Mike Grillo invented the Gravity Weighted Blanket after the 2016 election. Grillo wanted to help people with post-election anxiety, and so he designed a blanket that would calm the nervous system through deep pressure touch stimulation. Deep pressure touch stimulation simulates the feeling of being held, which increases melatonin and serotonin production. Melatonin and serotonin are the hormones that create relaxation and decrease the stress hormone, cortisol. This leads to improved sleep, which has several significant benefits. These benefits include increased cognitive performance, improved emotional wellbeing, and better physical health. By improving a person’s ability to fall asleep and stay asleep, brain function improves and cognitive abilities are sharpened. Furthermore, proper sleep decreases paranoia, anxiety, and irritability.
The Gravity Blanket was the first weighted blanket marketed to the public. Before the Gravity Blanket’s introduction, weighted blankets were used solely by the medical community to treat mental disorders like autism and PTSD.
In 2018, the Gravity Blanket was named one of TIME Magazine’s best inventions. In a 2019 study, 72% of participants reported a deeper, more restful sleep during the night, across 1000 nights of sleep. Additionally, 76% of participants said they fell asleep faster.


The Gravity Blanket contains non-toxic glass beads within a gridded pure cotton shell. The grids of the cotton shell keep the pellets evenly distributed while the user sleeps. Additionally, every blanket comes with a removable velboa plush duvet cover that is machine washable. Internal clasps attach to the inner weighted blanket and hold the duvet in place.
The Gravity Blanket comes in a choice of 15 pounds, 20 pounds, and 25 pounds. The company recommends that users choose a weight that is approximately 10 percent of their body weight. The original blanket was designed for only one person, at a size of 72″ x 48″, but the company also offers Queen/King blankets, cooling blankets, and travel-sized blankets.

Gravity Blanket also offers Weighted Sleep Masks, Flannel-Sherpa Weighted Throws, and a Gravity Pillow.
The Weighted Sleep Mask uses the same deep pressure stimulation design as the blanket. It is made out of micro-plush and imitation cashmere and will block out any light.

The Flannel-Sherpa Weighted Throw is made of soft sherpa fabric on one side and a flannel pattern on the other. It’s the same size as the single Gravity Blanket and offers the same benefits but weighs only 10lbs. In contrast to the other Gravity Blankets, the Flannel-Sherpa Throw is one piece and must be hand-washed or spot cleaned.
The Gravity Pillow is queen-sized and is customizable to your desired level of firmness due to its removal shredded memory foam. The pillow is covered by a Bamboo-based pillow cover, which keeps both sides of the pillow fresh.
