Types of mattresses

Should your mattress contain Open Coil Springs, Pocket Springs, Visco Elastic Memory Foam, Latex, or have predominant Orthopedic properties?

Open Coil Springs - Modern day open coil mattresses are greatly improved on those of yester year. Manufacturers incorporate a variety of spring systems to suit the individuals' need for comfort and support. For instance, “with twice the number of springs as a standard mattress, the dual spring provides double the comfort and support of an ordinary bed.

  • Bonnell coils are the oldest and most common. First adapted from buggy seat springs of the 19th century, they are still prevalent in less expensive mattresses. Bonnell coils are hourglass-shaped, and the ends of the wire are knotted or wrapped around the top and bottom circular portion of the coil and self-tied. Normally these mattress have 450  3"springs in a double mattress.
  • Offset coils are designed to hinge, thus conforming to body shape. They are very sturdy, stable inner springs that provide great support. An example of this type of coil design is usually mentioned on the mattress label as being "Posturepedic, Postureline or Posture something" coil system and often features large amounts of springs usually over 1000 of them in a double mattress.
  • Continuous coils  Work by a hinging effect, similar to that of offset coils. In a basic sense a continuous coil is simply that, one continuous coil in an up and down fashion forming one row (usually from head to toe) of what appear to be individual coils. The Spring System gives progressive support, meaning the more weight applied, the more the springs respond. The advantages are that they provide a greater but gentler support in creating a firm mattress, the continuous coil design is usually mention on the mattress label as being " Mira coil or Flexform" to name two, usually containing around 651 springs in a double mattress.



Pocket Springs - Housed in individual pockets of fabric, which are tied together, each spring is allowed to move independently and therefore mold to the shape of the body and adjust to differing weights.  These spring units vary vastly from the number  and the firmness of the springs that they contain, they also generally do not have any rod ends ( the wire that goes completely around the mattress) which makes them unsuitable for slatted bed bases.

Visco Elastic Memory Foam - NASA technology brought into your bedroom giving pure science to help you sleep better as advertised. This high density foam has magnificent capabilities of absorbing energy and is extremely temperature sensitive. The material forms itself to the shape of your body contours giving maximum support and allows the spine and joints to rest in their natural position.

Memory foam was never used in the space program but was subsequently used medically, for example by patients who used to lie in bed on hard or very firm mattresses for long periods of time without regularly moving such as being bed-bound after a paralyzing stroke.The pressure over some of their bony regions decreased or stopped the blood flow to the region causing bed or pressure sores which leads to gangreen, Memory foam mattresses helped remarkably to decrease this. Memory foam was initially too expensive for general use, but in recent years it has become cheaper to produce and is now widely available. Its heat-retaining properties may help some pain sufferers who find the added warmth helps to ease the pain of painfull joints.

Latex - A latex mattress changes its shape to the precise contours of your body giving pressure free support to your spine, shoulders, hips and limbs. A good choice for sufferers of allergies and related respiratory diseases.
Latex is a relatively new product to the market to be used for mattresses. Made from either Natural or Synthetic latex, a latex core can virtually last forever and won’t lose it’s bounce. Natural latex is made from natural rubber, taken from the rubber tree and synthetic latex is made from a mix of different chemical compounds. Although synthetic latex is a man made product, it feels virtually identical to a natural latex product and the only difference between them is the form of latex in the manufacturing process.

 Orthopedic - An active support system enables the mattress to be used edge to edge and is specifically designed for that firmer feel for those who require extra support. This is achieved by using a 12.5  gage spring which of a thicker construction than the standard bed spring.  In the 1950s, many manufacturers of mattresses made an effort to improve their products and give them a product edge over competitors. It was in the midst this culture that the concept of a mattress that was medically superior was born. The Orthopedic Mattress was the final product of many years of research and development from many different companies.There is no government standard or official designation that will qualify one mattress orthopedic and the other not. This reality has created much confusion in the bedding industry, to the point that the typical consumer is not able to determine if a mattress is orthopedic or not.
Which does not help you the customer very much, but if its got orthopedic on the label it means its going to be a firm spring unit with strong rod ends.

So which mattress should you choose ?
