Review on Avenco 3 Inch Queen Mattress Topper – Memory Foam with Removable Cover, Reversible Medium Firmness – Comfort CertiPUR-US Foam for Queen Beds by Whitney Starvaggi

This foam is ideal for those who weigh less than 75 pounds. Besides, it's like it doesn't exist. I wanted to replace a 20 year old 2.5 inch memory foam pillow in the guest room but it is less than effective. It just flattens out right away. I let it expand for 24 hours (I know it takes "up to" 72 hours). to reach full height), but it won't magically transform into a support pillow for the next 2 days. I'll be sure to update when this happens. And I'll wait until then to get it back, so there's no question. I have purchased several mattresses and mattress pads over the years and after the first 24 hours it is what it is. I bought this based on vaguely positive reviews. Now I realize that they had no comparisons or details. If anything changes I'll update here... but otherwise it'll come back. :( Update: I slept on it a few nights, it's not enough. I think 3" might be better. Maybe my expectations were too high for what a 2" foam topper can do. Sleeping on it is not that bad I thought originally.But it doesn't suit my needs.Fitted sheets so the top is a bit tight and I don't fall in the water that often.But I can still say it's all just collapsing under the heaviest parts of me.Under the Stroke better than nothing, but I need 3 inches thicker foam.
