|Yoga mat. Mattress deluxe. Actually, I've got blanket and a sheet on there too when I sleep.|
Second night, six.
Last night, all 8.
Why? Oh, just because I needed a new experiment. :-) I figure I'd give it a go to realign a few imbalances in my body. I haven't used a pillow for a few years and my neck has thanked me for it (business trips are a bit easier that way, we all know the horrors of hotel pillows...). So far, I'm pretty impressed by how my body has adapted to the lack of "support" by a mattress. No neck pain, no back pain. As soon as you let go of the expectation of strain, your body kind of just relaxes into whichever pose you lie in. Interesting!
