Ultimate Weighted Blanket UK Guide 2023 + Offers and Top 5

Welcome to our definitive weighted blanket UK guide, featuring the five weighted blankets we think are worth your money.

The idea of a weighted blanket (according to the manufacturers) is that it has a ‘relaxing effect on joints, muscles and tendons’. This helps you ‘feel rested physically and psychologically’. That’s according to Gravity Blankets.

Things to keep in mind when shopping for a weighted blanket: 

  • Heavier people need heavier weighted blankets. Manufacturers such as Gravity Blankets suggest that you should get one which is about 10% of your bodyweight. Other guides suggest about 7-12% of your bodyweight.
  • Some have machine washable covers which can be removed. Others are a bit fussier and have to be ‘spot cleaned’ which is a bit like when your mum used to spit on a hanky and wipe your face as you stood at the school gate. 
  • Some are made from breathable natural materials like cotton, whilst others are made from synthetic materials. Cotton tends to be a more expensive option.
  • Weighted blankets vary in size quite a lot, although most of them are somewhere around a single size duvet. You can use a weighted blanket without an extra cover, but if you plan to use your own duvet cover on top then don’t assume it will fit every weighted blanket on the UK market. 
  • ​There are various safety guidelines with weighted blankets. They vary with each product, but common guidelines are that they shouldn’t be used by pregnant women, people with circulatory issues or young children. I encourage you to read the safety advice before you buy one. 

With all that out the way, here are five of the best weighted blankets you can buy in the UK. We looked at things like value for money, customer review scores and product specification before making our choices. We’ve tried to pick a good range, including some cheap weighted blankets for those who are just curious, right through to the more expensive and luxurious weighted blankets.

Prices are correct at the time of typing in 2023.


1. John Lewis & Partners Specialist Synthetic Weighted Blanket – 2.5kg to 11.5kg – £80-£110

John Lewis & Partners sell a couple of weighted blankets for adults under their own name, as well as some other brands. They are slightly wider than a standard single duvet. 

Natural or synthetic?

Although they’re both described as ‘synthetic’ because of some of the inner fillings, one of them has a cotton cover whilst the other has a manmade cover which is fleecier and softer. I would go for the cotton one if you like to feel cool in bed. Choose the fleecier one if you want to feel warmer.

The cotton weighted blanket from John Lewis & Partners is 200 thread count, which means that it will feel crisp and fresh (higher thread counts feel soft and silky). 

We’ve picked out the weighed blanket with the cotton cover for our top 5, as it’s available in many more different weights and it has very good reviews (4.5/5 at the time of writing).

You can pick from a good range of weights, starting at 4.5kg which is recommended for about 6-9 stone right up to 11.5kg which is recommended for about 16 stone+. There are some safety warnings which come with these blankets, so have a read of those before you buy one. For example, John Lewis & Partners don’t recommend using one if you’re pregnant or under three years old.

Limited colours

On the downside, John Lewis & Partners don’t offer the fancy range of colours and styles, and the free returns option that you get with Gravity Blankets (see #3). They’re not a very common bedding size (150cm x 200cm) so you’d struggle to find a duvet cover for it.

Also, the cotton weighted blanket can’t go in the washing machine and you can’t tumble dry it. The recommendation is that you ‘spot clean only and air on a dry day’.

Pros: choice of cotton or fleecy versions, respected brand with awards for customer service

Cons: poor choice of colours, not standard bedding sizes, relatively expensive, cotton version not machine washable

2. Brentfords Weighted Blanket – 4kg, 6kg or 8kg – £17-£26

If you want to try out a weighted blanket but don’t want to spend a huge amount of money then this cheap Brentfords weighted blanket is worth considering. We’ve included it because it offers a lot for the money and scores a very impressive 4.6/5 from more than 16000 reviews on Amazon.

It comes in three weights – 4kg, 6kg and 8kg. If we apply the usual rule that you should aim for 10% of your bodyweight then that would make them suitable for people who weigh about 6 stone, 9 stone and 12 stone (or pick the closest one, obviously).

The size won’t be right for everyone

The main downsides that I can spot are that it comes in unusual sizes. The lightest one is quite small at 125cm x 150cm which is 40-50cm shorter than a standard duvet cover. Having said that, the heavier ones are bigger so there is some logic to it.

The description recommends that you can attach your own cover, although none of the sizes are standard duvet cover sizes so you’ll need to improvise a bit. As far as I can tell, you can’t machine wash it. 

As you might expect for this price, it doesn’t use particularly fancy materials and is 100% synthetic. However, synthetic materials tend to be better for people with allergies as they don’t gather dust so easily.

