I’m a big fan of this wedge pillow. It’s great for sitting up in bed, and I’ve never had anything better for under my knees. I love it so much I actually bought two. It’s also very ergonomic for other..activities, if you catch my drift. Makes it much more comfortable.
Amazon would be best. I have this one.
