Basic Performance

Compression Characteristics

BREATHAIR® has low hysteresis loss and high rebound properties for a cushion material. When used in mattresses or in cushions, these properties make it easy to turn over with comfort.

Compression Characteristics

Durability

The durability of BREATHAIR® was tested using two different methods.

Measurement at 70   and 50% compression rate

sample subjected to compression rate of 50% and then released 80,000 times

Air permeability

BREATHAIR® displays air permeability on a remarkably higher level than that shown by polyurethane foam and polyester fiber cushion.

Mattress Bedding: Internal Temperature and Humidity

Toyobo uses its skin model method to measure the temperature and humidity between the sleeping body and the mattress.

Mattress Bedding: Internal Temperature and Humidity

These mattresses are cool in summer, and when wrapped in a mattress cover they can also retain heat and remain comfortable in winter.

Water Draining Characteristics

BREATHAIR® is quick to dry and is also washable.
Polyurethane is still not dry 24 hours after washing.

Body pressure dispersal

BREATHAIR® does not concentrate stress; it has outstanding load dispersal characteristics.

Anti-bacterial properties

The structure of BREATHAIR® is made up of a series of continuous fiber loops and as such there is no fiber dust which means that it is difficult for bed mites to propagate.
Moreover, BREATHAIR® has excellent anti-bacterial functions as evidenced by BREATHAIR® meeting SEK standards.

As BREATHAIR® is made from polyester-elastomers, even when it burns, the amount of toxic hydrogen cyanide gas released is small.
