Best Flannel Sheets: Warm Sets Compared by Weight and Feel
Six queen flannel sheet sets compared by the weight each one prints, in GSM or ounces, plus pocket depth, a drawback for each and queen prices from $59.27.
The bed is cold when you climb in, or the set feels soft for a week and then turns fuzzy. Picking the biggest number on the label doesn’t fix either, because the six queen sets below print their weight in two different units: 140 or 180 GSM on two pages, 5, 5.6 or 6 oz with no area attached on three, and nothing on the sixth, so a bigger-looking number doesn’t tell you which cloth is heavier (our reading). Below is how to read those numbers, then the six sets with their printed weight, queen price and a drawback each, and how to choose between them.
The short answer
| Pick | Weight as printed | Best for | Price (reference) |
|---|---|---|---|
| Mellanni Flannel Cotton Sheet Set, Heavyweight 180GSM | 180 GSM | The highest GSM here, at the lowest price | $59.27 |
| The Company Store Classic Ultra-Cozy Cotton Flannel Bed Sheet Set | 5 oz, no area unit | The lowest-priced of the three ounce-weighted sets | $179 |
| Crane & Canopy Soft White Flannel Sheet Set | 5.6 oz, no area unit | Sleepers without a top sheet: it is sold with or without one | $219 |
| Brooklinen Brushed Flannel Core Sheet Set | 140 GSM | A lighter flannel, pitched at people who run chilly | $229 |
| Coyuchi Cloud Brushed Organic Flannel Sheet Set | 6-ounce, no area unit | GOTS certified organic cotton | $318 |
| Boll & Branch Flannel Sheet Set | No weight number | Organic cotton and an 18-inch pocket | $349 |
Queen prices. Boll & Branch’s $349 is for its solid colours (the patterned versions cost $299 to $399), and The Company Store’s $179 is for four of its colours ($199 for twelve others, and one clearance colour lists under $100).
How to read a flannel label
Three things on a flannel listing shape what you get: the weight and the unit it is printed in, how the cloth is brushed, and what the maker says about the first washes. The lines below are each one maker’s statement about its own cloth, not a rule for flannel.
The weight comes in two units, and one has no area
Brooklinen prints 140 GSM and Mellanni 180 GSM. GSM is grams per square metre, so those two compare directly: the Mellanni is 40 GSM heavier (our arithmetic). Crane & Canopy prints “5.6 oz weight”, The Company Store “5 oz. cotton flannel” and Coyuchi “Weighty 6-ounce flannel”, each with no area attached. Those three can be ranked against each other only if all three mean the same thing, which the pages don’t say (our reading), and none can be turned into GSM from what is printed, so we don’t convert. Boll & Branch prints no weight number; its FAQ calls the fabric “midweight”.
So compare GSM with GSM and ounces with ounces, and between the two groups ask the brand which area its ounces are per (our suggestion).
Brushed, and on how many sides
Mellanni’s 180 GSM page is the one of the six that gives a side count: “Double brushed on both sides”. Brooklinen, Crane & Canopy, Coyuchi and Boll & Branch describe their cloth as brushed or cloud brushed without a side count, and The Company Store’s page doesn’t say brushed (it says “carefully combed to remove impurities”).
Pilling, lint and shrinking
Three of the six pages make a pilling claim, each about its own cloth. Boll & Branch’s FAQ opens “Flannel is often known for pilling, but ours is different” and credits a triple-shearing process with “naturally reducing the appearance of pills”; Coyuchi’s says its flannel is “designed to resist pilling”; The Company Store’s says “pilling less and lasting longer”. Brooklinen’s and Crane & Canopy’s product pages carry no line on pilling, shrinking or lint (our reading). Mellanni’s 180 GSM page says “The fabric resists shrinkage”, the only shrinkage line among the six; the page for its lighter 160 GSM set says “Wash before use. Lint may occur after the first couple of washes.”
Six flannel sets, from the lowest queen price up
Mellanni Flannel Cotton Sheet Set, Heavyweight 180GSM
Best for the highest GSM here at the lowest queen price. The page calls it “180 GSM heavyweight flannel”, double brushed on both sides, and says the fabric resists shrinkage. That is 40 GSM more cloth than Brooklinen’s 140 for about a quarter of the price (our arithmetic). A queen set is a flat sheet, a fitted sheet and two pillowcases. The maker’s lighter 160 GSM set costs $52.27 in queen.
