Why BloomKnit™: The Breathable Weighted Blanket for Hot Sleepers
TL;DR: BloomKnit™ is a hand knit, 100% cotton weighted blanket from Blanket & Bloom. There are no glass beads, no plastic pellets, and no synthetic fillers anywhere inside it. The weight comes from the cotton itself, knit into a dense open stitch that lets air move through the blanket instead of trapping it against your body. It comes in 15 lb and 20 lb adult weights and six colorways, it machine washes at home, and it is made to sit on the bed rather than hide under a duvet. If you bought a weighted blanket and quietly stopped using it because you woke up sweating, this is the one that fixes that.
What Is BloomKnit™?
BloomKnit™ is the proprietary fabric and construction method Blanket & Bloom developed for its weighted blankets. The name covers both the material, a chunky 100% long-staple cotton yarn, and the technique, an oversized hand knit that creates weight through density rather than added fillers.
Every BloomKnit™ blanket is hand knit start to finish by a single craftsperson. No internal beads. No quilted pockets. No synthetic backing. No plastic of any kind. It is pure cotton inside and out, and the weight comes from the cotton itself.

Why Most Weighted Blankets Get Abandoned
Walk through how a conventional weighted blanket is built and the problem explains itself. A quilted polyester or nylon casing is divided into small squares. Each square is packed with glass beads or plastic pellets. Then the whole thing is sewn shut.
That construction creates three problems that no amount of marketing solves.
It traps heat. Sealed synthetic pockets are the opposite of airflow. Body heat builds against your skin with nowhere to go, and it gets worse under a duvet or in a warm room. This is the single most common reason weighted blankets end up in the closet.
It puts plastic against you all night. Glass beads are inert, but they live inside synthetic casing, and worn or torn pockets leak into the wash.
It shifts, clumps, and rustles. Beads slide toward the low spots. You hear them move when you move. And because most bead blankets look like medical equipment, people hide them under bedding, which makes the heat problem worse.
For anyone navigating menopause, living somewhere warm, or simply running hot at night, those tradeoffs are usually the end of the story.
How BloomKnit™ Solves It
BloomKnit™ removes the bead-and-pocket construction entirely. There is nothing sealed inside, because there is no inside.
The material
100% long-staple cotton. No polyester blends, no chenille, no recycled synthetics, no hidden core. Cotton is breathable and absorbent by nature, which is exactly what sealed synthetic casing prevents. Long-staple fiber also means a smoother, stronger, longer-lasting yarn than standard cotton.
The construction
Each blanket is hand knit on oversized needles in a dense stitch developed specifically for weighted bedding. No quilted seams. No glue. No internal pockets. The construction is the weight.
The airflow
This is the difference you feel on night one. The open knit lets air circulate through the blanket rather than pool on top of you. That is why BloomKnit™ works in July, in a warm bedroom, and layered over an existing duvet, in situations where a bead blanket is simply unusable.
The pressure
Because weight is built into the fabric instead of concentrated in quilted squares, pressure distributes evenly and the blanket conforms to your body as you move. The deep pressure stimulation feels like a steady, full-body hug rather than a stack of small weights sitting in the wrong places.
BloomKnit™ vs Traditional Weighted Blankets
| Feature | BloomKnit™ | Traditional Weighted Blanket |
|---|---|---|
| What creates the weight | The cotton yarn itself | Glass beads or plastic pellets |
| Material | 100% long-staple cotton | Polyester or nylon casing, plastic fillers |
| Airflow | High, open knit circulates air | Low, quilted and sealed pockets |
| Hot sleepers | Designed for them | Often unusable |
| Construction | Hand knit by one craftsperson | Machine quilted, mass produced |
| Weight feel | Even, draping, conforming | Concentrated in pockets, heavy spots |
| Noise | Silent | Shifting and rustling beads |
| Care | Machine wash cold at home | Often requires a separate removable cover |
| Look | Visible texture, made to be seen | Hidden under a duvet |
| Plastic content | Zero | Synthetic casing and plastic fillers |
Who BloomKnit™ Is For
Hot sleepers who already tried a bead-filled blanket and gave up on it. This is the version that survives summer.
Adults managing night sweats and temperature swings, including through menopause, who want weight without the heat that comes with conventional construction.
