Key takeaways
- Single sleepers: A twin or full size, such as 48 by 72 inches, drapes over the body rather than the whole bed, which is how most manufacturers intend it.
- Couples: Weight is by sleeper, not by bed. Two people sharing one blanket usually need a larger size and a weight that suits the lighter person, or two separate blankets.
- Children: Guidance is stricter. Brown Health says a child’s blanket should not exceed ten percent of body weight, should never be used with a child under two, and the child must be able to remove it unaided. Speak to a paediatrician or occupational therapist first.
For most adults who want a glass bead weighted blanket for restless nights, the YnM line suits budget-minded buyers, Gravity suits those who want a gridded design with a washable plush cover, Baloo suits people who prioritise breathable cotton, and a cooling lyocell or bamboo version suits hot sleepers. Whichever you choose, the weight matters more than the brand: the widely quoted rule is about ten percent of body weight, and anyone with a medical condition, and any child, should get professional guidance first. This guide compares the main glass bead options using maker specification pages and independent reviewers, and explains how to size, wash, and judge them.

Why Glass Beads, and What the Trade-Off Is
Weighted blankets use either plastic poly pellets, glass microbeads, or no fill at all (a knit, like the Bearaby Cotton Napper, where the yarn itself carries the weight). Reviewers and fabric writers generally describe glass beads as finer, denser and quieter than plastic pellets, which lets a blanket stay thinner for the same weight. Fine beads also shift less audibly when you turn over, a real point for light sleepers. The trade-offs are that glass-bead liners are often hand-wash only, can feel cool to the touch at first, and are heavy to move and dry.
It is worth stating plainly that a blanket is a comfort product. Sources that discuss research are cautious about promising any effect on sleep problems. If restlessness is persistent, comes with loud snoring, pauses in breathing, pain, or anxiety that affects daily life, speak to a doctor before assuming a blanket is the answer.
At a Glance: Glass Bead Blankets Compared
| Blanket | Best for | Key stated specs | Limits |
|---|---|---|---|
| Gravity Blanket (original) | Buyers wanting a gridded build with a removable plush cover | Listed in 15, 20 and 35 pound weights; the 15 pound twin is listed at 48 by 72 inches; one retailer lists the fill as 91 percent glass and 9 percent polyester fibre | Premium tier; the weighted liner is hand-wash and air-dry only |
| Gravity Cooling (lyocell) | Hot sleepers | Forbes lists a lyocell cover with glass beads in 15 and 20 pounds; the cover is machine washable | Premium tier; inner blanket still hand-wash only |
| YnM Original and Exclusive | Best value and the widest weight range | Seven-layer design; adult 48 by 72 and 60 by 80 inch sizes in 12 to 25 pounds; the maker lists 4.7 inch pockets on the Original and 2 inch pockets on the Exclusive | Less refined finish than premium picks; heavy sizes need a large washer |
| Baloo | Breathable, single-layer cotton | Reviewers describe a 100 percent cotton shell with lead-free glass microbeads in quilted pockets | Mid to premium tier; fewer weight options than YnM |
| Mr. Sandman or RJOP | Entry-level glass bead option | One roundup names a 15 pound queen from Mr. Sandman; other guides call RJOP a genuine glass bead blanket at an entry price | Sourced from affiliate-style roundups; specs vary by listing |
Gravity: The Premium Reference
Gravity is the name most roundups lead with. Forbes Vetted ranked the Gravity Cooling Weighted Blanket best overall and reported that the beads stayed evenly distributed and the blanket stayed relatively quiet overnight. The original is described as an inner weighted blanket filled with fine-grade glass beads, with gridded stitching to hold the beads in place, and a micro-plush duvet cover that can be removed and washed. A medical-supply listing for the product gives the cover as cotton and the filling as 91 percent glass pellets and 9 percent polyester fibre, with a polyester lining. Weights listed are 15, 20 and 35 pounds, with a 25 pound code also appearing at one retailer.
The maker’s guidance is that it should not be used by children under three, or by any person or pet under 50 pounds. The inner liner is hand-wash and air-dry, which many buyers find inconvenient, so the duvet cover is the part you will wash regularly. Prices across roundups vary widely, so treat it as the premium tier.