Drawbacks: The page gives two sets of wash and dry lines: cold wash and tumble dry low in the feature list, warm wash and warm or medium heat in the care block. The feature list gives 16 inches, and the size table also lists a 21-inch extra-deep column without saying whether this set comes in it (our reading). The page text says 100% cotton and doesn’t say organic, though the web address contains the word.
The Company Store Classic Ultra-Cozy Cotton Flannel Bed Sheet Set
Best for the lowest price among the three ounce-weighted sets. The page describes velvet-like softness, “pilling less and lasting longer”, and flannel “carefully combed to remove impurities”, made by Portuguese textile makers. Care is a gentle-cycle wash with like colours, with no water temperature given, then tumble dry low and remove promptly. At 5 oz it is the lowest of the three ounce figures here, but those can only be ranked among themselves if they share a basis (our reading).
Drawbacks: The weight is “5 oz.” with no area unit. The queen price depends on colour: $179 in four colours and $199 in twelve others, and one clearance colour lists under $100. The pocket is 14 inches on its size table, so it is not cut for a deep pillow-top (our reading).
Crane & Canopy Soft White Flannel Sheet Set
Best if you sleep without a top sheet. The page says the sheets are “sold as a set with or without the top sheet” and “can also be purchased individually”. It is the same set our best sheets roundup picks for cold sleepers; what this page adds is where its weight sits: 5.6 oz falls between The Company Store’s 5 oz and Coyuchi’s 6-ounce, if the three share a basis (our reading).
Drawbacks: The weight is “5.6 oz” with no area unit, so it can’t be lined up against the GSM sets. The product page has no pilling or shrinkage line. The pocket is 16 inches, too shallow for a deep pillow-top (our reading).
Brooklinen Brushed Flannel Core Sheet Set
Best for a lighter flannel. The maker’s comparison chart sends its brushed flannel to people for whom “If you run chilly or live in a cold climate” fits, and the product text says “At 140 GSM, these sheets are lighter than you’d expect”. The set is OEKO-TEX certified for chemical safety, and king and Cali king sets come with king pillowcases.
Drawbacks: At 140 GSM it is the lighter of the two GSM figures here, 40 GSM under the Mellanni (our arithmetic). The page lists three speckled colours only, and the product page has no pilling or shrinkage line. It fits mattresses up to 16 inches.
Coyuchi Cloud Brushed Organic Flannel Sheet Set
Best for organic cotton. The page calls the cloth “cloud brushed” and the weave and brushing a proprietary process, and says the flannel is “designed to resist pilling and only gets softer with time”. Care is a cold, gentle-cycle wash, tumble dry low, and remove promptly.
Drawbacks: The weight is “6-ounce” with no area unit, so its “Warmer and weightier than traditional flannel” line can’t be checked against another page’s number (our reading). The page gives no pocket depth, so measure the mattress and ask before ordering. It is the second most expensive set here.
Boll & Branch Flannel Sheet Set
Best for the deepest pocket and a pilling answer that names its process. The fitted sheet fits mattresses up to 18 inches in sizes twin XL to California king (16 inches on the twin), and the page describes a “Brushed and tripled sheared” finish for pill resistance. Its FAQ says the flannel is “designed for warmth, but it’s still breathable”, and the page lists it as best for “Cold sleepers, winter months, and anyone who wants cozy warmth without overheating”.
Drawbacks: The most expensive set here, and the page prints no weight number, only “midweight” in its FAQ, so you can’t line it up against the others. The patterned versions cost $299 to $399 in queen. The care line says to avoid bleach and fabric softeners.
How to choose
- Which weights can you actually compare? Only the GSM pair is a straight comparison, Mellanni’s 180 against Brooklinen’s 140. Brooklinen pitches its flannel at people who run chilly and calls the 140 GSM “lighter than you’d expect”, while Mellanni calls its 180 GSM “Ideal for cold nights”; both are the makers’ own words, and the numbers only say the Mellanni is the heavier cloth (our arithmetic). If you run hot rather than cold, see our best cooling sheets instead.
