Compare the Cool Side Pillowcase with standard cotton to see which truly helps hot sleepers. Learn the trade-offs and find your best match.
Quick answer
For most hot sleepers, the Cool Side Pillowcase is the better choice because its Lulltra™ Cool technology actively maintains a cool-to-the-touch surface, whereas standard cotton only feels cool initially and can trap heat.
Why standard cotton falls short for hot sleepers
Standard cotton is breathable and affordable, but it doesn't actively regulate temperature. It absorbs moisture and can feel warm and damp by morning, especially for those who experience night sweats.
The Cool Side Pillowcase uses Lulltra™ Cool technology to help regulate body temperature, maintaining a cool-to-the-touch surface all night. This is a key difference for anyone who wakes up flipping their pillow to find the cool side.
Comfort and fit considerations
The Cool Side Pillowcase is designed specifically for The Original Adjustable Toddler Pillow, measuring 13 x 19 inches. If you have a standard adult pillow, this case won't fit, so check your pillow size before buying.
Standard cotton pillowcases come in many sizes and are widely available, but they lack the specialized cooling technology. If you prioritize a universal fit over cooling performance, cotton might be more practical.
