How we chose: We shortlisted popular, well-reviewed weighted blankets in UK sizes on Amazon.co.uk, compared weights, sizes, fabrics and care instructions from the manufacturer listings, and looked for recurring themes in Amazon.co.uk owner feedback. We based our weight and children's safety advice on manufacturer guidance, NHS trust guidance and the Royal College of Occupational Therapists. We have not personally tested these products; this is a research-based roundup. Our research process.
Weighted blankets are filled with tiny glass beads sewn into small quilted pockets, so the weight spreads evenly over your body. Many people find the gentle, even pressure calming, and they're popular with people who feel restless or anxious at bedtime. Evidence on sleep benefits is still limited, so think of one as a comfort item rather than a treatment, and speak to your GP if you have a sleep problem.
The two decisions that matter most are weight and size. Most makers recommend a blanket of about 10% of your body weight, and a weighted blanket is designed to cover you, not the whole bed. So a 150 × 200cm blanket is right for one adult in a double or king bed, even though it looks small next to a duvet. We explain both below, along with care, warmth and safety for children.
Who this guide is for: Adults who like a heavier, cosier feel in bed or on the sofa, people who sleep hot and want a cooler weighted blanket, and parents looking for a light blanket for an older child. It isn't for babies or toddlers, for anyone who couldn't push it off on their own, or as a substitute for medical advice about sleep or anxiety.

Brentfords is a UK homeware brand, and its weighted blankets have tens of thousands of reviews across the range on Amazon UK. This one is 150 × 200cm and 8kg, with a quilted polyester cover and certified non-toxic glass beads in evenly stitched square pockets. Brentfords recommends a blanket between 7% and 12% of your body weight, so 8kg suits most adults between about 70kg and 110kg. The same blanket comes in other weights, sizes and colours on the listing. It's sold by OnlineHomeShop.
Owners describe it as a warm hug that keeps them cosy without overheating, and one says it helps with restless legs. Feedback on size is mixed: some say it covers a double well, others that it barely does, which is normal because weighted blankets are meant to cover one person. A few owners found the weight slightly uneven. It's a good first weighted blanket if you're not sure you'll get on with one.
What owners and reviewers like
- Excellent value for a weighted blanket
- Huge review base across the range
- Lots of weights and colours
- Even square pockets
Watch-outs
- Polyester cover can feel warm for hot sleepers
- Some reports of uneven weight
- Third-party seller

Silentnight Wellbeing Collection Weighted Blanket, 9kg, supersoft grey
Best for: Heavier adults, or anyone who wants a well-known UK brand
- Weight
- 9kg (6.8kg on separate listings)
- Size
- 150 × 200cm
- Fabric
- Supersoft microfibre, glass bead fill
- Best for
- Adults around 90kg, brand buyers
Silentnight is one of the biggest bedding brands in the UK, and its Wellbeing Collection weighted blanket is 150 × 200cm and comes in 6.8kg or 9kg. Silentnight says the weight should be about 10% of the user's body weight, so this 9kg version suits adults of around 90kg. The glass beads sit in diamond-shaped stitched pockets, which Silentnight says stops them moving and rattling. The cover is a soft microfibre. It's sold by Branded_Bedding, a third-party seller. If you're lighter, the 6.8kg version is on a separate listing, in natural plush or olive and oyster.
Owners say it helps them relax and sleep better, and many say it's well worth the money. It's warm, which some love on cold nights and others find too much in summer. Some find 9kg hard to move about under, so if you're between weights, go lighter.
What owners and reviewers like
- Trusted UK bedding brand
- Diamond pockets keep the beads in place
- Soft, cosy microfibre
- 6.8kg version available
Watch-outs
- Warm in summer
- 9kg is heavy to shift in the night
- Costs more than budget brands

Silentnight Restore Cooling Weighted Blanket, 6.8kg
Best for: People who overheat at night, including during the menopause
- Weight
- 6.8kg
- Size
- 150 × 200cm
- Fabric
- Polyester, one cooling side
- Best for
- Hot sleepers, night sweats
Most weighted blankets are warm because of the dense fill. Silentnight's Restore Cooling version has one side made from a cooling fabric, which Silentnight says helps combat overheating, including from the menopause. It's 150 × 200cm and 6.8kg, with glass beads in stitched pockets, and Silentnight gives a 12-month guarantee. At 6.8kg it suits adults of roughly 60–75kg. It's sold by Amazon.
Owners like the material quality, and one says it helps with night sweats. The cooling effect gets mixed feedback: some find it noticeably cooler, others not very. Some say it slips off the bed, and some found washing difficult because of the weight. It has far fewer reviews than the other blankets here, so treat it as a promising option rather than a sure thing.
What owners and reviewers like
- Cooling fabric on one side
- Silentnight brand and 12-month guarantee
- Sensible 6.8kg weight
- Sold by Amazon
Watch-outs
- Cooling effect is modest for some
- Can slip off the bed
- Fewer reviews so far

