The heaviest weighted blankets, and how to tell if heavier is right for you
We research products from makers' specs and health sources; we do not run hands-on tests. Links to Amazon may earn us a commission at no cost to you. How this works.
- 35 lb queen or king bed-size weighted blanket. Best for: Larger adults who want a blanket that covers the whole bed. See options on Amazon
- 25 to 30 lb single-person blanket. Best for: Larger adults who want concentrated pressure on the body. See options on Amazon
- Weighted blanket with removable cover. Best for: Anyone buying 20 lbs or more. See options on Amazon
How heavy weighted blankets get
The Sleep Foundation says most weighted blankets weigh between 5 and 30 lbs, with children's blankets typically 3 to 12 lbs. At the top end, makers offer bed-size options. Gravity's own product page, for example, lists a 35 lb blanket at 90 by 90 inches, sized for queen and king beds, alongside 20 lb and 25 lb options at 48 by 72 inches.
Heavier options exist mainly because larger people need more weight to reach the same proportion of body weight, and because bigger blankets need more fill to cover a bed.
Why a 35 lb blanket may not feel heaviest
What you feel is weight spread over area, not the number on the tag. Using Gravity's listed sizes:
| Blanket | Size | Area | Weight per square foot |
|---|---|---|---|
| 25 lb | 48 x 72 in | 24 sq ft | about 1.04 lb |
| 35 lb | 90 x 90 in | about 56 sq ft | about 0.62 lb |
The 35 lb bed blanket presses down with roughly 40% less weight per square foot than the 25 lb single-person blanket, because much of it drapes over the mattress edges. If you want the most pressure on your body, a smaller blanket close to your size gives more concentrated weight than a huge one. If you share a bed, see our king size weighted blanket guide.
How much is right for you
The Sleep Foundation's rule of thumb is about 10% of body weight, with preferences ranging from 5% to 12%. A few rows from its chart:
| Body weight | Suggested blanket weight |
|---|---|
| 100 to 240 lbs | 10 to 24 lbs |
| 110 to 264 lbs | 11 to 26 lbs |
| 125 to 300 lbs | 12 to 30 lbs |
| 150 to 360 lbs | 15 to 36 lbs |
The Sleep Foundation notes these figures reflect preferences, not an exact science. Research has used weights within this range. In a randomized trial of weighted chain blankets for insomnia in psychiatric outpatients, the blanket was 8 kg (about 17.6 lbs), and 10 participants switched to a 6 kg version. One participant stopped because of anxiety while using the blanket. More on the evidence is in our deep pressure guide.
Who should not go heavy
- Anyone who cannot remove it alone. Do not use a blanket that the person cannot lift off without help. Caregivers should check safety with the person's clinician, particularly for children, older adults and people with disabilities. A blanket should never be used as punishment or restraint.
- Children. Gravity's current FAQ describes its children's model for ages 7 and older and does not recommend the full-size Original for anyone under 50 lbs. The Sleep Foundation advises parents not to rely on the 10% rule for kids, to talk to a family doctor, and to lean toward the lower end.
- People with breathing conditions or sleep apnea. The Sleep Foundation warns that a blanket that is too heavy can restrict airflow and advises talking to a doctor first, as it does for low blood pressure and type 2 diabetes.
- People prone to claustrophobia. Heavy weight may feel trapping rather than calming.
Living with a heavy blanket
Heavy blankets are harder to wash and move. Check your washer's capacity before buying, consider a removable cover, and see how to wash a weighted blanket. Try new weight on your lower body first and build up, and if you wake up stiff, sore or overheated, step down a size.
What to look for when you buy
35 lb queen or king bed-size weighted blanket
Best for: Larger adults who want a blanket that covers the whole bed
Bed-size options such as Gravity's 35 lb, 90 by 90 inch blanket reach the top of the market's weight range while spreading it across the mattress.
Watch out: Very hard to wash at home and heavy to move; check you can lift it off easily.
See options on Amazon25 to 30 lb single-person blanket
Best for: Larger adults who want concentrated pressure on the body
A blanket sized to one person puts more of its weight on you than a bed-size one, and fits the upper rows of the Sleep Foundation chart.
Watch out: Not for sharing; and too much weight can restrict breathing for some people.
See options on AmazonWeighted blanket with removable cover
Best for: Anyone buying 20 lbs or more
Heavier blankets are hard to wash whole, and the Sleep Foundation notes a washable cover helps a blanket last.
Watch out: Ties or loops must hold the insert in place.

- What is the heaviest weighted blanket you can buy?
- Most top out at 30 lbs, per the Sleep Foundation, and some bed-size models go to 35 lbs, such as Gravity's 90 by 90 inch option.
- Can a weighted blanket be too heavy?
- Yes. The Sleep Foundation warns a blanket that is too heavy can restrict airflow, especially for people with breathing conditions.
- Is a 30 lb weighted blanket too heavy?
- For most people, yes. In the Sleep Foundation chart, 30 lbs appears only as the top of the range for people weighing 125 to 300 lbs, which matches about 10% of 300 lbs.
- Is heavier better for anxiety?
- Not necessarily. Research has used weights around 6 to 8 kg, and comfort and the ability to remove the blanket matter more than maximum weight.
