I've been having difficulty sleeping well and decided to try this pillow. The curved part is great for side sleeping, but I use it for all positions. It's very cooling and I'm looking forward to using in the summer months. I love how light it is, but so plush and supportive at the same time. I can't sleep without this pillow anymore. I let my husband try for a few nights and immediately ordered another one! Also it's washable- game changer!