Brentfords Teddy Fleece Weighted Blanket, 6kg, 125 × 180cm, charcoal grey
Best for: Snuggling on the sofa in winter, or a single bed
- Weight
- 6kg
- Size
- 125 × 180cm (sold as single)
- Fabric
- Teddy fleece, glass bead fill
- Best for
- Sofa, single beds, winter
If you want a weighted blanket that also works as a cosy sofa throw, Brentfords' teddy fleece version is very soft and warm. This one is 125 × 180cm and 6kg, which suits adults of roughly 55–75kg on a single bed, or curled up on a sofa. Like the standard Brentfords blanket, it has quilted square pockets and glass bead fill, and it comes in other colours and weights, including a 10kg king size on a separate listing. It's sold by OnlineHomeShop.
Owners love the softness and describe it as feeling hugged. They say the weight is well spread and it's good value. Teddy fleece is warm, so it's more of a winter blanket, and it can pick up pet hair. If you sleep hot, choose the cooling Silentnight instead.
What owners and reviewers like
- Very soft and warm
- Good size for a sofa or single bed
- Good value
- Other weights available
Watch-outs
- Too warm for some in summer
- Fleece attracts pet hair
- Smaller than a double-size blanket

Sivio Weighted Blanket, 7kg, 150 × 200cm, grey
Best for: Adults who want soft fleece on both sides
- Weight
- 7kg
- Size
- 150 × 200cm
- Fabric
- Flannel fleece and sherpa, glass bead fill
- Best for
- Adults around 70kg, cold bedrooms
Sivio's blanket is soft flannel fleece on one side and sherpa fleece on the other, in a matching colour, so it feels cosy whichever way up it lands. It's 150 × 200cm and 7kg, suitable for adults of around 60–80kg, and Sivio says its stitching locks the beads into each compartment to stop leaks and noise. Sivio says it's machine washable, but at 7kg you may need a large-drum machine or a launderette. It's sold by Sivio.
Owners say the weight is evenly spread, it feels like a hug and it's very warm through winter. It costs more than Brentfords, and the fleece makes it a cold-weather blanket rather than a year-round one.
What owners and reviewers like
- Soft fleece on both sides
- Even weight distribution
- Good size for one adult
Watch-outs
- Warm; not for hot sleepers
- Heavy to wash at home
- Pricier than budget rivals

Silentnight Kids Weighted Blanket, Wellbeing Collection, 3kg, Spot & Stripe
Best for: Older children of around 30kg, used with an adult's supervision
- Weight
- 3kg
- Size
- 100 × 150cm
- Fabric
- Plush microfibre, bead fill
- Best for
- Children of about 30kg, quiet time
Silentnight's children's weighted blanket is 100 × 150cm and 3kg, with a spot-and-stripe plush cover. Silentnight says it should be about 10% of the child's body weight, so 3kg is designed for a child of roughly 30kg (often around 9–10 years old, but weigh your child rather than going by age). It's hypoallergenic and has a 12-month guarantee. It's sold by Branded_Bedding.
Owners say it's well made, the weight is even and it helps with calm and sleep. Several reported tiny beads leaking from the seams, so check it regularly and stop using it if you see any. Please read our safety section before buying a weighted blanket for a child. NHS trust guidance says children must be able to remove it on their own, it should never cover their head, and it should be removed if they fall asleep.
What owners and reviewers like
- Child-sized and child-weight
- Silentnight brand and 12-month guarantee
- Bright, child-friendly cover
Watch-outs
- Some reports of beads leaking
- Needs adult supervision
- Fewer reviews than adult blankets

Dreamscene Star Weighted Blanket, 3kg, 100 × 150cm, silver grey
Best for: Lighter adults, teens and lap use on the sofa
- Weight
- 3kg
- Size
- 100 × 150cm
- Fabric
- Microfibre star face, teddy fleece reverse
- Best for
- Lap blanket, lighter users
Not everyone wants 7kg or more. Dreamscene's 3kg blanket is a gentler introduction to weighted blankets and works well as a lap blanket on the sofa or at a desk. It's 100 × 150cm, with a textured star microfibre side and a teddy fleece reverse, and the beads sit in evenly stitched pockets of about 5 inches. Dreamscene says it's only suitable for ages 3 and up, and recommends a blanket of 7–12% of body weight. It comes with a carry case and is sold by OnlineHomeShop.
Owners praise the quality, the soft fleece side and the value for money. Some bought it for children who struggle to sleep. If you do, follow the children's safety advice below. At 3kg it will feel light for most adults in bed, so it's best for lap use or for smaller adults.
What owners and reviewers like
- Light and easy to manage
- Soft two-sided finish
- Great value
- Carry case included
Watch-outs
- Too light for most adults in bed
- Small size
- Warm fleece reverse

