What's wrong with beads?

Beads always bunch

Weighted blankets work on the principle of deep touch pressure, which requires an even pressure over a large area, loose beads will always group and fall to the lowest point.

This bunching not only makes the blanket ineffective, but causes the blanket to bunch inside a cover; requiring tabs and ties to attach it to specialist covers.

Because Weightex has the weight integrated into the fabric, as the fabric forms around the body so does the weight; providing perfect even pressure.


Weight is integrated into fabric for zero movement

Weight is distributed evenly

Weight is fixed in place so cannot leak

Breathable, so doesn't trap heat.

Glass Beads

Loose fill, needs to be contained in pockets, still moves around

Beads bunch at lowest point

Padding is required to stop beads sloshing around.

Beads wear at seams and eventually leak

Blanket Overview


Medical research has shown that deep pressure stimulation: an even gentle pressure applied across the body, triggers the production of serotonin, often referred to as the happy hormone; whist simultaneously reducing levels of cortison (the stress hormone) and boosting levels of melatonin, helping you achieve a deep calm.

This calm state leads to deeper sleep cycles, helping you to achieve satisfying rest and wake up feeling fresh and revitalised.

Care Instructions

Our weighted duvets fit inside a standard single duvet cover, we recommend washing the cover rather than the duvet for the longevity of your item.


Our weighted duvet is designed for a single person and comes in 2 different weights:

  • 8 kg | 17 lbs

  • 10 kg | 20 lbs

Your duvet should be roughly 10% - 15% of your body weight (i.e 60 kg body weight = 8 kg blanket).

If you're between weights, we recommend you go with the heavier weight. For example an 90 kg user would be best suited to a 10 kg blanket.

The Duvet comes in two different thicknesses:

  • Light - Perfect for hotter sleepers, equivalent to 2-5 tog

  • Medium - A great all rounder, equivalent to 5-8 tog

 Since our duvets are made by hand, there may be a small variation in weight. They measure 135 x 200 cm.
