Cooling Weighted Blanket for Hot Sleepers

It comes down to construction rather than fabric. To keep glass beads or plastic pellets from shifting, they have to be sealed inside sewn pockets between two continuous layers of fabric. Those layers cannot have gaps, or the fillers escape. 
BloomKnit™ is a knitted weighted blanket, hand-knit from thick cotton loops with open space between them, so air moves through the blanket itself.
Hold it up to a lamp and you can see light through the gaps. How much difference that makes will depend on your room and your bedding, but the airflow is something you can see rather than something you have to take on trust.

The 15 lb (45" x 72") is what most people choose, and it is the easier starting point if you have never used a weighted blanket. The 20 lb (48" x 72") gives a heavier, more grounded feel and is usually preferred by people who already know they like substantial weight. If you are between the two, choose 15 lb for gentler pressure and 20 lb for a heavier feel. These are comfort preferences, not medical guidance.

The experience you’ll have with a weighted blanket can vary quite a bit depending on your body frame, height, and personal comfort preferences. Most people find that the 15 lb size is a good fit for average sleepers, especially if you’re on the petite side or just starting out with weighted blankets. However, the sensation of weight is different for everyone, what feels gently grounding to one person might feel a bit much to someone with a smaller frame or less need for heavy pressure.

If you’re particularly petite or sensitive to heavier covers, you might notice that a 20 lb blanket feels too substantial, especially when shifting positions at night. On the other hand, if you’re taller or have a larger build, you might prefer the slightly more anchored feel of the 20 lb version. One thing to note: the dimensions of each size can differ, so taller individuals should check the length if full coverage is important.

Because BloomKnit™ uses an open-knit structure, there’s increased airflow, so whether you choose the lighter or heavier weight, you won’t feel stuffy or overheated. Some people even add a light cotton sheet underneath during colder nights, but most find the blanket comfortable through seasonal changes. In the end, think of the right weight as a blend of your height, frame, and how much deep touch pressure you actually want. If you’re between sizes or not quite sure - starting lighter is usually the more versatile choice.

Yes, they can. The loops are large and open, and that is what creates the airflow. Most people find it unremarkable or even like it. If you want a blanket with a closed surface, an open knit is not the right style for you. Weighted blankets are not suitable for infants or young children, and BloomKnit™ should not be used in a crib or with a child who cannot easily move it off themselves.

The cotton is knit into thick continuous strands rather than woven from short fibers, so it does not shed the way a fleece or chenille blanket does. Like any knit, it will relax slightly with use and settle into its own drape. Washing it in the cotton bag provided and drying it flat or on low keeps the loops even.

We do not recommend it. At 45" x 72" and 48" x 72", BloomKnit is sized to fit your body, not your mattress. Weighted blankets are designed to sit on one person so the weight stays evenly distributed. Shared between two people, the weight pulls unevenly and tends to slide off. Couples who both want one usually buy two.

Machine wash cold in the cotton wash bag provided, on the bedding cycle. Tumble dry low. Never hang it while wet, since the weight of the water will pull the loops out of shape.

Customers consistently highlight several benefits of weighted blankets, especially the open-knit cotton varieties:

Pros:

• Cooling comfort: Most users say the breathable, open-knit design prevents overheating and keeps them cool all night - an especially big upgrade over standard weighted blankets filled with glass beads or polyester.
• Even weight distribution: The gentle pressure is described as relaxing and evenly spread, making it easier to fall asleep and stay asleep.
• Quality and appearance: Many appreciate the soft feel, attractive look, and solid construction - the kind you’d expect in thoughtfully designed home goods.

Cons:

• Sizing and weight preferences: Some reviewers mention it takes trial and error to find their ideal blanket weight, and a few wish for larger dimensions to cover more of their bed.
• Color options: A handful of customers have noted they’d like a broader palette to match individual decor needs.

Overall, the general consensus is that the cooling effect and comfort of a knit weighted blanket stand out, though availability of sizes and colors can be limiting for some shoppers.