What weight should you choose?
Most manufacturers recommend a weighted blanket that's about 10% of your body weight. Some, like Brentfords and Dreamscene, give a range of 7–12%. If you're between sizes, or you've never used one, go lighter: a blanket that's too heavy is harder to move under and more likely to end up on the floor.
| Your body weight | About 10% | Blanket to look for |
|---|---|---|
| 30kg (4st 10lb) | 3kg | 3kg child or lap blanket |
| 50kg (7st 12lb) | 5kg | 4–6kg |
| 60kg (9st 6lb) | 6kg | 6kg |
| 70kg (11st) | 7kg | 6.8–7kg |
| 80kg (12st 8lb) | 8kg | 8kg |
| 90kg (14st 2lb) | 9kg | 9kg |
| 100kg+ (15st 10lb+) | 10kg+ | 10kg (or 9kg if you prefer lighter) |
Sharing a bed? Each person should have their own blanket at their own weight. A single heavy blanket over two people won't feel right for either of you.
What size do you need?
Weighted blankets are sized to cover one person from shoulders to feet, not to hang over the sides of the bed like a duvet. That's intentional: overhanging weight pulls the blanket off the bed. As a rough UK guide:
- 100 × 150cm: children, lap use or smaller adults on a single bed.
- 125 × 180cm: one adult on a single bed or the sofa.
- 150 × 200cm: one adult on a double, king or super king bed. This is the most popular adult size.
Use it on top of a thin sheet or under your normal duvet in winter. In summer, many people use it on its own.
Fabric, warmth and washing
The beads trap heat, so weighted blankets are warmer than they look. Teddy fleece and sherpa are the cosiest and best for cold bedrooms and sofas. Microfibre and polyester are mid-weight. Cooling fabrics, like Silentnight's Restore, suit hot sleepers. If you already sleep hot, avoid fleece. If your bedroom is cold, a weighted blanket pairs well with an electric underblanket to warm the bed first. Never use a weighted blanket on top of a heated throw or electric overblanket that's switched on.
Check the care label before you buy. Many weighted blankets are machine washable, but a 7–9kg wet blanket is very heavy and may be too much for a standard home washing machine, so a launderette may be easier. A removable, washable cover makes life much simpler. Dry it flat or on a large airer rather than hanging it by one edge, which can stretch the stitching. For more ways to keep warm in winter, see our heated throws guide.
Weighted blankets for kids: safety first
Weighted blankets are popular for children, particularly neurodivergent children, but they carry real risks if used wrongly. NHS trust and Royal College of Occupational Therapists guidance includes these points:
- Never use one with a baby. The Lullaby Trust says weighted blankets aren't recommended for babies under one year because of the risk of overheating and head covering. Many manufacturers say 3+ only.
- Around 10% of the child's body weight, and follow the maker's guidance.
- The child must be able to remove it on their own, easily, and move their arms and legs under it.
- Never cover the head, face or neck, and never roll or wrap a child in one.
- Don't let it hang over the side of the bed.
- Supervise use and take breaks. Sheffield Children's NHS Foundation Trust suggests sessions of up to 20 minutes and says to gently remove it if a child falls asleep.
- Watch for overheating, breathing difficulty or distress, and stop straight away if you see them.
- Never use it as a restraint.
If your child has a health condition that affects breathing, temperature control or movement, talk to their GP or occupational therapist first.
Is a weighted blanket the right buy?
- Choose a weighted blanket if you like heavy bedding, find firm pressure soothing, or tend to kick off a light duvet.
- Choose a mattress topper instead if your real problem is an uncomfortable bed. Our mattress topper guide covers memory foam, fibre and cooling toppers.
- Choose an electric blanket or heated throw if you mainly feel cold. They warm you for pennies an hour at the October 2026 price cap.
Buying one as a present? A 6–7kg blanket in a neutral colour is the safest bet for an adult you don't know the weight of. For other ideas, see our stocking fillers for adults.
FAQs
What weight weighted blanket should I get?
About 10% of your body weight is the usual guidance. Some makers say 7–12%. If you're between weights or new to weighted blankets, choose the lighter option.
What's the best weighted blanket for kids?
A child-sized blanket of around 10% of the child's body weight, such as Silentnight's 3kg kids' blanket for a child of about 30kg. Only use one with supervision, never with a baby, and make sure the child can remove it easily. Remove it if they fall asleep.
Can you sleep with a weighted blanket all night?
Many adults do, but take it off if you feel too hot or restricted. NHS trust guidance for children says to remove it once a child is asleep.
What size weighted blanket for a double bed?
150 × 200cm for one adult. Weighted blankets are designed to cover your body, not the whole mattress, so each person sharing a bed should have their own.
Are weighted blankets hot?
They can be, because the dense fill traps heat. Fleece versions are warmest. Look for a cooling fabric, such as Silentnight's Restore, if you sleep hot.
Can you wash a weighted blanket?
Many are machine washable, but check the label. A 7–9kg blanket is very heavy when wet, so you may need a large-drum machine or a launderette. A removable cover makes cleaning much easier.
Where can I buy a weighted blanket in the UK?
Amazon.co.uk stocks a wide range, including Silentnight, Brentfords, Sivio and Dreamscene, alongside high-street bedding retailers. Check the weight, size and seller before you buy, and the returns policy, since opened bedding can't always be returned.
Do you get commission?
Yes. If you buy through our links, Amazon may pay us a small commission at no extra cost to you. It doesn't affect which products we include. See our Affiliate Disclosure.