- How much do pills worry you? Three of the six pages make a pilling claim (Boll & Branch, Coyuchi, The Company Store); they are the makers’ claims about their own cloth, not test results. Three pages also steer you off softener: Boll & Branch (“Avoid bleach and fabric softeners”), Mellanni (“Do not use fabric softener as this will pill fibers”) and Coyuchi, which suggests wool dryer balls “in lieu of softeners or dryer sheets”.
- Is your mattress deeper than 16 inches? Five of the six pages give a depth: Mellanni, Brooklinen and The Company Store say the fitted sheet fits mattresses up to 16 inches, Crane & Canopy lists a 16-inch pocket and Boll & Branch says up to 18 inches. The Company Store’s size table puts its pocket at 14 inches. Coyuchi’s page gives none. Measure with the topper on (our suggestion).
- Organic or budget? Coyuchi (“GOTS certified organic cotton”) and Boll & Branch (“100% organic cotton”) name organic cotton; the other four pages say 100% cotton or brushed cotton. At the reference prices here Mellanni is the only set under $100 (The Company Store lists one clearance colour below that), and the other five run from $179 to $349, about three to six times its price (our arithmetic).
- Check the size. The six prices here are queen prices, and a queen is 60 by 80 inches on the Brooklinen, Crane & Canopy and Mellanni charts. Our bed sizes chart has the other sizes.
First wash and care
Each line here is the maker’s own care text: the set’s product page, or for Brooklinen its care guide.
- Cold or warm. Four of the six say cold: Boll & Branch (“Machine wash cold with like colors”), Coyuchi (“Cold wash, gentle cycle with like colors”), Crane & Canopy (“Machine wash cold”) and Brooklinen’s care guide (“Machine wash cold with like colors” for brushed flannel). The Company Store says “Machine wash gentle cycle with like colors” and gives no temperature. Mellanni’s 180 GSM page says cold in its feature list and “Machine wash warm on delicate cycle” in its care block.
- Drying. Boll & Branch says tumble dry low or medium. Coyuchi, Crane & Canopy, The Company Store and Brooklinen’s care guide each say tumble dry low and remove promptly. Mellanni’s page says “tumble dry low” in one place and “warm or medium heat” in another.
- Before the first night. Lint may show after the first couple of washes on Mellanni’s lighter 160 GSM set, and its page says to wash before use. Washing any new set once before it goes on the bed and emptying the dryer’s lint filter afterwards is our suggestion.
Where these numbers come from
Weights, fibres, pocket depths, pilling, shrinkage and care lines come from each brand’s own product page (plus Brooklinen’s care guide for its wash and dry lines), and the counts across the six and the GSM comparison are our own. Prices are the queen prices shown on those pages without a discount code, read on 24 October 2026.
Frequently asked questions
How do I compare flannel weights from different brands?
Compare like units only. Of the six sets here, two print GSM (Brooklinen 140, Mellanni 180) and three print ounces with no area unit (Crane & Canopy 5.6, The Company Store 5, Coyuchi 6); Boll & Branch prints no weight number. None of the ounce figures can be turned into GSM from what those pages print, so ask the brand which area its ounces refer to before lining one up against a GSM figure (our suggestion).
Do flannel sheets pill?
Three of the six pages claim their own flannel resists or reduces it: Boll & Branch (triple-shearing, “naturally reducing the appearance of pills”), Coyuchi (“designed to resist pilling”) and The Company Store (“pilling less and lasting longer”). The Brooklinen, Crane & Canopy and Mellanni 180 GSM pages make no pilling claim, and Mellanni’s care text says not to use fabric softener, “as this will pill fibers”.
Will flannel sheets shrink in the wash?
Only one of the six pages speaks to it: Mellanni’s 180 GSM page says “The fabric resists shrinkage”. The other five carry no shrinkage line (our reading), so follow each maker’s wash line, which is cold on four of the six.
Which of these flannel sets fits a deep mattress?
Boll & Branch’s queen set is cut for mattresses up to 18 inches. Mellanni’s feature list, Brooklinen and The Company Store say up to 16 inches (The Company Store’s size table puts its pocket at 14 inches), and Crane & Canopy lists a 16-inch pocket; Coyuchi’s page gives no depth, and Mellanni’s size table also lists a 21-inch extra-deep column without saying whether this set comes in it (our reading). Measure the mattress with any topper on before ordering (our suggestion).
