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

I left the topper exactly 72 hours as intended. I slept on it the second night, it's not memory foam. The upper mattress does not adjust to the shape of the body. I woke up still with pain in my shoulders and hips. Also, I bought a 3" but it's more like a 2-1/2 or 2-3/4". I bought a 4 inch topper at Walmart 10 years ago, it wasn't memory foam. but it was more comfortable than this. Sorry Avenco. First, Avenco keeps you cool. Where one of Walmart got really hot. I would happily spend more and get something better. But the reviews were so positive that I took a chance :( Now that I've used it twice, I'm not complaining, I'm sending it back. Sad day.
