The Ecrin Superior Pyrenex mattress topper is ideally recommended to accompany you through your nights if you are looking for firm support without pressure points on top of your existing mattress. At 4 cm thick, this mattress topper is perfect for complementing a mattress that is too soft or too plush. With its retaining elastic straps, it will stay perfectly in place, and it is ideal for couples, as the natural filling allows for good individual distribution of comfort.
