A signature experience

Our Sommio Cocoon combines either a standard or prime weighted blanket in a plush cover, available for quick delivery. The double sided cover has a luxurious plush furry fabric and a textured velvet; providing fantastic tactile stimulation (we don't use cheap microfibre "minky") . The weighted inner is hand sewn. The 12 ties around the cover and blanket pair the two together, ensuring the blanket stays in perfect position inside the cover.

How does the Cocoon weighted blanket help?

Our weighted products are effective therapeutic aids, helping people suffering from stress, anxiety and insomnia.

The weight, pressure and embracing effect help to enhance body awareness, provide a calming sensation and prompt your body to release hormones which have an anxiety-reducing and calming effect both mentally and physically. Greater body awareness reduces tension levels in the body, and this in turn improves breathing and increases the sense of calm.

The Sommio Cocoon blanket helps you:

  • Achieve greater calm
  • Get better sleep
  • Improve body awareness
  • Improve attention and focus
  • Fall asleep faster

Hand Sewn

All our products are hand sewn by workers who are paid a fair wage, and quality tested to make sure they match up to our high standards. Each blanket is seperated into a grid of individually filled pockets ensuring weight is distributed evenly.

Quality Cotton

Many manufacturers choose to cut costs by using a blended fabric or cheaper Polyester, our blankets are made out of 100% European cotton, selected to blend comfort and durability to create a blanket you'll love, and a blanket which is made to last.

We've made the switch from plastic to glass filling, in a concious move away from materials which have been shown to be harmful to wildlife and the environment. These glass microspheres are hypoallergenic and are suitable for even the most sensitive sleepers.

Choosing your weight

We recommend that you choose a blanket which is between 10-15% of your body weight for maximum therapeutic benefit. Use the slider below to get our recommendation for you:

The best weight blanket for you is:

7 kg


What are the dimensions of Cocoon weighted blanket?

Our Cocoon weighted blanket is 135x200 cm in 5, 7, 9, and 11 kg variants.

What's the difference between prime and standard pockets?

Our blankets use a grid of pockets to keep the weight in place inside the blanket

The Prime pocket option is more expensive as there is a lot more work in creating each blanket, the smaller pockets keep the weighted fill much better distributed - which creates a more effective blanket and our best weighted blanket experience.

Our standard pocket size is 15 x 20 cm, our Prime pocket size is 10 x 15 cm; so on an adult medium blanket, there are 100 Standard pockets, or 169 Prime pockets.

Can I go for the heavier weight?

We've found the blanket is most comfortable and effective at around 10% - 15% of your body weight, but if you feel you'd like to go heavier or lighter then go for it!

Are these any good for meditation?

We love it, and we've had a lot of good feedback about using the blanket for meditation so we'll say yes!

Is the blanket machine washable?

These plush outer and weighted inner are both machine washable, but the wighted inner may be too heavy for some washing machines, so make sure you know the maximum load weight for you machine before adding you blanket to the wash.

Can my partner and I share a single Cocoon blanket?

We've found that to maximise the effectiveness of the blanket it is best used for only one person; however you can still experience the comforting sensation whilst sharing.

Can these be used with a duvet cover?

We recommend only using the Cocoon weighted blanket with the provided cover, the blanket and cover tie together to make sure the weighted inner stays in place; it's common for weighted blankets to bunch inside a standard cover.
