1. The optimal firmness of KYMDAN mattresses (see details) supports and helps straighten the spine, preventing it from sagging due to sunken or hollow areas in the mattress. This extremely important feature helps avoid back pain and is especially beneficial for the spinal degeneration of elderly people, as well as the spinal development of children.

2. The mattress structure provides suitable distance between load bearing axes and optimises load bearing ability; the force acting on the body of a person lying on is distributed evenly. By eliminating pressure points, this feature assists users to feel more comfortable, optimally supports their body and spine in any sleeping position, and aids in proper sleep posture.

Note: the force distribution density is according to the color chart
 Higher pressure distribution
 Lower pressure distribution


Benefits of this feature are evident when a user kneels or lies propped up on elbows on the mattress (e.g. for reading). In such cases, this feature has helped result in the dramatic reduction of joint pain normally associated with pressure-points.


3.Mattress elasticity is obvious only on surfaces that are in direct contact with force. Expansion or contraction produces no sound or vibration that can spread. As a result, when a user changes sleep position, nearby sleeper is not negatively affected.

For families with young children, the effects of such feature are particularly obvious. Children's sleep would not be disturbed even if the mother frequently moves or changes sleep position.

4. An open foam mattress structure allows air circulation and increases contact surface. The mattress base has large square holes and the mattress top surface has small round holes, resulting in extremely high aeration that eliminating moisture build up due to heat while laying down (Before 1975, KYMDAN mattresses were called KYMDAN Ventilated Latex mattresses).
This special feature is great for parents with babies that occasionally wet the bed. Due to the structure of the foam openings, which allows liquid to flow through the permeable mattress.
5. Thanks to our purification techonology, we are able to eliminate all toxic constituents such as heavy metals (mercury, arsenic and cadmium) to produce a mattress that is safe for direct contact with the consumer (see test results).
6. KYMDAN products have no nitrosamine, ensuring user safety. This substance is common in the rubber processing industry and can cause cancer via contact (absorbance into the body through skin and sweat glands).
7. KYMDAN mattresses are insect resistant. The mattress is not suitable habitat for insects, so there are no insects inside. Without insects crawling, biting or stinging, users can have a worry free sleep. KYMDAN mattresses also protect a user from any germs spread by insects.

Children may cry in the middle of the night and parents are unsure as to why. This could possibly be due to bed bugs biting, causing a burning sensation. The KYMDAN Natural Latex mattresses are anti-dust mite and anti-insect. In simply terms, bed bugs does not like to live in the KYMDAN mattresses. This will no doubt give parents peace knowing that their children are have a safe and healthy night's sleep.
8. Made of natural rubber, the product degrades naturally at the end of its service life. This eminent factor meets ecological standards for protecting the environment in relation to solid wastes that cannot degrade. Products of other manufacturers do not meet environmental standards so well.
9. Are fire retardant, as shown in their non-flammable ability to; not ignite when a burning cigarette comes in contact; not ignite when a forgotten iron has been left on; not ignite with a red hot charcoal (no flame); not ignite due to high temperature metal particles from welding sparks; not cause fire outbreaks the flames to quickly spread; absorb water quickly thanks to their open foam structure which allows for easy fire extinguishing with water.
10. High elasticity is normal in natural rubber. However, KYMDAN's products have perfect elasticity so that they return to their original shape and size even after bearing intense and continuous force. This feature keeps KYMDAN mattresses from compressing and developing hollow areas during long use and prolongs service life.
11. With unique technology, KYMDAN products have great mechanical strength and could easily bear high and continuous pressure loads without being damage. Such bearing capacity is proven in tests done by KYMDAN Company. After being subjected to a 10-ton roller moving back and forth 200 times, KYMDAN mattress products remain intact and undamaged, thus, demonstrate the amazing sustainability of KYMDAN mattresses.

With this outstanding characteristic, KYMDAN mattresses have won the hearts of families with young children due to its excellent ability to endure extreme compressions from children running, bouncing and jumping on them. Moreover, a child will not be hurt when falling on the mattress.

12. Naturally, natural rubber latex does not have high aging ability. However, due to unique know how, KYMDAN mattresses have high aging ability and quality does not change over time, prolonging service life to an average of twenty-five years. Service life can even be up to thirty years if the mattress is used and maintained in compliance with instructions in the warranty, (See User’s Guide and Mattress Warranty sections).

Many private businesses in Vietnam that produce products such as motorbike saddles or lounge suites buy used KYMDAN mattress material to use in their products. Such businesses claim that their products are made from KYMDAN products and the reason for such advertising is that KYMDAN mattresses have long service life and quality indicators such as elasticity and high tensile strength change little over time.

KYMDAN hereby states categorically that there is no policy of providing KYMDAN mousse as raw materials for other businesses. All advertisements or claims from other companies suggesting that products made from KYMDAN mousse are false or such products are made from previously owned KYMDAN latex mattresses.

13. Thanks to their elasticity, KYMDAN mattresses are easy to roll up and easy to transport; also, beds equipped with KYMDAN mattresses are easy to make a bed.

Please note that:

  • Some other mattresses made of natural rubber are substantially heavier than KYMDAN products (e.g. 6-12kg heavier for mattresses having specifications of 1.6m x 2m x 0.15m and 1.6m x 2m x 0.20m). In addition, the quality of other mattresses cannot rival the quality of KYMDAN products...
  • Especially in the case of large mattresses, some mattress products made of other materials are as heavy as KYMDAN mattresses. However, because they cannot be easily rolled, transporting such products is difficult and requires at least two persons. On the contrary, KYMDAN mattress products can be rolled and transported easily by a single strong person (see the video).
14. Bad odor of rubber latex is absolutely eliminated from KYMDAN products. Our mattresses have a light, pleasant fragrance.

Any mattress product that has unpleasant rubber odor is definitely not a KYMDAN product.  Genuine KYMDAN mattresses have a light, pleasant fragrance. 

Thanks to the preeminent features of the products as mentioned above as well as the secrets of absolute deodorization of the rubber smell, KYMDAN has become the only Vietnamese company with stable export of latex mattresses to the developed countries in the past 20 successive years because these markets demand mattresses to be strictly odorless.

15. The natural latex foam (open cell) of KYMDAN mattress and pillow products has received validation from UL - Underwriters Laboratories, USA for being Bacteria Resistant per UL ECVP 2282 (tested using SIAA Direct Contact Shaking Method) and Mold Resistant per UL ECVP 2283 (tested using Japan's JIS Z 2911:2010 test method).

By purchasing a KYMDAN mattress you are not carrying germs into your home and after a long period, if your living environment is not properly cleaned then the KYMDAN mattress will not be a place for diseases to develop.

Those listed features have made KYMDAN products astonishingly unique and have been the main factor to maintain KYMDAN's good reputation.
