Choosing a weighted blanket isn’t just about comfort, it’s about effectiveness. The wrong weight, size, or fabric can leave you overheated, restless, or unsupported. That defeats the entire purpose of deep pressure therapy.

At Mosaic Weighted Blankets, we’ve spent more than a decade helping people find their calm. Whether you’re navigating sensory overload, struggling with sleep, or simply looking for better nightly routines, this guide will help you choose a weighted blanket that truly works for your body, your needs, and your life.

How Much Should Your Weighted Blanket Weigh?

The most common guideline is the “10% rule”: choose a blanket that weighs roughly 10 percent of your body weight. But that’s just a starting point.

Mosaic’s Recommendation: Start Lighter

From years of customer feedback, we’ve found that most people adjust better to a slightly lighter weight at first. A 120-pound adult, for example, might start with a 10- or 12-pound blanket, not jump straight to 15. The same principle applies to kids, older adults, and anyone new to weighted blankets.

It’s easier to step up in weight than to struggle with one that feels too intense.

Key Factors for Weighted Blanket Weight

  • Sensory seekers may prefer more weight (up to 12–15 percent of body weight)

  • Sensory avoiders or anxious users often benefit from a gentler pressure (8–10 percent)

  • Hot sleepers or those with joint sensitivity may want to go lighter to avoid discomfort

A well-weighted blanket should feel grounding, not overwhelming. If you feel restricted or tense under it, it’s probably too heavy.

What Blanket Size Should You Get?

Size matters, not just for your bed, but for how the weight is distributed across your body. Here’s how we guide customers:


Blanket Size

Best For

Notes

Child

Kids under 80 lbs

36x50 inches, sized to stay in place

Throw

Adults under 130 lbs or travel use

Great for laps, chairs, and small beds

Twin

Most solo sleepers

Our most popular adult size

Full

Larger adults or more bed coverage

More surface area, same DPS effect

King

One adult only

Not for sharing—DPS works best when weight is focused on one body


Why Not Share a Weighted Blanket?

Because the weight spreads out, reducing its effectiveness. The blanket may not feel heavy enough for either person, and it can bunch, pull, or shift during the night. For couples, we recommend separate blankets tailored to each person’s weight and fabric needs.

Sleep Position and Blanket Style

Your sleep position affects how the blanket feels. Here’s what to keep in mind:

  • Side Sleepers often prefer lighter weights to avoid pressure on hips or shoulders

  • Back Sleepers can typically handle moderate to heavier weights comfortably

    Stomach Sleepers should use extreme caution a lighter blanket orlap-style throw is safer to avoid chest compression during sleep

Not sure which category you fall into? Go lighter at first. It’s always easier to upgrade once you know what works.

Choosing the Right Fabric for Your Sleep Style

Fabric isn’t just about comfort, it determines how breathable and temperature-regulating your blanket will be.

Our Recommendations:

  • 100% Cotton – Soft, breathable, and durable. Ideal for most users.

  • Coolmax® – Advanced moisture-wicking tech for hot sleepers or warm climates.

  • Minky – Plush, warm, and textured. Great for cold sleepers or sensory seekers.

Pro Tip: If you sleep hot, skipMinky. Cotton orCoolmax will give you the benefits of Deep Pressure Stimulation without trapping heat.

Matching Sensory Needs and Lifestyle

Weighted blankets support more than just sleep. They’re used during the day to stay grounded, regulate emotions, or ease transitions. For neurodivergent individuals, including those withautism, ADHD, or Sensory Processing Disorder (SPD), weighted blankets offer a reliable way to calm the nervous system with predictable, soothing input.

Whether you’re sensory seeking or sensory avoidant, we help you find the weight and fabric that meets your needs without overstimulation.

Important Safety Considerations

Most adults and teens can use a weighted blanket safely, but keep these guidelines in mind:

  • Never use on infants or children under 3

  • Avoid use in people with limited mobility unless they can remove the blanket themselves

  • Talk to your doctor if you have respiratory or circulatory concerns (like asthma, sleep apnea, or blood pressure issues)

Every Mosaic blanket comes with detailed care and use instructions to ensure long-term safety and comfort.

What If You’re Between Sizes?

If you fall between standard weights or size categories, start on the lighter side. Your body will adapt over time, and it’s easier to layer or upgrade than to deal with discomfort or overheating.

Pro Tip: Our customer support team can help you choose a custom configuration that fits your sleep habits, sensory profile, and space. Just reach out and we’ll walk you through it.

Why a Perfect Fit Actually Matters

A weighted blanket is a therapeutic tool, not just bedding. When it fits your body and needs, the effects can be profound:

  • More restful, uninterrupted sleep

  • Calmer transitions between activities or during anxiety

  • Better focus and relaxation, even in the middle of the day

The wrong fit can mean:

  • Feeling trapped or overheated

  • Weight pooling in the wrong areas

  • Disrupted sleep or irritability

At Mosaic, we engineer our blankets withreinforced stitching,grid-aligned fill, andBPA-free poly pellets that don’t shift or clump, so your blanket keeps working the way it’s meant to.

Final Thoughts

Choosing the right weighted blanket is about more than weight. It’s about understanding how your body responds to pressure, how you sleep, and what your nervous system needs to feel safe.

At Mosaic, we help you dial in those details, from personalized weight recommendations to breathable fabrics and handcrafted quality you can feel. Whether you’re buying your first weighted blanket or replacing one that didn’t quite work, we’re here to help you get it right.
