Is the Gravity Blanket duvet cover machine washable?

Yes, the removable microfiber duvet cover is machine washable on a normal cold cycle. The weighted insert itself, the part containing the glass beads, should be spot cleaned or hand washed rather than machine washed, since repeated full machine washing puts stress on the internal seams over time.

What weight Gravity Blanket should I buy?

Use roughly 10 percent of your body weight. Gravity offers 15, 20, and 25-lb versions, so a 150-pound adult fits the 15-lb version well, a 200-pound adult the 20-lb, and anyone over about 220 lbs can consider the 25-lb top weight. When between two sizes, sizing down is generally the more comfortable choice.

Does the Gravity Blanket run hot?

Yes, more than knit alternatives like the Bearaby Cotton Napper. The cotton inner shell breathes better than an all-polyester fill, but the sealed quilted bead pockets still trap more heat than an open-knit design. Hot sleepers should consider a lighter weight or keep the bedroom a few degrees cooler than usual.

How long do the internal seams on a Gravity Blanket typically last?

Based on long-term owner reports, most Gravity Blankets hold up for several years of regular use before any seam issues appear, provided the duvet cover, not the weighted insert, is what goes through the washing machine regularly. Spot cleaning the insert itself rather than machine washing it extends its usable life.

Gravity Blanket Review: The Original Weighted Blanket Tested

The Gravity Blanket is the product that brought weighted blankets into the mainstream. We tested the 20-lb version's pressure distribution, cover system, and washability to see whether it still holds up against newer competitors.

The Gravity Blanket was one of the first products to make weighted blankets a mainstream bedroom item rather than a niche therapy tool, and years later it is still one of the most recognizable names in the category.

At $90 to $130 depending on weight and color, the 20-lb version tested here uses fine-grade glass beads in small quilted pockets, a cotton inner shell, and a removable microfiber duvet cover with a button-fastening system.

In testing, the small quilted pockets kept weight distributed evenly across the whole blanket, no bunching toward one corner even after weeks of regular folding and use.

The button-fastening duvet cover is a genuinely practical detail, it goes back on after washing far more easily than a full zipper enclosure on some competing brands.

Its main limitation is heat. The cotton shell breathes better than synthetic fill, but the sealed bead pockets still trap noticeably more warmth than an open-knit blanket like the Bearaby Cotton Napper.

What You Are Buying

The Gravity Blanket ships as two pieces, the weighted insert and a removable duvet cover, sold together as a set. It comes in 15, 20, and 25-lb weights at 48x72-inch twin/single dimensions.

The weighted insert is made from a cotton shell filled with fine-grade glass beads sewn into small, evenly spaced pockets, the same basic construction philosophy used across most of this category. The duvet cover attaches with a row of buttons along one edge rather than a zipper.

Performance

Pressure distribution: Across a full night of use, pressure felt consistent from shoulders to feet, with no noticeable shifting of beads toward one section of the blanket, even after the blanket was folded and stored between uses.

Temperature: Sleeping under the 20-lb version in a 68 degree room felt comfortably warm within the first 20 minutes, and noticeably warmer than the same session under the Bearaby Cotton Napper at a similar weight. In a room above 72 degrees, the Gravity Blanket ran warm enough to be uncomfortable for a hot sleeper.

Washability: The duvet cover went through five machine wash and dry cycles during testing with no visible wear on the button fastening or fabric. The weighted insert was spot cleaned rather than machine washed, per the care instructions.

Durability: No seam issues or bead leakage after several weeks of nightly use, consistent with the pattern in long-term owner reviews for this brand.

What It Does Well

The even pressure distribution is the headline strength here, small quilted pockets are simply a well-proven construction and Gravity executes it reliably. The removable duvet cover with button fastening also stands out as a genuinely convenient feature relative to some competitors that require a full zip enclosure or do not separate at all.

What Falls Short

Heat retention is the clearest downside. This is a sealed, quilted bead blanket, and it runs warmer than the Bearaby Cotton Napper's open knit in every side-by-side comparison. There is also no dedicated cooling-fabric version currently available from the brand, unlike some competitors that sell a lyocell or bamboo-blend cover option.

Who Should Buy It

The Gravity Blanket is right if: you want a well-tested, evenly weighted blanket from an established brand, value a removable and easily washable duvet cover, and are not primarily concerned with running hot at night.

Consider alternatives if: you sleep hot and want an open-knit design (Bearaby Cotton Napper), or you want a lower price at a similar construction quality (YnM).
