# Best 4.5 Tog Duvet 2026: 10 Ranked, and Why 'Heavyweight' Means 4.5 Tog Source: https://www.ranked10.co.uk/home/best-4-5-tog-duvets Published: 2026-09-18 | Updated: 2026-09-19 | Prices checked on Amazon UK on 2026-09-18 Every duvet on this list is sold as a 4.5 tog duvet, yet the listings cannot agree on what that number means. The DN Collection single files its 4.5 tog duvet under 'Heavyweight'. The Good Nite king files the same rating under 'Medium'. Linens Limited's Bedtime Bliss files it under '4.5 Tog'. Good Nite goes further: one bullet claims 1.37 kg of filling, while the same listing puts the whole item at 1.4 kg. That leaves 30 g for the cover, the stitching and the packaging. Tog measures warmth, not weight, and none of these ten sheets will tell you how much filling you actually get. We ranked ten of the best 4.5 tog duvet options on Amazon by weighing four things: how many ratings each one has, the average score those ratings produce, the price you pay for the size, and how much the listing actually tells you about filling, size and care. Where a listing contradicts itself, we say so. ## The ranking ### 1. Silentnight Anti Allergy Double 4.5 Tog Duvet - Price: £16.99 | Amazon rating: 4.6 from 25,304 ratings - Full review: https://www.ranked10.co.uk/home/best-4-5-tog-duvets/silentnight-anti-allergy-double-duvet - Buy on Amazon: https://www.amazon.co.uk/dp/B01ISWOP4I?tag=ranked10-21 The largest sample in the list — 25,304 ratings averaging 4.6, with 77% of them five-star, at £16.99 for a double. This tops the ranking on volume, not on a slogan. 25,304 ratings average 4.6, and 77% of them are five-star, with just 1% at one star. At £16.99 for a double it also undercuts most of the field, including the Siebenschläfer double at £23.95 and the Silentnight Summer Breeze at £24.99. That combination of sample size and price is why this 4.5 tog duvet leads. The engineering here is about fibres rather than filling weight. Silentnight says its anti-allergy fibres are approved by the British Allergy Foundation and that the filling is effective against 99.9% of bacteria; the cover is microfibre and the whole thing is machine washable. Crucially, it carries a 5-year manufacturer's guarantee and is made in the UK — the longest guarantee here, against the 2-year cover on both Slumberdown models. That said, the spec table is a mess. It lists 'Camping' both as the recommended use and as the sport type, for a double bed duvet. It gives no filling weight and no dimensions of its own. Worth noting too: the warmth field says only 'Lightweight', which tells you less than the tog rating does. If you need a winter duvet or a king size, look elsewhere. Pros: 25,304 ratings averaging 4.6, with 77% five-star and 1% one-star; £16.99 for a double, below both Slumberdown options here; Allergy UK-approved anti-allergy fibres, effective against 99.9% of bacteria according to the listing; 5-year manufacturer's guarantee — the longest in this list; Machine washable with a soft microfibre cover Cons: Spec table files it under 'Camping' for both use and sport type; No fill weight anywhere in the listing; No dimensions in the specs beyond 'Double Bed'; Warmth described only as 'Lightweight' — nothing in grams ### 2. Siebenschläfer Light Summer Duvet 4.5 Tog, Double - Price: £23.95 | Amazon rating: 4.8 from 19,531 ratings - Full review: https://www.ranked10.co.uk/home/best-4-5-tog-duvets/siebenschlafer-light-summer-duvet - Buy on Amazon: https://www.amazon.co.uk/dp/B0BSV7YD6Z?tag=ranked10-21 The best average score in the list — 4.8 from 19,531 ratings, 86% five-star — and the only one claiming a 95°C wash. A 4.8 average from 19,531 ratings is the highest score here, and 86% of those ratings are five-star — ten points clear of the Slumberdown Summer Nights at 76%. It ranks 13th in Amazon's Duvets category. At £23.95 for a double it is about £7 more than the Silentnight Anti Allergy, so you are paying for the score and the OEKO-TEX testing, not for a bigger fill. The practical selling point is the wash. The listing says the summer duvet 4.5 tog