recommended for those who weigh less that 150 pounds.
  • Extra firm. 35-39 Recommended for those who like extra firm support.
  • Ultra firm*. 40-44 Recommended only for those who insist that they enjoy sleeping on the floor.
(ILD - Pounds to compress a 4" thick sample to 3" (25%))

Consumer Reports found that most mattresses advertised as firm were actually Medium or Soft.


Coil Spring Mattresses
In Consumer Report tests, a higher coil count or firmer mattress didn't necessairly reduce sagging.

Type of Foam
Latex Foam Rubber and Flexible Polyurethane Foam (FPF) at Polyurethane Foam Association (PFA)
Rubber Facts (Word Doc) at Monmouth Rubber Corp.

Memory Foam:
Memory foam is essentially made from the same chemicals as polyurethane foam, but it has added chemicals to it that change the way it feels.

Foam - All foams are basically open-cell.
Polyurethane foam, latex foam, and PVC foam.

Density - Technically the weight per unit of volume (specific gravity). Density is commonly misused to mean the hardness or softness of a material, specifically in our case, sponge. Many times someone will ask "What is the density of the material?" What they really mean, in most cases, is "What is the hardness or softness?" The correct term for the hardness or softness of a piece of cellular rubber is compression deflection.

Compression Deflection - Correct Measure of hardness. The weight required to compress a 1 cu. in. cube 25%. ve. Different companies use different kinds of Visco Elastic foam also called memory foam, slow recovery or Swiss Foam. They seem to be based on the foam developed by NASA (see below), but I haven't seen any comparisons. e.g. Isotonic uses something called Conform and ViscoLux. HealthyBack uses a foam from Obus Form

Visco-Elastic Memory Foam (memory foam):
From abed.com

Developed for NASA to relieve extreme G-force pressures. Memory Foam molds to your body contours to help prevent tossing and turning during the night. When you lie down on this amazing material, the heat and pressure sensitive foam reacts to your body's weight and temperature, so that it molds to your exact body shape. This means that whether you sleep on your back, stomach or side, your weight is evenly distributed and your spine remains in a neutral position.

Tests have shown that these mattresses actually improve sleep and increase the level of deep sleep, so you wake up more alert, refreshed and better rested. Recommended by over 25,000 medical professionals worldwide. Naturally treated cover protects you from harmful allergens, resists dust mites, and removes easily for washing.

Problems with memory foam:
There are 3 problems with most memory foam mattresses: no air circulation, Odors and toxic chemicals.
Note: Some memory foam mattresses claim to eliminate these thru various means; latex, different fire retardants, ...

No air circulation:
One problem reported with these mattresses is they do not breath and can be too warm in the summer. I got the following response from abed.com regarding this:

From: "Roseanne McArdle, sleep consultant" <Roseanne@abed.com>
To answer your question regarding humidity, what the article is referring to is the need to sleep on a bed that does not make you sweat. Our foam beds such as the Dormia and the Wellington have Joma wool filling quilted into their covers and this allows for the air circulation your bed needs to have to help regulate your body temperature and keep you from overheating. Latex foam also is well known for helping air to circulate and keeping heat away.
See: Mattresses and Sleep, a pseudo-technical discussion of sleep by a company selling memory foam mattresses

About 15% of people who buy a memory foam mattress report a noticeable odor. For most people, this is a just a minor annoyance that dissipates within a few days to a few weeks and accounts for less than 2% of returns according to Sleep Like The Dead. However, a small percentage of people may report respiratory irritation and other symptoms like nausea and headaches.

Around 2005 there were reports of toxic chemicals in memory foam mattresses and a class action law suit was filed.
Virtually all commercially available mattresses made today are filled with petroleum based foam and then soaked in a pound or more of fire retardant chemicals. These mattresses outgas formaldehyde as they age, which is a known carcinogen. Fire redardants, made of chemicals called Polybrominated diphenyl ethers (PBDEs), build up in our bodies like the banned PCBs and have been associated with neurological damage and cancer."

Comforpedic by Simmons uses a new advanced level of memory foam called, NXG. In its manufacturing process, the foam is created in a VPF (variable pressure chamber) which removes the notorious, yet, unavoidable chemical irritants from the product.

Latex Foam:
From: abed.com Derived from the have brasiliensis, or the rubber tree, latex is the most naturally durable cushioning material available. Latex is harvested in much the same way as maple syrup from the maple tree. The milky white latex is converted into a mattress or pillow in special molds and undergoes four rinsing processes to eliminate odors.

Health Benefits Latex is antimicrobial and dust mite resistant, making it perfect for pulmonary allergy sufferers. It's ecologically-friendly and has no chemical properties or detrimental impacts to the environment.

Additional Benefits Designed for breathability with an open-cell structure and special "pin core" construction, latex allows for ventilation of body heat. It also keeps moisture from building up next to your body. Aluminum core pins transfer curing heat into the foam. As a result, thousands of "pin-core" air-channels enable natural ventilation of the final product. Types of Latex:
Talalay latex - Has less resistance, bouncier, and is more for soreness or those who have or seek relief from pressure point problems.
Dunlop - When all else is equal dunlop is firmer, denser, and may provide extra needed support.

Some companies allow you to select the material for each layer. Some people will combine Talaly and dunlop in different layers.

Blended latex will have a percentage of natural latex mixed with a petroleum based material called SBR that will off gas.

Latex vs Polyurethane Foam:

Latex vs Polyurethane foam:
Latex lasts longer up to 20 years. More exact pinpointed support than memory foam. Does not release the harmful chemicals Made with a much cleaner and less energy intense process Latex is more expensive

Spring vs Foam:
At Spring Mattress vs Memory Foam Mattress -| Essentia they list Natural foam as best in a bunch of categories, but they leave a "?" for spring in categories like durability, low VOC, sleeps cool, because they don't know what kind of topping is on spring mattresses in general.
