very satisfied. I needed a quick solution to soften a too firm mattress (new, it is semi-firm latex) since because of my cervical spondylosis my nights were too painful.

It does not remove the firmness and support of the mattress but softens the pressure points. By cons it is a pity that the manufacturer does not provide several different heights because my choice was 5cm if that had been possible. I also met the following quality / price ratio
