Is certainly also of person to person how to feel the sun characteristics, depending on body weight, height, etc .. Anyway, I was brave and ordered me this Matratze.Anfänglich I found sleeping on her pretty hard ('m 1,55cm and 55 kg) , which in the spring mattress was not the case, since one rather a decreased. It took about 3 weeks to my back to the new cold foam mattress had become accustomed. Since then, I sleep sleep tight like a baby with no back problems and am glad to have bought this mattress. I can recommend it like ...... what but everyone should try out individually for themselves.
