King Size Latex Mattress

What is a king size latex mattress made out of?  There is more than one type of latex mattress.  They can be constructed of 100% all natural latex, organic latex, or mixed.  A hybrid type is made of a mixture of latex and memory foam or other materials.  Rest Right Mattress has all three types.  Natural latex is the foundation for all three that we carry.  Natural latex foam is made from tropical trees called Hevea Brasiliensis.  Sap from these trees is harvested and minimally processed to create mattresses that are breathable and lasting.  Not all king size latex mattresses are made the same way.  Differences between each companies growing, harvesting and processing procedures produce differences in the final mattress.  There can even be differences between mattresses by the same brand.  Ultimately these differences are reflected in price.  Additionally, each mattress is built for different individual sleep preferences.  King size latex mattresses can be natural or synthetically produced as well.


What to look for in a king size latex mattress?

There are many characteristics to compare in a King size latex mattress.  Brand, price, material and size are just a few aspects of a latex mattress to consider.  The brand, or manufacturer, is the first impression.  We carry mattress brands that offer latex options.  Which you choose is dependent on whether you want an entirely natural latex mattress or a hybrid model. Our iAdjust mattresses come in three varieties; amenity, all-natural and all-organic.  Our Reverie mattresses are made with a combination of fibers and materials, including latex.  Both brands offer different types of latex mattresses as well as different features.  For example, some of the mattresses are made using the Dunlop method and some using Talalay.  Another thing to look at in a king size latex mattress is the price.  You can be confident when you purchase your king size latex mattress at Rest Right Mattress.  That’s because we have great prices on the great sleep products that you want.  After you know which items you are interested in, give us a call.  In some cases we can offer an even lower price over the phone.

iAdjust Company

For many years there wasn’t a true 100% all-natural or organic king size latex mattress available in the marketplace.  The iAdjust company wanted to change that.  They did so with the production of the iAdjust All-Natural Latex Mattress and the iAdjust Organic Latex Mattress.  Both of these mattresses were designed and constructed using latex throughout the mattress.  The company has been around now for three generations.   They not only develop these mattresses, they also take pride in the finished product.  A hallmark of these mattresses is a three layer comfort system.


iAdjust Customization

Customize your king size latex mattress using the iAdjust three layer comfort system to change the firmness.  By simply assembling the three layers in the desired order, you can change the mattress to be anywhere from soft to firm.  If you want a firm mattress, stack the layers with the firm layer on top followed by the medium and soft ones.  For a side sleeper, use the firmest layer as a base layer and top the stack with the softest layer.  A medium firm layer on top can be ideal for someone who moves around a lot as they sleep.  Those with inconsistent sleeping positions might prefer this setup as well.  Couples, who need a compromise due to different sleep preferences, might also try this arrangement.  However, the point of the three layers is that you can adjust them until you find the perfect mattress firmness.  This way you can address pressure points by changing the firmness.  The sections all come with a separate cover around them to protect them from any damage.  Then the mattress cover goes around them holding them in place and further protecting your investment.



Latex Process

A couple processes can create a King size latex mattress.  Which process is used depends on if the latex is natural, organic or synthetic.  iAdjust models use the Dunlop process which has been around for many, many years.  It involves extraction of the tree sap and the mechanical separation of the sediments within the sap.  To achieve this, a centrifuge container rapidly spins the sap with centrifugal force prior to molding and baking, removing impurities.  The end product is a durable Dunlop latex foam mattress that is made without added harmful chemicals.  Another process for manufacturing latex is the Talalay process.  It has been used almost as long as the Dunlop process.  However, the Talalay process includes the use of chemicals to vulcanize it after molding and freezing.  This way of processing leads to more consistent texture.  Talalay latex can be Oeko-Tex Certified.  That means it is tested to be sure any chemicals used in production meet emissions regulations that are in place to protect consumers.  Synthetic latex is foam made from petrochemicals.  As such, it can have an unpleasant scent and different feel when compared to natural latex.  Another drawback to synthetic latex is it tends to be insufficient when it comes to durability.