YnM: Best Value and Widest Range
YnM is the usual value pick. The maker describes a seven-layer system intended to conform to the body, with more glass beads and less fibrefill for temperature regulation, and a three-dimensional stitching method to stop bead leakage. Adult blankets come in 48 by 72 inch and 60 by 80 inch sizes in weights from 12 to 25 pounds, with a 17 pound option available only in the larger size, and larger shared sizes for a king bed. Its own product pages say the Original line has pockets of about 4.7 by 4.7 inches and the newer Exclusive line has 2 by 2 inch pockets. Smaller pockets generally keep beads from pooling, which is the usual complaint with cheaper blankets. One review of a bamboo version gives a different pocket size from the maker, so rely on the specific listing for the model you buy.
Reviewers note that it is less polished than premium picks, and that the heaviest sizes need a large-capacity washer. A cotton cover keeps it approachable for people who have never tried one.
Baloo: Breathable Cotton
Baloo comes up in non-toxic and breathable-focused guides. One review calls it the most breathable traditional bead-filled blanket, built as a single cotton layer with glass microbeads, and a non-toxic materials site picks it as best glass bead because of its lead-free microbeads and quilted cotton shell. Because these are reviewer descriptions rather than a retrieved maker page, buyers who care about specific material certifications should read the label on the exact product.
Cooling Versions for Hot Sleepers
Restless sleep is often a temperature problem. Glass beads conduct heat differently from plastic and many guides suggest cooling covers in lyocell, bamboo viscose or cotton for hot sleepers. Gravity offers a lyocell cooling edition, YnM offers a bamboo line, and Luxome is named as a cooling option in one guide. A cooling cover changes how the surface feels but does not remove the insulating effect of a heavy blanket, so a very warm sleeper may still prefer a lighter weight or a layer swap in summer.
How to Size a Weighted Blanket
The common rule is about ten percent of body weight, with a range from roughly five to twelve percent depending on preference. Casper and others suggest rounding up one to two pounds if you fall between sizes, and YnM suggests ten percent plus one pound. A person weighing 150 pounds is therefore looking at about a 15 pound blanket.
- Single sleepers: A twin or full size, such as 48 by 72 inches, drapes over the body rather than the whole bed, which is how most manufacturers intend it.
- Couples: Weight is by sleeper, not by bed. Two people sharing one blanket usually need a larger size and a weight that suits the lighter person, or two separate blankets.
- Children: Guidance is stricter. Brown Health says a child’s blanket should not exceed ten percent of body weight, should never be used with a child under two, and the child must be able to remove it unaided. Speak to a paediatrician or occupational therapist first.
Safety Notes
Several sources caution that too much weight can restrict movement and may be a concern for people with respiratory or circulatory conditions, including asthma and sleep apnea. Seniors and children may struggle to push a heavy blanket off. Check with a doctor before using one if you have a medical condition, are pregnant, or have mobility limits, and follow the manufacturer’s age and weight limits on the label.
Care and Washing
- Remove the plush or lyocell cover and machine wash it as the label directs.
- Where the inner blanket is hand-wash only, as with the Gravity liner, spot clean or hand wash and air-dry flat. Wet glass beads are heavy and can strain a washer.
- Heavy blankets of 20 pounds or more may need a commercial-capacity machine, according to reviewers of YnM.
- Check seams and stitching occasionally for bead leakage and stop using a damaged blanket.

Frequently Asked Questions
How heavy should a glass bead weighted blanket be?
The widely quoted guide is about ten percent of your body weight, with some sources allowing one or two pounds extra. Lighter sleepers or those new to the feel often start toward the lower end.
Are glass beads safe?
Makers describe the beads as fine, enclosed in stitched pockets. The risk to watch is a torn seam that lets beads escape, so inspect the blanket regularly and keep it away from children and pets if it is damaged.
Can I wash a glass bead weighted blanket?
Usually the cover can be machine washed, but the inner liner may be hand wash only, as with the Gravity original. Always follow the label for your model, and expect long drying times.
Will it help with insomnia or anxiety?
Treat it as a comfort item, not a treatment. Reviewers describe a calming feel, but persistent sleep problems or anxiety are a reason to see a doctor.
Is a weighted blanket suitable for children?
Only with professional advice. Guidance from health sources is that it must be well under ten percent of body weight, never used with a very young child, and always removable by the child alone.
What size should I buy for a double bed?
Weight is chosen per person. A couple sharing one blanket often needs a larger size such as the 80 by 87 inch option YnM lists, but many couples prefer one blanket each so each sleeper has the right weight.
