How they work

Groundd weighted blankets are weighted with hypoallergenic natural glass sand. The glass sand is held silently in place in microfiber pockets stitched throughout the blanket to ensure they are secure and that the weight is distributed evenly. 

Laying under evenly distributed weight is incredibly comforting. It is similar to the calming sensation of an embracing hug, being swaddled, or a protective cocoon.  The soothing pressure signals to your body that you are safe, it puts your mind at ease and promotes deep restful sleep. 

Groundd weighted blankets are constructed with high quality natural materials that feel soft and light on your skin to ensure the heavy blanket is as cool and breathable as possible. 

Deep Touch Pressure (DTP) is a tactile sensory input from any form of pressure exerted equally across the body, such as a hug, swaddle, or in this case, a weighted blanket. Receptors in your skin detect this grounding pressure and send a signal to your brain that you are in a stable safe environment. Your brain then releases serotonin & melatonin (feel-good relaxation neurotransmitters) while cortisol (stress & fight or flight hormone) is inhibited. This calming effect eases tension in our mind and allows us to fall asleep and remain asleep. 

The science behind weighted blankets and improved sleep is supported by peer reviewed research, here are a few of the research articles we've found most informative:

Exploring the Safety and Therapeutic Effects of Deep Pressure Stimulation Using a Weighted Blanket.

Positive Effects of a Weighted Blanket on Insomnia.

Asides from Insomnia, weighted blankets have been found to be highly effective in managing symptoms of a wide range of conditions. 

Anxiety - DTP has been shown to produce a calming, soothing effect that reduces anxiety. In studies, researchers have observed that weighted blanket therapy lowers blood pressure, reduces pulse rates and helps 63 percent of study participants feel less anxious.

ADHD - deep touch pressure also helps with mood and sleep, so weighted blankets are also great for addressing those symptoms in ADHD sufferers.

Restless Leg Syndrome - Weighted Blankets have been found to be effective for reducing the symptoms of Restless Leg Syndrome by constantly applying pressure on patients legs.

Fibromyalgia Pain - For some patients, the gentle but firm pressure of a weighted blanket is an important tool for preventing fibro flare-ups.

PTSD - Weighted blanked have been found to be effective in treating PTSD by reducing the symptoms of insomnia and anxiety caused by the condition. 

OCD - OCD has been linked to low serotonin levels. By using deep touch pressure therapy, weighted blankets may help boost serotonin and ease the severity of OCD.   

Autism - According to Harvard researchers, “one therapy that has mounting evidence of support is massage or touch therapy.” In studies, autism patients responded most favourably to gentler, slower touch. Additionally, researchers found: “Touch therapy has been noted to have immediate and long-term effects on the body’s biochemistry, including decreased levels of the stress hormone cortisol, and increased levels of the neurotransmitters serotonin and dopamine, which play roles in mood regulation, movement, impulse control, and more.”   

Sensory Processing Disorder: Weighted blankets can help patients manage a possible symptom of sensory processing disorder of being oversensitive to things in their environment.  

- Groundd Weighted Blankets are scientifically designed for optimal sleep, delivering the maximum benefits of sleeping under weight without the inadequacies of traditional weighted blankets.

- Our design utilises premium breathable fabrics and air channels inside our weighted blankets to keep air circulating and maintain a comfortable sleeping temperature.

- Instead of using noisy plastic poly beads, Groundd uses a natural glass sand to add evenly distributed weight completely silently.

- Groundd believes in a holistic approach to wellbeing that does not only optimise your wellbeing but the planet's wellbeing. This is why we use sustainable organic materials and reusable packaging made from recycled materials.

Traditional weighted blankets (and bedding for that matter) is known to trap body heat, causing overheating and discomfort. 

Groundd weighted blankets have been specifically designed with hot sleepers in mind.

Our blanket is constructed with high quality breathable layers of soft organic cotton on the outer layers and air channels on the inner layers to dissipate body heat when sleeping, not trap it.  The fine glass beads inside the blanket do not retain heat, unlike others filled with plastic beads. 

Our weighted blanket covers are made out of ultra-breathable & 100% natural bamboo lyocell fabric. This fabric naturally absorbs body heat and wicks away moisture, making it the absolute best choice for hot sleepers. 

Note: Although the cover is ultra-breathable it does still add two additional layers so if you are a hot sleeper, you may wish to sleep without the cover during the warmer months. 

The cover has a full side opening with a zipper. This allows for wide open access to the interior of the cover where there are 8 ties to attach to the blanket. 

1. Open zip & flip the cover inside out and lay it flat on the floor or bed.

2 Lay the blanket out on top of the cover, and tie all the pieces together.

3. Turn the cover the right-side-out and voilà your weighted blanket will be perfectly aligned inside the cover and anchored in place. 