is washable at 95°C, far above the 40°C most of these listings specify, and high temperatures are the usual way to deal with dust mites and sweat. In theory that is a real hygiene advantage for allergy sufferers. Meanwhile the filling is microfibre and the duvet is OEKO-TEX tested for harmful substances. The catch is the spec table. The fabric type field contains an email address, 'Gpsr@dejo-commerce.com', which tells you nothing about the fabric. The brand is spelled 'Siebenschläfer' in the title and 'Siebschläfer' in a bullet. There is no fill weight and no fill quantity anywhere, and the country of origin is Estonia. If a precise fibre breakdown matters to you, this listing will not give you one. Pros: 4.8 average from 19,531 ratings — the highest here; 86% of ratings are five-star; Washable at 95°C, against 40°C on most of this list; OEKO-TEX tested for harmful substances; Ranks 13th in Amazon's Duvets category Cons: No filling weight or fill quantity stated; Fabric type field shows an email address, not a fabric; Brand name is misspelled in one bullet; £23.95 is about £7 more than the Silentnight Anti Allergy double ### 3. Slumberdown Summer Nights 4.5 Tog Double Duvet - Price: £17.99 | Amazon rating: 4.6 from 9,737 ratings - Full review: https://www.ranked10.co.uk/home/best-4-5-tog-duvets/slumberdown-summer-nights-duvet - Buy on Amazon: https://www.amazon.co.uk/dp/B0GYS4DMKL?tag=ranked10-21 One of the few listings that states its size and depth: 200 x 200 cm and 2 cm thick, for £17.99. 9,737 ratings average 4.6, with 76% five-star and 2% one-star. It sits £1 above the Silentnight Anti Allergy double and £5.96 below the Siebenschläfer. However, what separates it is disclosure: Slumberdown states the size as 200 x 200 cm and the thickness as 2 cm, two numbers most listings here leave out entirely. The listing calls it a 4.5 tog duvet double, filled with non-allergenic hollowfibre and moisture-wicking fibres meant to move air rather than trap it. It is machine washable at 40°C and tumble dryer friendly, made in the UK, and covered by a 2-year quality guarantee. In practice that is a straightforward summer quilt: thin, washable and sized for a standard double bed. Even so, the disclosure stops short of the filling. There is no weight in grams, so the 2 cm thickness is the only build figure you get. The listing also carries a 'Packaging may vary' line, which is boilerplate rather than a product detail. If you have a king or single bed, this exact listing is not for you. Pros: 9,737 ratings averaging 4.6, 76% five-star; States its size (200 x 200 cm) and its thickness (2 cm); Machine washable at 40°C and tumble dryer friendly; Made in the UK with a 2-year quality guarantee; £17.99 for a double Cons: No filling weight given; Double size only in this listing; 'Packaging may vary' line adds nothing; 2 cm thickness is the only build measurement offered ### 4. Silentnight Summer Breeze Lightweight Duvet 4.5 Tog - Price: £24.99 | Amazon rating: 4.6 from 12,201 ratings - Full review: https://www.ranked10.co.uk/home/best-4-5-tog-duvets/silentnight-summer-breeze-4-5-tog - Buy on Amazon: https://www.amazon.co.uk/dp/B00TQWMVV4?tag=ranked10-21 The most expensive item in the ranking at £24.99 — £8 above the brand's own Anti Allergy double, with no fill weight to explain the gap. 12,201 ratings average 4.6, with 76% five-star and 1% one-star, so the score is solid. The price is the problem: at £24.99 it is the most expensive item in this ranking, £8 above Silentnight's own Anti Allergy double at £16.99 and £1.04 above the Siebenschläfer. The listing gives no filling weight to explain that. The design brief is breathability. Silentnight describes moisture-wicking covers and lightweight fibres that let heat and humidity escape, aimed at over-heaters. It is hypoallergenic and machine washable. By contrast with the Anti Allergy model, the listing states no Allergy UK approval and no guarantee length at all. Worth noting what the spec table does with the tog rating: it puts '4.5 Tog' in the pattern field, the colour field and the style