GENERAL FEATURES

  • Natural latex (isoprene foam) mattress is made of pure natural latex in sponge, mousse form, without mixing with Latex Synthétique (synthetic latex).
  • A light, pleasant fragrance.

  • Sponge, mousse enables the mattress to be soft, strong, unmeltable, unflattenable (deflection) or degraded by time.

  • The optimal elasticity of KYMDAN natural latex (isoprene foam) mattresses helps support a user’s spine in all sleeping positions. To meet varying customer demand for products, that have appropriate features, KYMDAN mattresses are produced in three different levels of firmness:

Firmness Level 1: Standard Hard (SDH) mattresses are suitable for regular use by the average customers who range in age from newborns to adults and weigh less than 80kg (176 pounds).

Standard Hard mattresses have the lowest level of firmness of all KYMDAN mattresses. Research shows this firmness level to be suitable for consumers of average weight. KYMDAN does not produce mattresses at softer levels because of risks related to sagging of the spine. This can negatively affect a user’s health and KYMDAN's prestige. 

Mattresses do not compress or develop hollow areas for users weighing less than 80kg

Firmness Level 2: Special Hard (SH) mattresses are suitable for customers unaccustomed to mattresses because they use floor mats or plank beds, for customers with minor spinal complications or for customers weighing 80kg - 100kg (176 pounds - 220 pounds).

Mattresses do not sink or develop hollow areas for users who weigh 80kg - 100kg

Firmness Level 3: Super Hard (SSH) mattresses are suitable for customers with serious spinal conditions, customers weighing over 100kg who stay in bed for extended periods. Mattresses of this type are also suitable for use in massage facilities.

Mattresses do not compress or develop hollow areas when users weigh over 100kg

This is one of the 15 Outstanding Features of KYMDAN mattresses (see details)

 

Note: Spine-related medical conditions:

  • Spinal degeneration.
  • Spinal disc herniation.
  • Damaged muscles and spinal ligaments.
  • Soft tissue injuries.
  • Pain in lumbar spine with unknown cause.

 

Physicians who specialize in bone and spine disorders recommend KYMDAN natural latex (isoprene foam) mattresses (see details)

Thickness specifications of KYMDAN mattresses:

Guided by the principle “Perfectly Satisfying Customer Demands,” KYMDAN produces assorted mattress types having various functions and thicknesses in order to meet the various demands of a diversified clientele.

Measurement Uncertainties

The Measurement Uncertainties related to length and width of mattress products is ± 3cm according to the Statement of Quality Standards for Products and Goods (with additional statement on September 09th, 2014)

 

  • Open sponge structure allows air circulation and gives aeration and cooling sensations to user’s back, regardless of climate conditions. KYMDAN mattresses have a structure of interconnected air bubbles that creates aeration via natural air circulation. Large square holes on the mattress base surface and round holes on the mattress top surface help improve aeration by adding surface contact area. (KYMDAN mattresses were called KYMDAN Odorless, Ventilated Latex mattresses before 1975). Such structure creates a suitable distance between the load bearing axes at the mattress base to help evenly distribute the support force applied to user's body. 

This is one of the 15 Outstanding Features of KYMDAN mattresses (see details)

Correct way of mattress test:

KYMDAN mattress - high Tensile force, high elongation at break

 

 

Counterfeit mattresses: torn – bad quality, damaged

Differentiation of KYMDAN mattresses and counterfeited mattresses
after one year of use

QUALITY STANDARD CHART OF KYMDAN MATTRESSES AND PILLOWS

KYMDAN is the only company in the latex mousse industry in Vietnam that publishes detailed technical parameters of product quality on our website. There are many latex mattress sellers in the market claiming that their mattresses have similar product quality with KYMDAN mattresses. If that is true, why don't they publish their technical parameters of quality for the consumers to see?

(*) : The small amount of Cu and Mn is an insignificant amount to be sufficient enough to cause aging of the natural latex. A Cu and Mn content that IS NOT LESS than the quantity listed about or 10mg/kg, will cause severe and rapid aging of the natural latex.

 (**)  : “Many people often misunderstand ISO as simply being a quality management system for products, but in fact ISO is also a test method used for testing certain characteristics of the particular product” (reply from Quality Assurance and Testing Centre3).

 KYMDAN does not use TiO2 to bleach the latex. Therefore, KYMDAN latex products are not white, but rather the natural color of natural latex.

TiO2 is a toxic occupational hazard, its particulate matter can be found suspended in the air and cause cancer when inhaled (TiO2 is listed as one of the approximately 900 banned chemicals, that cannot be present in products when imported into the USA).

Notes:

  • Specifications of KYMDAN Company exceed all other latex mousse brands in Vietnam and in the world. In fact, the mattresses themself are mousse blocks (not just thin mousse cover layers as in other mattress types), which help users feel more comfortable. In addition, KYMDAN mattresses are safe because they are made from natural latex. Thanks to above features, KYMDAN is a luxurious product for the Japanese market and is popular with wealthy, high-class clients.

  • Based on the quality levels indicated in the technical sheets (available as of 9 February 2009), the quality of KYMDAN mattresses have, literally, increased up to 30%, yet official publication on quality enhancement is humbly kept at 20%.

 

Elastic mattress:

  

KYMDAN Mattresses - do not flatten (indented, hollow), high compressive strength,

high elasticity, instantly return to their original shape and size

 

Flat and not resilient (sunk, sunken):

The mattress was flat and not resilient (sunk, sunken)
Even when not being subjected to load, the mattress still sunk,
sunken – not able to return to its original shape and size

 

Packaging and delivery:

Upon product counseling, our sales staff always presents bare KYMDAN mattresses to customers so that they could visually check and feel the products directly. Upon delivery, if the mattress cover is ordered, the covered mattress in a PE bag with KYMDAN logo will be delivered.

 

Delivery staffs are responsible for transporting and placing the mattress on your bed and reclaiming the PE bag to avoid the fraudulent cases carried out by illegal competitors, in which the bags with KYMDAN logo are re-used for other mattresses of lower quality, hence cheat customers with counterfeit products. In case the purchased mattresses is yet to be used, KYMDAN’s packages will be left with the customers to assure cleanliness and avoid contamination for the products.

Recommendations: Customers should buy KYMDAN products at our official outlets or agents. In addition, clients should form the habit of checking the mattresses directly from the packaging; this is specially required when KYMDAN products are bought at any mattress shops not included in KYMDAN’s distribution system.