No, the weighted blanket is very comfortable to use by itself without the cover with it soft organic cotton exterior. You may wish to leave the cover off during the warmer months as it does add some heat. 

It is better for the longevity of the weighted blanket to wash the cover instead of the blanket itself but the weighted blanket can still be machine washed. Please see care instructions. 

Sizing, Weight and Care Instructions

122cm width x 200cm length

Weighted blankets are designed to provide even weight distribution over your body, not over your bed.

Unlike a normal duvet, the blanket is not meant to cover the whole width of your bed. Groundd blanket sizes are thoughtfully designed to generously cover your body providing maximum benefits of the weighted blanket. 

If you share a bed with your partner and both want to use weighted blankets, see the next question.  

Sharing is caring...except when sleeping!

When sleeping with your weighted blanket, the weight needs to be evenly distributed over your entire body to create the calming effects of Deep Touch Pressure (DTP). When spreading one larger blanket over two people, DTP is interrupted as the weight is unevenly dispersed over two bodies & redundant bed space. 

Also, let's face it, are you really going to miss your partner stealing your blanket in the middle of the night?? 

Our weighted blanket is purposefully designed to generously fit your body to get the benefits of Deep Touch Pressure therapy and optimise your sleep.

If we were to offer the blanket in larger sizes too much weight would lie redundantly on the flat of the bed or over the edges minimising the sleep benefits and when it comes to good sleep we refuse to compromise!

It is best to spot clean the weighted blanket but it is machine washable. Wash separately in delicate/gentle cycle in warm water. Hang weighted blanket to dry.

Do not iron, tumble dry or dry clean

We recommend washing cover before first use.  

Wash separately in delicate/gentle cycle in warm water (30°C)

If possible line dry, otherwise tumble dry on gentle setting. Remove from tumble dryer immediately to avoid crinkles.

Bamboo Lyocell de-wrinkles itself naturally over time but should you need to accelerate this process iron on a light setting.

As this is an entirely natural product, slight pilling is not unusual with initial use of bamboo lyocell. This can be reduced or removed by following care instructions. Slight pilling is normal for natural fibres, especially in response to friction and isn't a fault or defect.

Avoid prolonged exposure to direct sun light.

Do not bleach

Materials and Sustainability

Outer layer: 100% organic cotton.

Filled with BPA and lead free glass beads within a thin microfibre polyester layer to protect and prevent beads from pooling.

OEKO-TEX certified for chemical safety. For more information about what this means, see  question below. 

The cover is made from 100% organic Bamboo Lyocell. This silky smooth fabric is as light as a feather against your skin, is highly breathable and is moisture wicking. The fabric is also naturally durable, antibacterial and anti fungal. These properties makes it the ideal fabric to sleep with, including for hot sleepers.

The fabric is not only ultra functional & comfortable to sleep with but unlike most bamboo fabrics, which are usually produced using the viscose method, bamboo lyocell is produced using a closed-loop system making it completely eco-friendly. See the next question for more details on how this innovative material is so sustainable.

The covers come in our Glacier colour, which is a soft grey blue with a lustrous finish and a calming tone.

The cover is also OEKO-TEX certified for chemical safety.

Bamboo is an incredible plant in its raw form. It is highly renewable, able to regrow to its full adult size in 3-5 years, growing up to 2 feet in 1 day. It is naturally pest resistant, meaning that no nasty pesticides are required to grow it and its planting helps rebuild eroded soil. On top of this the bamboo plant requires far less water, absorbs 5 times more carbon dioxide and produces 35% more oxygen than similar plants such as cotton.

Although the plant itself is incredibly sustainable, when it comes to the way that bamboo is mostly processed into fabric using the viscose method, the overall environmental benefits are completely over weighed. To produce bamboo viscose, the material must go through an intense chemical process involving the use of harsh chemicals such as sulfuric acid and sodium hydroxide. These chemicals are extremely harmful to the environment and people in general. Not only do they negatively affect the quality of the once-natural material, but chemical runoff from whoever manufactured the fabric is detrimental to local environments.

Unlike Bamboo Viscose, Bamboo Lyocell is a 100% eco-friendly fabric as it is processed out of bamboo using an innovative closed-loop system. This means that 99.5% of inputs are captured and reused in continuous processing. This technology results in a final textile that is highly sustainable, producing almost zero waste and is completely biodegradable. 

It means that every component used in a Groundd product (every thread, textile, label, zip & tie) is free of harmful chemicals and other substances and is therefore 100% safe in human ecological terms. All products are tested by Independent OEKO-TEX certified partners. For more information see here.

Groundd is committed to only using recycled raw materials in our packaging.

Apart from the recycled plastic handles we are completely plastic free.

Our weighted blanket & weighted blanket cover both come in re-usable premium cotton bags.

These cotton bags are packaged in our recycled cardboard shipping boxes for delivery.
