I've had this topper for several months. Loved it at first, but it now seems to have a permanent sag in the middle (deepest around where my hips land, and spreading outward from there), and I weigh all of 125 pounds. Pretty sure the topper is Dunlop-processed latex, which could be fine in a higher ILD, but this topper appears to be too low a density for me. (The processing method and ILD were not specified on this site or on the package; I took a chance and bought the topper based on the many positive reviews here.) The permanent compression in the middle is really disappointing. Looks like I need a higher-ILD latex, maybe Talalay-processed, and I need to know exactly what I'm buying.