Prices on king size latex mattressking size latex mattress

For obvious reasons one type of King size latex mattress will cost more than others, the organic.  There are so many organizations involved in ensuring an organic mattress is truly organic.  Therefore there is more time and effort put into development of these mattresses leading to a higher production cost.  This mattress is a valid choice even with the slightly higher price tag.  That’s because the price comes with certainty that the mattress well exceeds the governmental regulations.  In terms of chemical usage, the organic model removes any concern from the equation.  A natural king size latex mattress costs less than the organic but more than synthetic latex beds.  Natural latex undergoes a harvesting process and development very similar to the organic.  It only lacks the more stringent standards and requirements of a certified organic mattress.




How soft or firm a King size latex mattress feels is measured by the ILD number.  ILD numbers, otherwise known as the Indentation Load Deflection rating, typically are listed as a range.  For the iAdjust adjustable three layer system, there are three separate ILD numbers, one for each layer.  The medium layer on this King size latex mattress has an ILD range of 30-32.  That’s really the number of pounds of pressure it would take to generate a 25% indentation in four inches.  The range for the softer layer is 19-22 and the range for the firm layer is 37-40.  Each of the layers in the iAdjust mattresses has a different density and therefore a different ILD.   The three layer system is integrated into all of the iAdjust models we carry, but it is not the same in all three.  The iAdjust Natural Latex Amenity has the system but not all the layers are natural latex.  Both of the all-natural and organic iAdjust series contain three layers of latex.


What Comfort Level is Best for a King Size Latex Mattress?

Soft Comfort Level:

All the comfort levels of king size latex mattresses are not alike.  Some come in a soft comfort which is ideal for a person who sleeps on their side.  The general idea is that with a softer firmness, a side sleeper can sink into the bed.  A person’s hips dig into the upper layer and ultimately the spine is kept at a more aligned position.  While this is more comfortable for your back, it can also benefit you in the long run.  So much time is spent in bed.  If your back is twisted or curved for long periods of time, pain may develop.  A softer mattress can alleviate some of this concern for a side sleeper.

Medium Comfort Level:

The most commonly selected mattress firmness for a king size latex mattress is a medium firmness. The reason being, medium firmness most often satisfies both side sleepers and those who sleep on their back.  People who sleep in these positions tend to prefer it.  Softer mattresses can have too much give while firmer ones not enough.  When sleeping on your back, you want to have a little flex in the midsection.  This allows the muscles to relax without sacrificing spinal support.

Firm Comfort Level:

Interestingly, stomach sleepers only account for about five percent of sleepers.  It is important for those who choose this position to choose a firm king size latex mattress.  To avoid putting pressure on your spine as you sleep on the stomach, a flat supportive surface is required.  Otherwise, the belly will sink into the bed and pull the back into an uncomfortable position.  That’s why most stomach sleeper’s like to sleep on a firm mattress.  This firmness level provides support to help keep the back aligned properly in this particular sleep position.


What To Look Out For When Buying a King Size Latex Mattress?

When making the purchase of a king size latex mattress, there are several things to be cautious of.

  • sometimes packaging and marketing can be deceiving, whether it is meant to be or not.  If choosing organic is a priority for you, be careful to note whether a mattress is truly organic.  Some companies will label a product organic when it in fact is only partially so.  For example, maybe the cover is made with organic materials and the rest is inorganic.  Look for certifications that indicate a latex mattress is made from natural or organic latex.  If there are no certification labels, then it could be made from synthetic materials.
  • When there are organic certification labels, read them.  Certification programs have different levels of certification.  One label might indicate a mattress is mostly organic, while another will indicate it is 100% organic.
  • Outside of the labeling, a king size latex mattress can be made from either Talalay latex or Dunlop latex.  Personal preference will determine which of these latex processes yields the latex that will best fit your needs.  Dunlop is durable, and  Talalay is more processed and does not last as long.

Do Not Stress About the Firmness

Most are adjustable bed firmness

One piece of advice for those considering a kings size latex mattress; don’t stress over the firmness too much. There are options that provide multiple firmness capabilities in a single mattress.  By selecting one of these mattresses with three comfort levels, one of each firmness level, you can have it all.
