Innerspring Mattresses

Innerspring mattresses are the most common and popular type of mattresses. The support structure of these mattresses are made up of coils. The shape of the mattress is retained with the help of this border wire. The perimeter of each coils is connected to a wire that borders the mattress. Special springs are used at the edges to give a firm support to the edge. The upper layer of the mattress is separated by a tough padding or insulator, or a layer of wire netted together that prevents it from settling into the springs. The number of coils that may be present in the innerspring mattresses varies from 300-800 and largely depends on the size of mattress. The relation between the thickness of the coil wire and the number of coils used is inversely proportional. However, more the number of coils, more comfortable will the mattress be. There are different types of coils that can be used in innerspring mattresses. The technique used to connect the coils greatly affects the shape, comfort and durability of the mattress. The list below gives a brief idea about these coils.

  • Pocket Coil: These are cylindrical in shape and each spring is independently wrapped in a fabric. Each spring supports only the weight on it. Thus, every coil works independently and the weight is not distributed. This type of coil used in innerspring mattress, is the best choice for people who turn too much while sleeping, as this will not disturb their partners.
  • Open Coil/ Bonell Coil: These coils have a shape of hourglass and each coil is joined to the adjacent coil by a wire that is helical. Initially these coils provide good support, but they gradually fatigue with time.
  • Offset Coil: These are similar to open coil, but they are square shaped at the top and are more expensive.
  • Continuous Coil: A row of coils is made up of a single wire and this row is connected to adjacent row using a helical wire. The innerspring mattresses made up of such coils can maintain their shape for a longer period.

Foam Mattresses

These were initially manufactured for astronauts of NASA, in 1970, to help them get relief from the gravitational force they experienced during the takeoff of a spaceship. The typical characteristics of these mattresses is that they take a shape in the way the pressure is applied and come back to their original form after removal of the pressure. In 1980, these mattresses were introduced in the market for consumers. The foam mattresses are made from either of the three types of materials: viz. viscoelastic material, latex or polyurethane.

The viscoelastic foam mattresses are expensive, but durable and are more popularly known as memory foam mattresses. Latex mattresses are comparatively popular as they make the sleeper feel warm in winters and cool in the summers. The viscoelastic mattresses are sensitive to changes in the temperature. Latex mattresses are recommended for asthma and allergic people as they resist dust and are hypoallergenic. Foam mattresses are difficult to adjust with, in the initial period of use and are not a good choice for heavy people. Consumers always get confused while opting for latex or memory foam mattress.

Air Mattresses

These mattresses provide the facility to adjust the comfort level. The air in the mattresses can be adjusted to change the firmness. Air mattresses with dividers are available and air in both the sides of these mattresses can be adjusted to different levels. Air mattresses are portable and are chiefly used for camping or outdoor trips. They look similar to innerspring mattresses, but in these mattresses, the coil is replaced by air. Air mattresses are also used to a great extent in hospitals as they can be used for pain relief. Initially, these mattresses were very costly, but have gradually become economical.

Water Beds

Water beds are not very popular as compared to other types of mattresses. A unique feature of water beds is that their temperature can be controlled. People living in cold regions would always prefer water beds. Soft-sided and hard-sided are two types of water beds. The hard-sided water beds have a wooden frame that provides rigidity to the bed. Soft-sided water beds have recently been invented and so are hybrid beds that use other conventional techniques and water bed. Water beds are recommended for allergic people as the bed can be cleaned very easily with just a wipe. However, there is always a fear of leakage with water beds.

Horsehair Mattresses

The relatively good moisture regulation, warmth retention, and air permeable padding is made by gathering the hair into a spiral formation. Like sheep wool, horse hair can also take in up to 20% its own weight in moisture, without feeling wet. A portion of mane or cow hair makes the mattress more adjustable, whereas hair from a horse’s tail results in a harder mattress. Since horsehair mattresses are very heavy, they will still today often of offered in 2 sections. In the price catergory, horse tail hair is today the leader.

Kapok Mattresses

Kapok are the silky fibers around the seeds of any of several tropical trees of the bombax family. This "plant down» is very light, fine, and warmth insolating. Besides being anti-bacterial, germ free, and resulting in a firm but elsastic mattress, it is of value because it can take in much moisture and hold warmth. Although the manufacturing of horsehair mattresses is similar, a kapok mattress is much lighter than other fully stuffed mattresses, but in opposition to this, cannot be worked up.

Coconut Fiber Mattresses

This firm, form maintaining natural mattress utilizes the hard fibers of coconut palms. They are insensible to moisture. These mattresses are especially recommended for people with allergies to animal hair. The coconut fibers are not suitable for thick filling, but for flat mats wrapt up and quilted in jute. A mattress of the customary height consists of about 5 such padding mats. Together with a layer of wool, they reach a height of approx. 6 cm and will of offered as flat mattresses. The sleep support will be somewhat elastic in combination with sisal fibers.

Rye Straw Mattresses

This pure straw spring mattress is suitable for proclaimed «hard sleepers». The pure rye straw is quiltedwith a jute fabric. Because the straw is about a quarter of its original volume when pressed together, the mattress is very firm. Although in the formation of this design, it is no longer cooled as quickly as before, one should turn it regularly. If it is in the over 20 kilograms weight class, this could be difficult. All natural mattresses emit a distinct animal or plant smell. In the long run, alternative mattresses - even with good care - do not keep their form. The filling must, with every material and all workmanship, after a time be worked up. The guarantee’s promises are realistically good for up to 5 years with treatment.

Why Spring Mattresses?

Advantages of spring mattresses over other types of bedding:

  • Spring Mattresses out performs all other types of bedding from stand points of Support Comfort and Durability
  • The gentle up thrust of Spring mattresses lets body relax completely.
  • No bottoming out (center sinking as regularly seen in coir, foam or cotton Mattresses), hence good spinal support for better ergonomics.
  • Readily adjusts to any body contours and movement.
  • 70% of developed world sleeps on spring mattresses. Indian Population is fastly adopting this transition to Spring Mattresses.
  • Spring mattresses provide free air circulation throughout. Hence no heat builds up and the air passing continuously refreshes the mattress.
  • The core of the mattress is formed by a high coil count innerspring unit to provide ideal support.

Spring mattresses are the most preferred sleeping surface in the world and this makes it an evolving product for India.
