Can PillowWeights be used indoors?

Yes. PillowWeights work indoors or outdoors on any square or rectangular pillow from 12x12 up to 24 inches. They are completely undetectable inside the pillow cover and do not affect the comfort or appearance of the pillow.

Are PillowWeights machine washable?

The insert itself should be spot-cleaned only. However, if the PillowWeight is permanently installed inside a pillow cover, the entire pillow can be machine washed on a gentle cycle. The fastening strips are machine wash and machine dry safe.

What is the weight of each PillowWeight insert?

Each PillowWeight insert weighs exactly 1 pound (16oz). The weight comes from premium microglass beads — not metal plates or rigid inserts — so the weight is soft, flexible, and distributed evenly across the 10x10 inch insert.

What pillow sizes do PillowWeights work with?

PillowWeights fit square pillows from 12x12 up to 24x24 inches, and rectangular pillows including 12x20 and 14x24 inches. For pillows larger than 24 inches, we recommend two PillowWeights for full 50mph wind coverage. The insert itself is 10x10 inches and contours to the shape of the pillow.

How do I install PillowWeights?

Installation takes under one minute and requires no tools. Step 1: Remove the pillow from the cover and flip the cover inside out on a flat surface. Step 2: Attach the included fastening strips to the PillowWeight along the velcro square. Step 3: Center and press the adhesive side of the PillowWeight onto the back interior of the pillow cover. Replace the pillow and enjoy.

Are PillowWeights weather resistant?

Yes. The shell is made from UV-resistant, water-resistant ripstop nylon rated for long-term outdoor exposure. PillowWeights hold up through rain, sun, and daily outdoor use. They are wind tested to 50mph using a calibrated anemometer — documented with video proof.

Do PillowWeights work with all pillow shapes?

PillowWeights work with square and rectangular pillow shapes. The 10x10 inch insert fits square pillows from 12x12 to 24x24 inches and rectangular pillows including lumbar sizes like 12x20 and 14x24 inches. Circular or bolster pillow shapes are not currently supported.

Do you offer custom sizes?

Custom sizes are coming in 2026. Currently PillowWeights stocks one universal size — the 10x10 inch insert — which covers the vast majority of standard outdoor pillow sizes from 12 to 24 inches.

Do you ship internationally?

Yes, PillowWeights ships internationally. International buyers are responsible for the full shipping cost. Domestic US orders ship free.

Do you offer trade and wholesale accounts?

Yes. PillowWeights services trade and wholesale accounts including interior designers, hotels, property management companies, and hospitality groups. Register at pillowweights.com/pages/trade-account-registration.

How to Install Your PillowWeight

Installation

Two ways to install. Both take about a minute.

A PillowWeight is a hidden, soft textile insert that anchors inside your outdoor pillow cover and keeps the pillow from blowing away. It installs with a fastener system we engineered to lock in and stay put. Here is how it works, and the two surfaces you can anchor it to.

Watch first

One minute, the whole install, start to finish.

See how the strips go on, how the weight bonds inside the cover, and how the pillow looks once it is anchored.

Filmed in 4K. Just over a pound, distributed across 16 internal sections so it lies flat and stays invisible from above.

How it anchors

A fastener system that locks in and stays.

Every PillowWeight has four hook-fastener squares, one in each corner, and ships with four matching strips. Each strip is a baby-soft loop fastener bonded to a professional-grade transfer adhesive. You marry the two, then bond the weight to the inside of your cover.

1. Soft loop, meet hook

Press one strip onto each of the four hook squares on the weight, soft side down. That leaves the strong adhesive side facing up and ready to bond.

2. Bond to the cover

Center the weight, adhesive side down, on the inside of your pillow cover and press firmly. The four corners anchor it flat and square.

3. It is not going anywhere

The PillowWeight will not shift or slide. The hook-and-loop lets you lift the weight off later to launder the cover, while the strips stay bonded in place.

Built to stay: the soft loop fastener pairs with a professional-grade performance adhesive engineered to bond textile to fabric and hold. Once it cures, your PillowWeight sits exactly where you placed it, gust after gust, season after season.

The two methods

Same system. Two surfaces you can anchor to.

The fastener system works the same way either way. The only choice is which interior surface you bond the weight to, and that comes down to how your cover is cut.

Method 1

Anchor it to the cover

Bond the weight to the rear interior of the pillow cover

Turn the cover inside out and bond the weight to the back inside wall of the cover itself.

Pulls the looser areas of the cover tighter around the insert
Gives an even, taut, perky presentation
Distributes the weight evenly across the back of the pillow
Works beautifully on covers that are slightly relaxed or generously cut

Good for: most outdoor pillows, and any cover that is a touch loose around the insert.

Method 2

Anchor it to the insert

Bond the weight to the rear of the pillow insert

Bond the weight to the back of the pillow insert itself, then slide the insert into the cover as one piece.

The most seamless, invisible installation of the two
Nothing bonds to the decorative cover at all
The weight travels with the insert, so the pillow holds its exact shape

One note: we suggest this method only for perfectly fitted pillow covers. On a loose or oversized cover, anchoring to the insert lets the cover drift around the weight, so Method 1 will look better there.

Good for: tailored, true-to-size covers where the insert fills the cover completely.

Both methods hold exactly the same way in the wind. We don't push one over the other, it is simply about the look you want and how your particular cover is cut.

Step by step

Installing in about a minute.

Turn the cover inside out. Remove the insert, turn your outdoor pillow cover inside out, and lay it face down on a hard, flat surface.

Attach the four strips to the weight. Press one strip onto each of the four hook squares on the PillowWeight, soft side down. The adhesive side is now facing up.

Bond it in place. Center the weight, adhesive side down, on the inside of the cover (or on the rear of the insert for Method 2). Press very firmly along each square, then flip and press from the other side too.

Reassemble. Turn the cover right side out, slide the insert back in, and place the pillow. It looks like a normal throw pillow, now it just stays put.

One thing to remember: leave the bond undisturbed and don't wash for 72 hours so the transfer adhesive can fully cure. After that, it is set for the long haul.

Good to know

Hidden, soft, and locked in.

Completely hiddenIt lives inside the cover, invisible from every angle once installed.

Soft, not rigidNylon ripstop shell with microglass bead fill. No hard blocks or plates, the pillow still feels like a pillow.

Built for weatherWater resistant and UV resistant. In testing, our pillows held through constant winds around 45 mph, with shorter gusts higher still.

WashableLift the weight off the loop strips, launder the cover with the strips still attached, then press the weight back on.

A quick note for safety: PillowWeights are not a toy. Do not cut open. Keep away from children and pets if the shell is damaged. Use only inside outdoor pillow covers, and discontinue use if the shell is ever torn or leaking. Inspect the cover and insert periodically. Fits the most common throw-pillow sizes, from 12" x 12" to 20" x 20" and rectangular sizes within that range.
