After buying an expensive mattress (140x200, H3) is not the hoped-for stabilization of the spine brought - as the heavy body parts (such as pool) for sinking a lot and you thus in the morning as "whacked" woke up, the purchase of this product was thus the logical to have as a consequence not expected to dispose of my mattress on the garbage. My first impression after the first few nights: one Topper "H3 fixed ideal" truly the way to go in the direction of "relief" (m) seems to be a strained lumbar vertebrae and an affordable alternative to (allegedly) so praised highly for sleeping comfort "box spring" - beds. When me my (body) feeling does not deceive, the significantly stronger H3 gel foam consistency of Toppers should restore the proper balanced ratio of hardness to the mattress and thus (as it first appears) exert a significantly positive impact on the spine near muscles. In short, I am sometimes really very pleasantly surprised.