name, and lists sport type as 'No'. There are no dimensions and no fill weight. If you want a lightweight summer duvet with a stated size, the Slumberdown Summer Nights is £7 cheaper and gives you 200 x 200 cm; if you want the Silentnight name, the Anti Allergy double is cheaper still. Pros: 12,201 ratings averaging 4.6, 76% five-star; Moisture-wicking cover and breathable fibres aimed at hot sleepers; Hypoallergenic and machine washable; Same brand as the top-ranked duvet here Cons: £24.99 — the highest price in this list; No filling weight and no dimensions; No Allergy UK approval or guarantee length stated, unlike the brand's Anti Allergy model; Spec table repeats '4.5 Tog' as colour, pattern and style ### 5. Slumberdown Climate Control King Size 4.5 Tog Duvet - Price: £18.95 | Amazon rating: 4.6 from 4,309 ratings - Full review: https://www.ranked10.co.uk/home/best-4-5-tog-duvets/slumberdown-climate-control-king-duvet - Buy on Amazon: https://www.amazon.co.uk/dp/B06XG6ZC1W?tag=ranked10-21 The cheapest king here at £18.95 — £5.64 below the Good Nite king — with 4,309 ratings averaging 4.6. 4,309 ratings average 4.6, with 74% five-star and 2% one-star. As a 4.5 tog king size duvet at 225 x 220 cm it is £5.64 cheaper than the Good Nite king at £24.59 and £5.20 cheaper than the Linens Limited Bedtime Bliss king at £24.15. That is the main reason it sits above both. Slumberdown's pitch is temperature regulation: 'breathable temperate fibres' meant to stop overheating. It is non-allergenic hollowfibre, machine washable at 40°C, tumble dryer friendly, made in the UK and covered for 2 years. At the same time, the 225 x 220 cm measurement is the only size figure in the listing — no thickness, no fill weight. That said, 'Climate Control' is doing marketing work the specs do not back up. There is no stated cooling technology beyond the fibre description, and no filling weight to set against the Good Nite's 1.37 kg claim. You are buying a well-reviewed, well-priced king with a normal hollowfibre fill. Pros: King size at 225 x 220 cm for £18.95; £5.64 cheaper than the Good Nite king; 4,309 ratings averaging 4.6; Made in the UK, machine washable at 40°C, 2-year guarantee; Non-allergenic hollowfibre filling Cons: No filling weight, so it cannot be compared with the Good Nite's 1.37 kg claim; No thickness given; 'Climate Control' is a name, not a measured figure in the specs; 2% of ratings are one-star ### 6. Linens Limited Easy Care Duvet 4.5 Tog, Double - Price: £16.21 | Amazon rating: 4.3 from 3,677 ratings - Full review: https://www.ranked10.co.uk/home/best-4-5-tog-duvets/linens-limited-easy-care-duvet - Buy on Amazon: https://www.amazon.co.uk/dp/B00A39MFRE?tag=ranked10-21 The cheapest item in the ranking at £16.21, but also the lowest average score: 4.3 from 3,677 ratings. At £16.21 this is the cheapest item in the ranking — £0.78 below the Silentnight Anti Allergy double and £8.78 below the Silentnight Summer Breeze. The trade-off shows in the ratings: 4.3 from 3,677 reviews, with 65% five-star, the lowest five-star share here, and 8% at two stars or below. The build differs from the microfibre duvets around it. Linens Limited uses a polypropylene cover with a hollowfibre filling, marketed as anti-allergy and aimed at allergy sufferers. It is machine washable at 40°C and also hand washable, and the listing says it is tested to UK, European and global standards. Meanwhile the warmth field is filled in as '4.5 Tog' rather than a description of warmth, so it adds nothing. In short, this is a budget buy and the numbers say so. If price is the deciding factor and 65% five-star is acceptable to you, it does the job as a 4.5 tog quilt double. If you want the highest confidence, the Silentnight Anti Allergy has 25,304 ratings at 4.6 for £0.78 more. Pros: Cheapest item in the ranking at £16.21; 3,677 ratings averaging 4.3; Polypropylene cover with hollowfibre filling, marketed as anti-allergy; Machine washable at 40°C and hand washable; Double size at 200 x 200 cm Cons: 65% five-star — the lowest five-star share in this list; 8% of ratings are two-star or below; Warmth field merely repeats '4.5 Tog'; No fill weight given ### 7. DN Collection Single Duvet 4.5 Tog Box Stitched - Price: £17.99 | Amazon rating: 4.4 from 6,853 ratings - Full review: https://www.ranked10.co.uk/home/best-4-5-tog-duvets/dn-collection-45-tog-duvet - Buy on Amazon: https://www.amazon.co.uk/dp/B0979CMXF3?tag=ranked10-21 A single 4.5 tog duvet at 135 x 200 cm for £17.99 — and the listing that files its 4.5 tog rating under 'Heavyweight'. 