Popular Questions

What is a weighted blanket?

A weighted blanket is a high quality blanket proven to aid in sleep. It is a natural sleep product to help with sleep disorders, anxiety, and stress. The weight of the blanket is evenly distributed on your body, creating a feeling of a cosy embrace.

What weight should i choose?

Our recommendation is 8-14% of your body weight. For example, if you weigh 45-70 kg our 7 kg blanket will work well. And if you weigh more than 70 kg than our 9 kg blanket is better.

What is the Sumo weighted blanket made of?

Our weighted blankets are made of a few different components. The outer layer is a soft minky cover that you will want to pet all day! The inner weighted shell is 100% cotton filled with glass beads. Our glass beads are high quality, non-toxic, washer/dryer safe, and pet or kid friendly.

Product Information

Is the Sumo weighted blanket good for two people?

The weighted blanket is ideal for one person. Two people can cuddle under one blanket but we don't recommend it. It is most effective when the blanket is evenly distributed around one persons body. For this reason we've created the Sumo couples bundle.

Is there a certain way I should sleep underneath the blanket?

The blanket works with any sleeping position. Starfish, Stomach Sleeper, Pillow Hugger - we've got you covered! In fact, we encourage sleepers to try different positions under the blanket.

Why is my blanket weight pooling towards the middle?

If your blanket is pooling during use, we recommend checking that the weighted shell is tightly fastened to the duvet. To do this, unzip the duvet and use the ties around the weighted shell to attach it to the duvet.

Why do you use glass beads over plastic pellets?

We prefer using glass beads as they are very smooth and don't have the texture of bumpy plastic pellets. Glass beads provide the same weight with less bulk of plastic pellets. Glass beads are so small that they cannot break, and it makes for a nicer and softer material.
