Why We Don't Use Memory Foam In Our Mattresses

We are sometimes asked why we don't use memory foam in our mattresses; or why we don't sell memory foam mattresses and pillows. We believe that it is important for the sleeper to be able to move easily and being immediately supported in the new sleeping position which can only be achieved by a very resilient latex foam or springs – not memory foam.

Additionally, memory foam, aka visco elastic or "visco" foam, is a type of polyurethane foam made from petroleum and can harbor potentially toxic chemicals (which are often undisclosed) and flame retardants. So naturally (or un-naturally) this does not pass the smell test - or our "no plastic foams or fillers in the mattress" test.

Which is why we only use natural latex foam as a cushioning material in our mattresses.

Comparing latex and memory foam


LATEX

VISCO (memory foam)

Materials

Natural rubber* (+ synthetic latex SBR in blended latex)

Polyurethane

Body conformity, support & body surface pressure

Optimal body conformity through natural elasticity and homogeneous cell structure.

Follows the body’s natural contours. Removes areas of high pressure.

Provides individual support and comfort in any sleeping position.

Distributes body pressure evenly – avoids bed sores BUT for healthy people pressure distribution is generally not a problem and through the large contact area there is greater resistance to turning and impaired freedom of movement resulting in the sleeper waking up trying to turn.

Resilience

High resilience provides quick recovery of the shape and support characteristics of the mattress core when the sleeper turns or moves during the sleep process allowing easy movement.

Very low resilience results in rigid body weight impressions  which impair the sleeper from moving adequately.

 

Ventilation / Sleeping climate

Open, interconnected cell structure and pin core design provide excellent ventilation resulting in a dry and healthy sleeping climate.

Closed cell structure results in very limited airflow through highly compacted cells.

Large contact area generates  greater heat build up and reduced air flow.

Health

Öko-Tex 100 Standard certified (free of harmful substances).

No certification – (undisclosed chemical composition)

Beneficial to Allergy sufferers

Inherently hypoallergenic, bactericidal and anti-fungal, does not harbor dust mites.

-

Durability

Minimal height and hardness loss due to natural resilience of raw material and cell structure

Long lasting and exceptionally durable.

80 years proven track record.

*At European Sleep Design we use only all-natural latex, not blended or synthetic latex.
