Specifications
GENERAL FEATURES
- Kymdan foam mattresses are pale cream or pale pink, contain all Natural Latex in a foam form, and do not contain any synthetic latex. In particular, Kymdan mattresses are a single block of natural latex foam (not just a thin layer of latex foam on the surface like other mattresses); hence, they can provide better comfort.
-
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 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 density:
|
Foam Density Level 1 (SDH): With a foam density 175-200 kg/m3, these 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). Mattresses of foam density Level 1 have the lowest level of foam density of all Kymdan mattresses. Research shows this foam density 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 |
|
Foam Density Level 2 (SH): Foam Density 180 - 210 kg/m3 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 |
|
Foam Density Level 3 (SSH): Foam Density 190 - 220 kg/m3 mattresses are suitable for customers with serious spinal injuries or illnesses, especially those who are bedridden for long-periods during treatment. This mattress density is also suitable for user weighing over 100kg. |
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 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)

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 OR EQUAL to the 10mg/kg listed above 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 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:
| DOMESTIC MATTRESSES | EXPORT MATTRESSES |
| PACKAGING | |
|
Mattress is packaged in a lightproof Polyethlene (PE) plastic packaging that is a solid color grey. The opening of the packaging is double folded and closed securely with tape.
|
Mattress is packaged in a 5-layered carton box, with the Kymdan name printed on the box and secured with straps. The carton box will have information on the mattress product inside, a warning sticker and safe transportation guide.
|
| PRODUCT DELIVERY | |
|
When delivering, the delivery staff will place the mattress directly on your bed at your request. The PE packaging will be collected by Kymdan to return to the company for proper disposal, to help with environmental sustainability. In case you have purchased a mattress but do not wish to use the mattress immediately, our staff will deliver the mattress with all the proper packaging to ensure the cleanliness of the mattress and avoid dust contamination of the product. Please note: the mattress should be stored laying flat, do not fold or roll the mattress. When you receive your mattress product, please directly check the mattress within the packaging, especially when purchasing a Kymdan mattress that is not one of Kymdan’s official distribution channels. |
For international markets, Kymdan Company uses a courier service to deliver products. For the safety of our customers, we do not deliver Kymdan products to your room, but only deliver to your door. You should not package a Kymdan mattress by yourself and hire a separate courier service to ship the mattress from Vietnam to the USA. Many shipping companies wanting to cut down on expenses will intentionally (whether with or without your knowledge and agreement) remove Kymdan's packaging and repackage the mattress/es by rolling, folding, compressing, and squeezing to reduce storage volume during shipping. Such conditions will cause damage to the mattress after extended periods and can cause odor contamination from other products stored together during shipping. |
