Crisp percale is perfect for most of the year, but when the thermostat drops, nothing feels quite like sliding into flannel. The fabric is brushed (or “napped”) to raise tiny fibers that trap warm air, so the bed feels warm the moment you get in.
To find the best flannel sheets, we combined two independent, hands-on evaluations. The Good Housekeeping Institute Textiles Lab has tested more than 300 sheet sets in recent years, including plenty of flannel, measuring fabric strength, pilling, shrinkage and wrinkling and sending sets to consumer testers. CNN Underscored’s Joe Bloss slept in eight flannel sets, washing them repeatedly over months, and judged feel, weight, durability, fit, sizing and return policies. We didn’t test these sheets ourselves; we report what those testers found.
Quick answer: Garnet Hill’s Hemstitched Supima (Pima) Cotton Flannel is the top pick of both Good Housekeeping and CNN Underscored. For a budget set sold on Amazon, Good Housekeeping’s best value is the Mellanni Cotton Flannel Sheet Set. Hot sleepers and early-autumn sleepers should look at the lighter Brooklinen Flannel Core set, and Boll & Branch is the organic splurge.

How we chose
We prioritized sets that performed well in lab testing or long-term sleep testing, especially the one both outlets named best overall. Then we compared what matters most for flannel: fabric weight (the best proxy for warmth), softness after washing, pilling and shrinkage, pocket depth, size and color range, whether pieces can be bought separately, and return policies. Where a set is sold on Amazon, we link there; otherwise we link to the brand.
What makes flannel warm (and why thread count doesn’t matter)
Weight, not thread count. CNN Underscored advises ignoring thread count on flannel and looking at weight, measured in ounces per square yard or grams per square meter (GSM). Good Housekeeping says heavier is generally warmer and suggests at least 5 ounces per square yard (about 170 GSM) if you want a cozier fabric. CNN calls 6 ounces (roughly 200 GSM) a proper weight for the thickness and warmth most people want.
Cotton vs. polyester. Most flannel sheets are 100% cotton. Good Housekeeping notes polyester flannel is cheaper, more durable and easier to wash, but less breathable and likely not as soft.
Pilling is normal. Both outlets saw pilling on flannel. CNN explains that the brushing process that makes flannel soft raises fibers that can tangle into small pills; it doesn’t affect performance.
Organic claims. Good Housekeeping recommends looking for GOTS certification, which covers the whole production process, because organic claims are often misused in bedding.
The best flannel sheets
1. Garnet Hill Hemstitched Supima Flannel Bedding: best overall
Best for: anyone who wants the warmest, softest flannel.
This is the rare product two independent testers agree on. Good Housekeeping calls it its best overall flannel: the Supima cotton earned high scores in Lab fabric-strength tests, and in its newer softness testing it received a perfect 5/5 softness score from blinded testers. One tester said the sheets are “deliciously soft to the touch, like a giant cuddle when you get in bed each night.”
CNN Underscored also named it the best of eight sets. Joe Bloss found it the heaviest flannel he tested at 6 ounces (most were around 5), said it got softer with washing, and liked that every piece is sold separately, so you can skip the top sheet or add pillowcases. CNN notes it’s made in Portugal from US-grown pima cotton, comes in sizes from twin to California king, and that the brand’s return policy excludes used sheets.
Pros
- Heaviest, warmest weight in CNN’s test
- Perfect softness score from GH testers
- Pieces sold separately; monogramming available
Cons
- Some wrinkling out of the dryer
- Pills like all flannel
- Strict return policy for used sheets

2. Mellanni Cotton Flannel Sheet Set: best value
Best for: budget shoppers and thick mattresses.
Good Housekeeping’s best value pick is sold on Amazon and proves you don’t have to splurge, according to GH. At 5 ounces it’s a touch lighter than Garnet Hill’s 6, which GH says keeps you warm without feeling too thick or heavy. Consumer testers praised its cozy feel.
It didn’t do as well in Lab durability tests, but it beat other flannel sets for wrinkle resistance. GH lists 16-inch pockets, sizes from twin through California king, and 10 colorways.
Pros
- Affordable
- 16-inch pockets
- Wrinkle resistant for flannel
Cons
- Less durable in Lab tests
3. Brooklinen Flannel Core Sheet Set: best lightweight
Best for: warm sleepers and transitional seasons.
Good Housekeeping’s consumer testers gave this set top scores for softness, comfort and warmth, and its Lab wrinkle-resistance scores were the highest GH says it has seen for flannel. Testers also liked the “short side” and “long side” tags on the fitted sheet.
It’s light, though. CNN Underscored measured it at 140 GSM, about 4 ounces, and found it soft and comfortable but not a heavy, insulating layer for frigid nights; it worked best in early autumn with the windows open. Brooklinen also runs an official Amazon store.
Pros
- Very wrinkle resistant
- Labeled fitted-sheet sides
- Good for warmer sleepers
Cons
- Lightest set here, so less warmth

