The support I have now a couple of weeks into use.
The delivery arrived promptly - execution properly.
I can only confirm the ratings! They bent over it the first time and "ahhhhhhhh" sinks into his new Wölckchen.
Unpleasant smell, I also perceived very briefly.
After a few weeks but would love myself opted for the harder version. The H2 is very soft.
And it should be mentioned that there are definitely warmer than without Topper! Namely've after the first night my same winter exchanged for my summer bed!
Otherwise, it sleeps up wonderfully! Can I highly recommend each. Have bought the topper also because of my shoulder and back pain.
From me strong buy recommendation.
One star deduction I give because of heat generation - and because it is a bit too soft.
