I ordered this topper based on EXCELLENT reviews, to see if it would help my back pain. We've had a sleep Number mattress for 6 years but the pillow top and foam on it was starting to wear down. We purchased the 4" Visco topper to replace the existing foam in our mattress top. I was waking up in severe rib / torso pain (and have been seeing a chiro for 4 years for misc issues). We had a memory foam bed while traveling in Italy recently and I woke up without pain! So we ordered this topper; unfortunately for some reason, it has worsened my pain. It's very soft and comfy but does not provide as much support as I expected.
