1.Natural Latex was discovered 500 yrs ago in Brazil(Heavea Brasiliensis).It is now grown in india & South East Asia.India produces one of best natural rubber in the world.

1.SBR Latex was discovered after the second world war,in the 1950's.

1.Polyurethane Foam was invented after the second world war in the 1960's.

2.100% NR Latex Foam was invented in 1929 by Dunlop and is now produced commercially and india have lot of small scale industries.

2.SBR Latex was used to produce foam with the blend of natural latex in the early 1960's.

2.Polyurethane Foam was produced on a commercial basis in the early 1960's.

3.NR is derived from rubber trees as a milky juice which is naturally found to be durable,non toxic & bio friendly.

3.SBR Latex is produced from petrochemical product and doesn't have the inherent everlasting resilience like Natural Latex Foam.

3.Polyurethane Foam is produced from polyol & TDI(isocyanide)discharges toxic fumes.

4.NR Foam recovers in a very lively and quick manner and dampens the movements without disturbing the sleeping partner because of its inherent resilience.

4.SBR Latex doesn't recover as efficiently as Natural Latex Foam because it doesn't posses the inherent properties of resilience.

4.Recovers very slowly and doesn't dampen the vibrations quickly because of its poor porosity and plastic cell structure.

5.The excellent rate of recovery from deformation has always been a feature of great value in the properties latex foam.

5.The recovery of SBR foam is not as good as "Latex" foam and loses its hardness and shape while in use after a period of time.

5.Polyurethane foam gets deformed,breaks downs and loses its hardness while in use.

6.The NR foam mattresses give perfect support without pressure to the body in which ever position a person lies.It is self ventilating as it has millions of tiny interconnected cells.

6.Doesn't give perfect support and ventilation efficiently as good as natural latex foam.It doesn't let out hot air and perspiration transmitted from the body as quickly as in the case of "Latex" foam.

6.Polyurethane foam has a very poor porosity and it doesn't dissipate body heat and sweet effectively.

7.NR foam has the highest natural bacteriostatic & bactericidal properties which is unmatched by any other foam.

7.SBR latex foam doesn't have bacteriostatic & bactericidal properties.

7.Polyurethane foam doesn't have natural bacteriostatic and bactericidal properties.

8.NR foam can be used again & again for its lasting durability and resilience which has its lasting durability and resilience which has the capacity to withstand hard wear without collapsing & loosening shape.

8.SBR foam can't boast of lasting durability and resilience and the capacity to withstand hard wear and tear without collapsing and losing its shape as good as Natural Latex Foam.

8.Polyurethane foam can't be used again and again because of its poor durability and poor resilience.It doesn't have the capacity to withstand hardwear and tear without collapsing and losing its shape like latex foam.

9.NR foam has a unique pattern of small pencil hole caitations and the hardness characterstics are isotropic and all surfaces present an uniform smoothness giving maximum comfort.

9.SBR foam has a unique pattern of small pin hole cavitations on both sides and the hardness characterstics are isotropic and all surfaces present an uniform smoothness giving sufficient comfort.

9.Generally polyurethane foam doesn't have the unique pattern and cavitation of latex foam and doesn't give maximum comfort.

10.SBR foam never goes lumpy,never creates dust of fluff but doesn't have the inherent natural bacteriostatic and bactericidal properties.

10.Polyurethane foam can go lumpy,create dust or fluff and is no good for sufferers from asthma and other allergic complaints.

11.NR foam is only slightly affected by wide changes in humidity and temperature and the mattresses do not become damp and will remain well ventlated even when not in use.In addition,perspiration is quickly dissipated and passed out of the mattress.

11.SBR doesn't dissipate heat,moisture and perspiration as quickly as Natural Latex Foam.

11.Polyurethane foam is widely affected by humidity and temperature and the mattress dose become damp and will not self ventilate when not in use because of its poor porosity.Perspiration is not quickly dissipated and passed out from the mattress like Latex Foam.

12.On ignition,NR foam produces black smoke mostly containing unburnt carbon.

12.On ignition,SBR foam produces black smoke containing phenolic substances which are toxic.

12.On ignition,Polyurethane foam produces toxic fumes which can suffocate and cause physical injury to the respiratory system and cause serious damage.