Light sleepers who want the calm, grounded feeling of deep pressure stimulation without beads shifting and rustling every time they turn over.
Couples who share a bed and want a weighted blanket that does not have to be hidden. BloomKnit™ is designed to live on the bed.
Anyone in a warm climate where traditional weighted blankets were never realistic in the first place.
Anyone who cares what their bedroom looks like. BloomKnit™ reads as a textile piece, not a therapy device.
Which Weight Should You Choose?
BloomKnit™ comes in 15 lb and 20 lb.
- 15 lb is the more forgiving choice. Pick it if you are new to weighted blankets, if you shift positions a lot at night, or if you want noticeable pressure that still moves easily with you.
- 20 lb is for people who already know they like weight, or who tried a lighter blanket and wanted more.
Both weights use the same cotton and the same knit, so the airflow is identical. Only the density of the pressure changes. Use the weight guide on the product page if you want a recommendation for your body.
Weighted blankets are for adults. They are not recommended for children under three, and anyone with a respiratory or circulatory condition should check with a doctor first.
How BloomKnit™ Is Made
Every blanket is hand knit start to finish by a single craftsperson. No machine seams, no glue, no plastic, no synthetic backing.
Slight variation in texture, stitch tension, and finished dimension is normal and expected. That is the signature of something made by hand, not a defect.
It also means BloomKnit™ is not a mass production item. We knit to demand rather than warehousing inventory, so quantities in each colorway are limited.
Care and Longevity
BloomKnit™ is built to last years, and it washes at home.
- Machine wash cold in the cotton wash bag included with your blanket, on your machine's bedding cycle
- Dry flat, or tumble dry on low
- Never hang the blanket while wet
- Dry cleaning is also fine
- Store folded rather than hung
- Spot clean spills with cold water and a mild detergent
- Light shedding in the first few weeks is normal and stops with use
There are no pockets to tear, no fillers to leak, and no synthetic casing to pill, which is why a well-cared-for BloomKnit™ outlasts the bead blankets it replaces.

Pair It With DreamSilk™
For a complete sleep setup, pair BloomKnit™ with the DreamSilk™ mulberry silk pillowcase. Silk is smooth, breathable, and gentle on skin and hair, and it complements the cotton knit rather than fighting it. Together they make The Dream Duo, the only weighted bedding pairing built specifically around hot sleepers.
Frequently Asked Questions
Is BloomKnit™ as heavy as a regular weighted blanket? Yes. BloomKnit™ comes in 15 lb and 20 lb adult weights, directly comparable to bead-filled blankets. What changes is how the weight feels: draping and evenly distributed instead of pocketed.
Will a cotton blanket still feel too warm? No. Cotton is breathable on its own, and the open BloomKnit™ knit lets air move through the blanket instead of trapping it against your body. It is dramatically cooler than a quilted bead-filled blanket and noticeably cooler than synthetic knit alternatives.
What is inside a BloomKnit™ blanket? Nothing. There is no interior compartment. No glass beads, no plastic pellets, no synthetic fillers. The weight comes from the cotton itself.
Can I wash it at home? Yes. Machine wash cold in the included cotton wash bag on a bedding cycle, then dry flat or tumble dry low. Never hang it while wet. No separate removable cover is needed.
Is BloomKnit™ safe to use every night? Yes, for adults. It is designed for nightly use. Weighted blankets are not recommended for children under three, and anyone with a respiratory or circulatory condition should speak to a doctor first.
How is BloomKnit™ different from Bearaby or other knit weighted blankets? Three ways. BloomKnit™ is 100% cotton throughout, with no polyester core, velvet, or recycled synthetics inside the yarn. It uses a denser hand knit stitch developed specifically for warm sleepers. And it is built and finished as a luxury piece rather than a wellness commodity.
Does it look like a weighted blanket? No, and that is deliberate. BloomKnit™ is meant to be seen: draped across a bed or sofa as a textile, not hidden under a duvet.
How long does it last? Years, with basic care. No pockets to tear, no fillers to leak, no synthetic casing to pill.
Ready to Sleep Under It?
If you have already tried a weighted blanket and quietly stopped using it, the blanket was not the problem. The construction was. BloomKnit™ gives you the weight without the heat, in cotton you can actually leave on the bed.
