Zur Matte itself: Since the mat is 1.5 cm thick, it advertises itself wonderfully for exercises, both standing and kneeling, or lying.
Even people with problems are burdening her knees on "hard" substrates of this mat have a lot of fun, because it is actually quite soft and some takes pressure of the joints. At the same time the state will remain on the mat yet safe and not bagged away or loses his balance by the soft ground.
The mat remains when it is rolled out are also flat and will not start, for example, at the end again to roll up by itself, as known eg from cheap mattresses.
As stated above, you can smell the mat only with "direct nose contact". ;-)
But then she smells just after foam etc. and not somehow chemically - that should be normal.
The mat also takes on the load again their old form of, so that if you leave a long time in one place his hands or feet, footprints disappear after a short time.
We are very pleased with the product and can recommend it for that price anyway. Strong buy recommendation!
Addendum 03.25.2014: After nearly a year in use (2-3 times a week) you can see some marks on the mat, the marks do not disappear so quickly and some places remain even for some time after prolonged exertion of pressure "dellig". But hey, for the price you can then sometime sometimes think about a new. ;)