4. Boll & Branch Flannel Solid Sheet Set: best organic splurge
Best for: shoppers who want certified organic cotton.
Good Housekeeping calls this set the cream of the crop for those willing to splurge. It’s GOTS-certified organic, made with long-staple cotton that testers called “so cozy” and “great for winter,” and its pockets run 16 to 18 inches depending on size. It wasn’t the most durable in GH’s Lab tests. GH notes a 30-day, no-questions-asked return policy. Boll & Branch also sells through an official Amazon store.
Pros
- GOTS-certified organic
- Deep pockets
- Buttery soft
Cons
- Lower Lab durability scores
- Expensive

5. Coyuchi Cloud Brushed Organic Flannel Sheet Set: best heavyweight organic
Best for: people who want weight and a velvety hand.
Good Housekeeping found this heavy, GOTS-certified set durable, with less shrinkage than other flannel it tested, but its velvety feel was polarizing: some testers loved it, others found it too warm. CNN Underscored, which also tested it at 6 ounces, found it stiffer at first and said it loosened with washing but never got as soft as Garnet Hill.
Pros
- Heavy and warm
- Low shrinkage in GH tests
- Muted colorways
Cons
- Polarizing feel
- Stiffer at first

6. Crane & Canopy Flannel Sheet Set: a heavy alternative
Best for: cold bedrooms and monogram fans.
CNN Underscored found this 5.6-ounce set significant and best for colder settings, with a fuzzy texture that was soft but not abundantly so. It costs about the same as Garnet Hill. The fitted sheet’s tag marks the bottom-right corner for easier bed-making, replacements are sold individually, and CNN notes $10 custom monograms. It comes in just three colors.
Pros
- Heavy weight
- Easy bed-making tag
- Replacement pieces
Cons
- Only three colors

7. The Company Store Flannel Sheets: best mid-weight
Best for: warmer sleepers who still want flannel.
At 5 ounces, these sit between Garnet Hill and Brooklinen, which CNN Underscored calls a sweet spot for warmer sleepers. They were among the softest sets CNN tested, and replacements are easy to buy. CNN says they’re often discounted at The Home Depot.
Pros
- Very soft
- Middle-of-the-road weight
- Often on sale
Cons
- Lighter than the warmest picks

8. Laura Ashley Flannel Sheet Set: best for prints on a budget
Best for: kids’ rooms, guest rooms and festive bedding.
CNN Underscored says you won’t mistake this set for a $200 one: it has no advertised weight, feels light and has a slightly loose fitted-sheet elastic. But it’s soft, costs a fraction of the others, and the print selection, from florals and plaids to dogs in Santa hats, beat every other brand CNN tested.
Pros
- Low price
- Huge range of prints
Cons
- Light; loose elastic
How to choose flannel sheets
- Pick a weight for your climate. About 4 ounces is light flannel; 5 is mid-weight; 6 is heavy. GH suggests 5 ounces or more for real coziness.
- Check pocket depth. Good Housekeeping recommends confirming the fitted sheet’s maximum depth if you have a thick mattress or a topper.
- Think about replacements. CNN valued brands that sell pieces individually so you can add pillowcases or replace a worn fitted sheet later.
- Budget sensibly. Good Housekeeping’s experts say $100 to $200 is the sweet spot for value and quality, with worthwhile options above and below.
- Read the return policy. CNN notes some brands won’t accept used sheets, which matters for a fabric you have to sleep on to judge.
Care tips
CNN Underscored found care straightforward: wash cold or warm with like colors (check the label), dry on low heat, and empty the lint trap after every cycle, since every flannel set shed plenty of fuzz. Expect some pilling in the first few washes. To build a warmer bed, layer flannel under a warm down comforter or add one of our heated mattress pads.
FAQ
Are flannel sheets good for hot sleepers?
Not really. CNN Underscored says flannel is better at retaining heat than cooling you down. If you run hot, try a lighter flannel like Brooklinen’s, or stick with percale or linen.
What is a good weight for flannel sheets?
CNN considers 6 ounces (about 200 GSM) a proper weight for warmth; Good Housekeeping suggests at least 5 ounces per square yard (about 170 GSM) for a cozier fabric.
Why do flannel sheets pill?
Flannel is brushed to raise soft fibers, and those fibers can tangle into pills. Both outlets saw pilling on every flannel set; it’s normal and doesn’t affect warmth.
Is flannel the same as cotton?
Flannel is a finish, not a fiber. Good Housekeeping notes most flannel sheets are 100% cotton, though polyester versions exist.
The bottom line
If you want the coziest flannel and are willing to pay for it, buy Garnet Hill’s Supima set; both Good Housekeeping and CNN Underscored put it first. For value, Mellanni’s set on Amazon is GH’s pick. Choose Brooklinen if you want lighter warmth, and Boll & Branch or Coyuchi if certified organic cotton matters to you.
