From the first night after letting the bed rest for  5 days I've  slept the best I have in years. The first night was good and it's gotten better and better. Like sinking into a cloud with good support,  no more waking up with sore spots. We did have an oder while letting the bed rest,  not a chemical smell , more like hay or burlap. We still get this oder for a brief second, but with less frequency . Im sure over time this will disappear. The only problem I am having is getting out of bed in the morning, I'm oversleeping more than ever.
