Hello, I got my husband the dark green set for his birthday. It was a total surprise - he had not been shopping for any product like this. He has some back pain, and I thought this might help. He loves it! He finds it very relaxing and will actually fall asleep on the floor laying on it. He liked it so much, he ordered one for his dad's birthday, as his dad also has some back pain. We got the set with the pillow. When I'm laying on it, I don't use the pillow, but he likes it. That part is probably personal preference.
