Best for Pressure Relief
Honeydew Scrumptious Cooling Side Sleeping Pillow
Pros
Offers pressure relief
Designed especially for side sleepers
Adjustable and cooling
Cons
Pricey
The Honeydew Scrumptious Cooling Side Sleeping pillow is made with CertiPUR-US certified foam, which is one of the best fill materials for pressure relief. Besides the material, the pillow’s C shape keeps your body in alignment while you're sleeping on your side.
“Contoured pillows feature a curved shape designed to cradle the head and neck, providing additional support and alleviating pressure points,” Dr. Ormond explains. Besides its supportive style, this pillow’s cooling properties shine. The memory foam is made with a copper base (rather than a gel base), which keeps the pillow from running too warm.
Plus, since the fill is adjustable, you can easily customize the pillow to fit your preference. We found this pillow very firm initially until we took out some of the fill. Unless you like a very soft pillow (such as a true down pillow), this pillow will likely work for you because it’s so customizable.
This brand seems to run a lot of sales, so keep your eyes peeled for savings around holidays, Black Friday, or Cyber Monday. Or, if you want to get it now (but it’s not in your budget), the brand offers Affirm for payment in installments.
