For product itself ...
The material feels like to unpack an oversized bow Bastelfilz, and feels like that.
After the first wash but (which you should definitely make before the first Verwenung also) flies the impression that the fabric feels very good, is very valuable and well-made, crackling or rustling respect nothing.
Class and the semi-circular zipper (one long and one short side), which makes it possible to relate the mattress alone without help with the slipcover.
Tip: mattress upend against a wall and opened fully reflect the reference side from top to bottom and in one direction, zero problem with my 160x200er the reference was in 2 minutes on it.
But beware !!
Who uses a mattress with a fixed useful side, should definitely remember where after relating the sleeping side.
A tip for the manufacturers: a simple marker, perhaps in the form of an arrow on an inconspicuous area can as much help, I have resorted to me thus, an arrow and the marker to write "up" with a felt pen on the side edge.
Given the price quite recommendable, but legally dubious because of withdrawal exclusion.
Can this be resolved satisfactorily for the client side, there's the 5th star.