6,853 ratings average 4.4, with 71% five-star and 5% one-star. It is a single 4.5 tog duvet measuring 135 x 200 cm, at £17.99 — the same price as the Slumberdown Summer Nights double, which is worth noting if you buy by size rather than by tog. The construction is box-stitched with corner piping on four sides, which the listing says keeps the hollowfibre filling evenly distributed instead of drifting to the bottom. The cover is soft-touch microfibre, it is hypoallergenic and machine washable at 40°C, and the range comes in 1.5, 2.5 and 4.5 tog. As a result it is the most flexible size range here — single, double, king and super king. However, this is the listing that proves the point about tog ratings. The same product is a cool summer quilt 4.5 tog on one line and 'Heavyweight' in the fabric warmth description on another. It also lists 'Single' in the pattern field. The catch for buyers: no fill weight and no tog explanation, so you are trusting the number rather than a measurement. Pros: 6,853 ratings averaging 4.4, 71% five-star; Available in single, double, king and super king; Box-stitched with 4-side corner piping to hold the filling; Offered in 1.5, 2.5 and 4.5 tog; Hypoallergenic microfibre cover, machine washable at 40°C Cons: Fabric warmth field says 'Heavyweight' despite the 4.5 tog rating; £17.99 for a single — the same price as a double from Slumberdown; No fill weight given; 5% of ratings are one-star ### 8. MHG Living Single 4.5 Tog Lightweight Summer Duvet - Price: £18.99 | Amazon rating: 4.4 from 227 ratings - Full review: https://www.ranked10.co.uk/home/best-4-5-tog-duvets/mhg-living-single-summer-duvet - Buy on Amazon: https://www.amazon.co.uk/dp/B09H3FLFV4?tag=ranked10-21 OEKO-TEX certified and made in the UK at £18.99, but the size list in its bullets is unusable: 'Single (14.55x200cm)', 'King (24.50x220cm)'. Only 227 ratings, averaging 4.4, with 71% five-star and 7% one-star — the smallest sample in the top ten and a wider spread than most. At £18.99 it is £1 above the DN Collection single and £2.78 above the Linens Limited Easy Care double. On paper the spec is decent: OEKO-TEX certified hollowfibre filling, a microfibre stripe cover, hypoallergenic, machine washable at 40°C and tumble dryable on low heat, made in the UK. The title lists the single as 135 x 200 cm. Meanwhile the filling resists dust mites and bacteria according to the listing, which is the usual pitch for a summer quilt. The catch is the size bullet. It offers 'Single (14.55x200cm), Double (200x200cm), King (24.50x220cm), or Super King (260x220cm)'. Two of those figures cannot be right — 14.55 cm and 24.50 cm are not bed widths, and the listing's own title says 135 x 200 cm, so a digit has gone missing. Either way, 227 ratings is a thin base to buy on, and 7% are one-star. Pros: OEKO-TEX certified hollowfibre filling; Machine washable at 40°C and tumble dryable on low heat; Microfibre stripe cover, hypoallergenic; Made in the UK; £18.99 for a single at 135 x 200 cm Cons: Size bullet lists 'Single (14.55x200cm)' and 'King (24.50x220cm)' — figures that cannot be right; Only 227 ratings to judge it on; 7% of ratings are one-star; No fill weight stated ### 9. Linens Limited Bedtime Bliss Duvet 4.5 Tog, King - Price: £24.15 | Amazon rating: 4.2 from 261 ratings - Full review: https://www.ranked10.co.uk/home/best-4-5-tog-duvets/linens-limited-bedtime-bliss-king - Buy on Amazon: https://www.amazon.co.uk/dp/B003GNTFS6?tag=ranked10-21 Ninth of ten: 261 ratings at 4.2, with 60% five-star — the lowest five-star share and the highest two-star share here. 261 