Extra Firm Mattress Topper Queen Size, 3 Inch Firm High Density Memory Foam Bed Topper for Back Pain Relief, Gel Bamboo Charcoal Infused Cooling Mattress, CertiPUR-US Certified, Washable Cover

I just got this one Today. I have a Tempedic mattress that’s getting too soft. Wanted more firmness for my lower back and hip pain. I bought because of reviews and Prime return. 3” no smell It’s already near 3” We will see. Laid on it seems firm—better than my mattress. https://www.amazon.com/Grbsy-Mattress-Charcoal-CertiPUR-US-Certified/dp/B0GY89LWM4