You can pick from a choice of silver or pink.

Pros: very low price, positive reviews, choice of weights

Cons: unknown brand, modest choice of colours, not a standard size

3. Gravity Blanket – 4kg to 12kg – £169

Gravity Blankets are probably the most famous name in the UK for weighted blankets. They’ve been going since 2013 and they get a decent score of 3.6/5 on TrustPilot from 2000+ customers or 4.4/5 on Amazon.

They’re also one of the more expensive weighted blanket companies – so what are you getting for your money?

Easier returns than most

Firstly, they come with a ‘guarantee that your mood and the quality of your sleep will improve’ within 28 days. You have to pay returns postage, but it’s still a good option if it’s not right for you. 

They also come in a much wider range of colours, weights and styles than most other weighted blankets. When we checked, there were five different weight options – ranging from 4kg for someone who weighs about 5-8 stone through to 12kg for someone who weighs more than 17 stone (there’s more detailed guidance here). They also offer a choice of a warmer velvety version or one which is double sided so that’s it’s fleecy on one side for winter and cotton on the other side for summer.

The idea is that you don’t share the blanket, so the standard size is the same as a single duvet whilst the larger one is narrower than a double duvet but a bit longer so it is more suited for a taller or wider than average person. 

Better materials than most rival weighted blankets

Other things which bump up the price are the fact that it uses organic cotton (as well as some manmade materials). Cotton is naturally breathable, so it’s a good material for blankets.

Gravity Blankets seem to charge the same price for their blanket regardless of which weight you choose, whereas some companies charge more for their heavier blankets. So, they’re particularly good value if you’re heavier than average.

It’s also machine washable, which is a real plus point in my opinion (have a read of the instructions and check your washing machine can handle the weight).

Pros: big name brand in the weighted blankets market, returns option, machine washable, organic cotton

Cons: much more expensive than most weighted blankets

4. Silentnight Weighted Blanket – 3kg to 9kg – £55-£72

If you’d like to get a mid-priced weighted blanket from a brand you know then this one from Silentnight is worth a look. 

Silentnight is the UK’s biggest mattress company and they make pretty much everything in the bedding and beds market. Overall, the brand scores an average of 4.2/5 on TrustPilot. This weighted blanket scored 4.6/5 on Amazon when we checked.

It comes in three weights. The Silentnight ‘kids’ weighted blanket weighs 3kg and ‘should be approximately 10% of the child’s body weight’ according to the description (a quick Google suggests that the average 10 year old weighs 32kg – please do read the safety instructions and guidance though).

The other weights available are 6.8kg and 9kg. Silentnight recommend that you should only use them if you’re over 18. If we apply the 10% rule, then that would make the 6.8kg version ideal for someone who weighs 11 stone. The 9kg version is best for someone who weighs 14 stone.

It’s made from ‘soft quilted microfibre’ which is a posh way of saying that it is synthetic rather than a natural material such as cotton.

​Rather appealingly, it is machine washable. The majority of washing machines can cope with 7kg or more but there are a few out there which have a lower weight limit. 

Pros: famous bedding brand with good reputation, machine washable, range of weights available

Cons: lack of colour options, synthetic materials are not as breathable as cotton

5. Simba Orbit Weighted Blanket – 6.8kg or 9kg – £169

Simba is a popular name in the mattress market but they also sell a weighted blanket called the ‘Simba Orbit’. It’s worth considering as the Simba brand scores an outstanding 4.4/5 from thousands of reviews on TrustPilot.

The blanket only comes in two weights, one of which is designed for people who weigh about 9 – 13 stone and the other for people who weigh more than 13st 7lb stone. The official blurb says that you should ‘Choose the weight of blanket that’s closest’ and that ‘if you weigh exactly half-way between those numbers, choose the lighter option’.

Unlike the Simba mattress, you don’t get a trial period but it’s still got a lot going for it.

It has a cotton cover whereas a lot of cheaper weighted blankets have a synthetic cover which is usually less breathable. Another plus point, in my opinion, is that it’s the same size as a standard single duvet. A lot of weighted blankets are rather peculiar sizes so it wouldn’t be easy to use your own duvet cover if you decided you wanted to.

The outside cover is machine washable (on a cold setting) but you can’t wash the inner part of the blanket in a machine.

As with all these weighted blankets, there are warnings about not using the blanket if you have certain conditions so do have a proper read before you buy it.

Pros: standard single duvet size, breathable cotton cover, partially machine washable

Cons: more expensive than many weighted blankets, only two weights, no trial period (unlike most Simba Sleep products)
