Great pillow for side-sleepers, to keep things lined up.
Color: Black, Size: With Cover
I didn't actually expect this to be that useful, but it has improved my mornings a lot.
Since I sleep on my side, often times I my knees would be uncomfortable when trying to go to sleep, or my neck would be sore getting up. This pillow gives me a bit of padding, and helps keep my hips and shoulders lined up.
Simple solution, but works great.

Nice Sleeping Partner
Color: Grey
This is a fantastic body pillow. It comes with the cover and is relatively cooler than the bamboo versions. I have slept with this pillow and I am not disappointed with it, unlike my partner on the other side.
