Ok, but not great
The version that has the flat bit in the middle is preferrable to me for sleeping. The large foam roller one was not comfy or easy to use for me. I did get a decent curl, but honestly I think I just prefer the sock method for sleeping. I think if you showered in the morning and then were able to use this while you were awke and doing chores or reading it would be better. I didn't overly enjoy sleeping with this.
