After all sorts of other previously, we opted this time for the bath mat from Ikea. She quickly came delivered via Amazon to us, unpacked - and the breath caught ... 4 days needed (despite use at the time) to its pungent odor to get rid of. Despite cleaned regularly after showering / bathing and drying as described in the instructions made repeatedly a biofilm, of not going away, despite the washing according to the instructions in the machine and only by regularly scrubbing as with other mats also went away. Ultimately, it does what it is intended, therefore, the three stars - it has a good anti-slip effect and sucks good.
