CosySan® und SoftyFil® duvets

An "Haute Couture" product among the synthetic bedding fillings.
The snowflake-soft 4-hole fiber balls (4-hole 3D) offer a super moisture exchange (up to 4 times more than 1-hole fiber balls)

The ARO® sleep laboratory has developed these cassette covers (construction and covers such as downstairs) into an airy and lightweight product for pleasure-seeking sleepers that do not require down or natural fiber fillings.

The fiber-filled ARO® bedding is light and yet cuddly.
The cover is made of fine 100% cotton inserts.

Why are CosySan® fiber balls better than "normal" fiber fillings?
CosySan® - is the high-tech hollow fiber ball for restful sleep. The snowflake-soft 4-hole fiber balls (4-hole 3D) offer a super moisture exchange (up to 4 times more than 1-hole fiber balls) and a very great breathing activity.
CosySan® sleep comfort means: improved heat and humidity regulation, maximum dimensional stability and an extremely high cuddling factor:
Vital sleeping pleasure in abundance
