What is a Weighted Blanket Made Of | Materials and Design

March 18,2024

A weighted blanket is a sleep aid and relaxation tool designed to mimic the sensation of being held or hugged. Constructed from various materials, these therapeutic blankets aim to provide gentle pressure across the body, which can assist in alleviating anxiety, stress, and insomnia. This deep-pressure stimulation, often likened to a firm hug, may enhance the production of serotonin, a neurotransmitter that promotes calm and well-being.


The inner layer of a weighted blanket typically contains materials like fine-grade glass beads or poly pellets, which add weight in a uniform manner. The choice of fabric for the outer cover includes options such as cotton, minky, or a blend of cotton and polyester, catering to different tactile preferences and climates. A key consideration in the design is the blanket's ability to distribute weight evenly, ensuring a consistent calming effect that may benefit individuals with sensory processing disorders, such as autism.

The potential health benefits of weighted blankets have garnered attention in the wellness community. By potentially lowering cortisol levels, the body's stress hormone, and promoting relaxation, these sleep products could contribute positively to mental health and offer an alternative or supplement to traditional sleep and anxiety treatments. Their use has become more widespread as more people seek non-pharmacological options to improve their quality of sleep and overall emotional balance.

Weighted Blanket Materials and Design


Understanding the various materials and design elements of weighted blankets is crucial for selecting a blanket that provides comfort and support. From fabric choices to the types of fillers used, these aspects significantly influence the blanket's feel, effectiveness, and maintenance.

Fabric Types and Choices

Fabric is a key component that determines the feel and durability of a weighted blanket. Common choices includecotton for its breathability,flannel andfleece for warmth, andmicrofiber for a soft texture.Bamboo andlinen offer natural hypoallergenic properties, whileminky fabric is favored for its plush feel. For eco-conscious consumers,organic cotton andrayon derived from sustainable sources are popular options.

Inner Fillings and Weights

Thefiller of a weighted blanket adds the necessary weight for therapeutic benefits. Materials likeglass beads,plastic pellets, andmicro glass beads are commonly used.Steel shot beads provide high density in smaller volumes, whilesand is less common due to the risk of leakage and lower durability.Organic, non-toxic fillers align with eco-friendly preferences and ensure the blanket ishealthy for the user.

Weight and Weight Distribution

A key feature of weighted blankets is theeven weight distribution across the user's body, made possible by uniformcompartments within the blanket. Theinner weight of a blanket is generally guided by personal preferences and body weight, often ranging from 5 to 30 pounds. Properdensity andweight are critical for maximizing the potential benefits, including increasedserotonin production and enhanced sleep quality.

Additional Features and Considerations

Additional features such asduvet covers—preferablyremovable andmachine washable—extend the blanket's durability and ease of care.Hypoallergenic materials cater to those withallergies, while options forbreathability are important for temperature regulation.Weighted blanket materials andconstruction vary, with some designed for therapeutic support and others for general comfort.

DIY Weighted Blanket Options

For those inclined to craft their own solutions,DIY weighted blanket options offer a personalized experience. Materials includecotton orpolyester fabrics and fillings likeglass beads orplastic poly pellets. The construction process involves creatingsquares orcompartments to keep the filling in place, ensuring consistentweight distribution according topersonal preferences and desiredblanket weight.

Health and Therapeutic Benefits


Weighted blankets are designed to offer a range of health and therapeutic benefits, primarily through the application of even pressure to the body. This section discusses how they impact physical and mental health, improve sleep quality, and support therapy for specific health conditions.

Physical and Mental Health Impact

Weighted blankets applydeep pressure stimulation, which can mimic the sensation of being held or hugged. This pressure aims to increase the production ofserotonin, a mood-boosting hormone, and reducecortisol, a hormone associated with stress. Many individuals, including those withsensitivities or certain medical conditions such asADHD andsensory processing disorders, may find comfort and a sense of calm, contributing to diminishedanxiety andstress.

Improving Sleep Quality and Patterns

The use of weighted blankets can also enhance sleep quality. The distribution of weight across the blanket may promoterelaxation and help toreduce anxiety at bedtime, which is beneficial for people suffering frominsomnia orrestless leg syndrome. The increasedserotonin production, along with the stimulation ofmelatonin production, helps to regulate sleep cycles, assisting individuals in achieving a more restful night's sleep.

Use in Therapeutic Settings

In therapeutic settings, weighted blankets are often utilized for thecalming effect they provide. They are particularly helpful for individuals on theautism spectrum, as well as those withPTSD ordepression, where the need tocalm thenervous system is crucial. This approach, known asdeep pressure stimulation, is recognized for its effectiveness in creating a sense of security and reducing symptoms associated with these conditions. The overall comfort provided by the weight can contribute significantly to the management and treatment of thesehealth conditions.