ratings average 4.2, with 60% five-star, 6% two-star and 3% one-star. That is the weakest rating profile in this ranking, and it sits at £24.15 for a king — £5.20 above the Slumberdown Climate Control king at £18.95, which averages 4.6 from 4,309 ratings. The specification itself is reasonable: ultra-fine siliconised hollowfibre filling, a supersoft polyester/cotton cover, and channel stitching to keep the filling in place. It is machine washable at 40°C and tumble dryable, and made in the UK like the rest of the Linens Limited range. As with the Easy Care, the warmth field is filled in as '4.5 Tog' rather than a description, so the table adds nothing to the rating. Worth noting the pattern: both Linens Limited entries in this list have the two lowest average scores of the ten, 4.3 and 4.2, and the two lowest five-star shares, 65% and 60%. Neither states a fill weight. If you want a king under £20, the Slumberdown Climate Control is cheaper, better rated and states 225 x 220 cm. That said, if you specifically want the siliconised hollowfibre feel, this is the only one here describing it. Pros: Ultra-fine siliconised hollowfibre filling with a polyester/cotton cover; Channel stitching to keep the filling in place; Machine washable at 40°C and tumble dryable; King size, made in the UK Cons: 4.2 average from just 261 ratings; 60% five-star — the lowest in this list; £24.15 is £5.20 more than the Slumberdown Climate Control king; No fill weight and no dimensions in cm stated ### 10. Good Nite King Size Duvet 4.5 Tog, 230 x 220 cm - Price: £24.59 | Amazon rating: 4.4 from 73 ratings - Full review: https://www.ranked10.co.uk/home/best-4-5-tog-duvets/good-nite-4-5-tog-duvet - Buy on Amazon: https://www.amazon.co.uk/dp/B0D983KCW2?tag=ranked10-21 The listing that does not add up: 1.37 kg of filling inside a 1.4 kg item, and 9% one-star ratings from just 73 reviews. 73 ratings average 4.4, but 9% of them are one-star — the highest one-star share in this list. It is also the second most expensive item here, at £24.59 for a 4.5 tog king size duvet measuring 230 x 220 cm, behind only the Silentnight Summer Breeze. The spec sheet is where it gets interesting. Good Nite says the filling weighs 1.37 kg and the whole item weighs 1.4 kg. That leaves 30 g for the microfibre cover, the stitching, the eight lacing pockets and the packaging — on a 230 x 220 cm duvet. Meanwhile the fabric warmth field says 'Medium' for a 4.5 tog summer quilt. In practice you cannot have both numbers right. There are real features too: eight lacing pockets around and on the sides, quilting to stop the filling clumping, and a compressed roll that the listing says needs 48 hours to recover its loft. The catch is the sample. Seventy-three reviews is thin against 25,304 for the Silentnight at the top. If you want a cheaper king with a stated size, the Slumberdown Climate Control is £5.64 less. If you want the lacing pockets, this is the only one here offering them. Pros: 8 lacing pockets around and on the sides; Quilted to stop the filling clumping; Compressed roll delivery with a 48-hour recovery note; 4.4 average with 74% five-star; King size at 230 x 220 cm Cons: Claims 1.37 kg of filling and a 1.4 kg item weight — leaving 30 g for cover, stitching and packaging; Files a 4.5 tog quilt under 'Medium' warmth; Only 73 ratings, 9% of them one-star; £24.59 is the second-highest price in this list ## Verdict For most homes, the Silentnight Anti Allergy Double is the safe pick: 25,304 ratings averaging 4.6, £16.99, Allergy UK-approved fibres and a 5-year guarantee. If you want the highest average score rather than the largest sample, the Siebenschläfer is the best 4.5 tog duvet here at 4.8 from 19,531 ratings, and it is the only one stating a 95°C wash. If you need a king, the Slumberdown Climate Control at £18.95 undercuts the Good Nite king by £5.64 and does not quote a filling weight that its own item weight contradicts. Either way, check the size before you buy: the cheapest 4.5 tog duvet in the list, the Linens Limited Easy Care at £16.21, comes as a double only.
