What it's like to use the Gravity Blanket, a R3,500 weighted blanket that's designed to reduce stress and help you sleep

Avery Hartmans/Business Insider The Gravity Blanket is a weighted blanket that's intended to help you feel less stressed and sleep better. The blanket began as a Kickstarter campaign, which raised more than R65 million. Now, Gravity says the blanket has netted more than R208 million in sales. I tested the blanket - along with Gravity's weighted sleep mask - for a few weeks and got some of the best sleep of my life. The Gravity Blanket helped my mind to stop racing and put me to sleep almost instantly.

When first I got a Gravity Blanket to test out, I had big plans for turning it into a scientific experiment.

I would wear an Apple Watch, I reasoned, to test how my heart rate responded to a weighted blanket. I planned to take notes about my mood and stress levels to measure whether the blanket could actually relax my central nervous system and calm me down.

The problem is, I kept falling asleep.

For anyone who hasn't heard of the Gravity Blanket or weighted blankets in general, think of it like a Thundershirt for humans . The concept behind weighted blankets is that lying underneath constant and evenly distributed pressure will produce a calming and relaxing effect. Studies have shown that weighted vests or blankets can also help those with autism spectrum disorders, ADHD, high anxiety, or insomnia .

But at the most basic level, weighted blankets mostly just feel like a gentle hug.

Gravity's version of the weighted blanket began as a Kickstarter project in 2017. Gravity raised more than $4.7 million (R65 millon) from nearly 24,000 backers to create a plush, single-person blanket that weighs around 7kg.

Now, Gravity says it's sold more than 60,000 weighted blankets, resulting in $15 million in sales. Gravity has now expanded its product lineup to include a weighted sleep mask, a cooling blanket for those who "sleep hot," and more.

I had the chance to test out the original $250 Gravity Blanket and the $30 weighted mask for a few weeks. I offered them up to friends, coworkers, and anyone who was willing to sit with a 20-pound blanket on top of them. For some people, the experience felt strange and uncomfortable. Others described it as "womb-like."

Me? I had some of the best naps of my life.


Size matters

The first and most important thing you need to know about the Gravity Blanket is that it comes in varying weights. The right blanket for you depends on your size, since it should be equivalent to about 10% of your body weight.

Not realising that, I went with the 20-pound (9kg) blanket and after a few weeks of testing, found it to be slightly too heavy for me. For most adults, 20 pounds doesn't seem like that much, but it can be overwhelming when you're lying underneath it (or trying to schlep it home on the subway).

The other thing to know about the blanket is that it's not the size of a full comforter or duvet, and it's not really meant to be shared. It won't replace your bedding - unless maybe you sleep in a twin bed - and it won't cover both you and a partner at the same time.

Plus, at $250, it's one very pricey blanket.
