Cozy "Potato Bed" Trend Promises Restful Sleep, Sleep Expert Weighs In

As of November 16th, 2025, a new TikTok trend called the "potato bed" has been gaining popularity as a cozy way to get a great night's sleep. The trend involves creating a nest-like sleep environment by laying out a fitted bedsheet upside down, stuffing the perimeter with thick pillows and blankets, and then filling the middle with more blankets and comforters to get snuggled in.

According to Dr. William Lu, the medical director of Dreem Health, this "fun, cozy take" on the concept of "cocooning" can actually help promote better sleep. The sensation of being "gently surrounded by pillows and blankets" can mimic the effects of a weighted blanket or being cuddled, which can help lower stress hormones like cortisol while boosting serotonin and oxytocin - chemicals that make you feel relaxed and sleepy.

However, Lu did caution that too much warmth may cause disruption to sleep, as the best sleep occurs when the core body temperature drops slightly. Piling on too many layers can "trap heat," making it harder for the body to cool down. He also noted that surrounding yourself with soft pillows could potentially lead to issues with proper spinal alignment over time.

Overall, Lu recommended thinking of the potato bed as a "cozy relaxation ritual" rather than a permanent sleep setup, suggesting it's best used for short naps, wind-downs before bed, or as a warm respite during the colder months. The key is to create a comfortable, calming space that helps the body and mind relax before sleep without going overboard on the layers.
