The basics most guides get right (kept short)
A calming donut is faux fur over loose polyester fill, and both parts respond to the same rules. Wash it every two to four weeks in a normal home; go weekly if someone has allergies or the bed starts to smell. Between washes, run a vacuum over the surface. Pulling out hair and dander does most of the cleaning work and lets you launder less often, which spares the fur.
Check the size before you stuff the whole thing in the machine. Small donuts (roughly 23–24") are usually built to be washed whole. Beds around 30" and larger are cover-only: unzip the faux fur cover, wash that, and leave the fill insert dry. Washing a big insert waterlogs the fill and is where most of the "it never recovered" complaints come from. If you're unsure which size band your bed sits in, our size guide lays out the diameters.
The re-fluff protocol (the part everyone leaves out)
Faux fur doesn't fluff itself. The dryer does the fluffing, and it needs help. Here is the recipe that reliably brings the pile back after a wash:
- Set low or no heat. Use the low, delicate, or air-fluff setting. High heat can singe and permanently curl synthetic fur, and it's not what lofts it — the tumbling is.
- Add two or three wool dryer balls (clean tennis balls work too). They bounce through the bed, break up wet fill, and slap the fur fibers apart as it dries.
- Run about 20–30 minutes for a cover, longer for a small whole bed that came out heavy with water.
- Pause at the halfway mark. Pull the bed out, shake it hard, and push the fill back into an even layer with your hands. This is the single highest-impact move: it stops the fill from drying in one clumped corner.
- Finish the cycle, then check. If a spot is still damp or flat, run another short cycle with the balls. Faux fur that's fully dry and tumbled looks and feels close to new; faux fur pulled out damp will set stiff.
Once it's dry, a quick brush over the surface with a soft pet slicker lifts the pile the rest of the way. That's the whole trick to keeping a donut bed fluffy instead of watching it go crunchy after the first wash.
Rim rescue: fixing a flat or lumpy bolster
The raised donut rim is the part that suffers most in the wash, and it's the complaint we see most: the sides "went flat" or turned into hard lumps while the center stayed fine. Here's why. The bolster is a fabric tube packed with loose fiber. When it gets soaked and tumbled, that fill floats free, migrates, and settles in bunches, so instead of an even ring you get a couple of dense clumps and long deflated stretches. The fill isn't lost. It's bunched, and it needs to be redistributed.
Step-by-step rim restore
1. Find the clumps by feel. Run the rim through your hands and you'll feel dense knots separated by empty sections.
2. Break them up through the fabric. Pinch and knead each clump with your fingers, from outside the cover, until it loosens into fluff again. Work it along the tube toward the flat spots.
3. Tumble with the balls. Put it back in the dryer on low with the dryer balls for another 15–20 minutes. The balls finish separating what your hands started.
4. Shape it while slightly damp. Pull the bed out just before it's bone dry and massage the rim back into an even, rounded ring, coaxing fill from the fat spots into the thin ones. Let it finish drying in that shape. Damp fill holds where you push it; dry fill fights back.
For a bed with a fully removable fill insert, you can open the zipper and hand-redistribute the fiber directly, which is faster and more thorough than working through the fabric. That's one quiet advantage of refillable designs.
The honest wash-count reality
Re-fluffing recovers most of the loft, not all of it. Every wash-and-dry cycle mats the fur a little more and lets some fill compress for good, so a bed that's been laundered a dozen times will feel thinner than a new one no matter how carefully you dry it. That's normal wear, not a defect. When a bed stops bouncing back:
- If it's refillable (FurHaven's cuddler is the common example), buy a bag of polyester fill and top up the rim and center. This is far cheaper than replacing and restores most of the original height.
- If it's a sealed one-piece and the fill is flat and clumped past rescuing, it's usually time to replace. Sewn-in fill has no service life left once it's compressed.
Fixing matted fur on a bed you can't submerge
Sometimes the fur is matted but the bed doesn't need a full wash, or the insert is too bulky to launder. You can groom faux fur back to life dry:
- Work over the dry fur with a pet slicker or pin brush, short strokes, teasing the matted tufts apart. Don't yank; lift and separate.
- Follow with a hair dryer on cool, low airflow, brushing as you go. The moving air lifts the pile the way the dryer's tumble would.
- For a light freshen-up, wipe the surface with a barely-damp cloth, then brush and cool-dry.
One rule underpins all of this: never use fabric softener or dryer sheets on faux fur. They coat each fiber with a waxy film that mats the pile and kills the loft — the opposite of what you're after. Skip them in the wash and the dryer both.
Detergent and machine settings that don't wreck the pile
| Step | Do this | Why |
|---|---|---|
| Detergent | Mild, fragrance-free, small amount | Scented and heavy detergents leave residue that stiffens fur |
| Fabric softener | None, ever | Coats fibers, flattens loft, causes matting |
| Water & cycle | Cold, gentle/delicate | Heat and hard agitation break down fur and seams |
| Protection | Mesh laundry bag, or wash cover inside-out | Shields the pile from snags and pilling |
| Machine | Front-load, or top-load without a center agitator | Agitator posts can tear covers and shred seams |
| Drying | Low/no heat + dryer balls | Restores loft; air-dry alone leaves faux fur matted |
If your only machine is a top-loader with an agitator, put the cover in a mesh bag and use the gentlest setting, or hand-wash in the tub. It's slower but it saves the seams.
Which beds survive washing best
Construction decides how well a bed ages through the laundry. Two features matter: a removable, zippered cover so you never soak the fill, and refillable fill so you can restore loft instead of replacing the whole bed. Not every donut has both, and it's worth knowing before you buy.
Refillable, washable-cover donut
FurHaven Calming Cuddler (36" and up). Removable zippered faux fur cover plus a fill you can top up when it flattens, which is the combination that ages best through repeated washes.
The category benchmark
Best Friends by Sheri (36"). Machine washable, with cover-only laundering on the larger sizes. The shag does mat over time, so the re-fluff routine above matters most on this one.
Both are fiber-fill donuts, so both benefit from the same low-heat, dryer-ball drying.

Frequently asked
What dryer settings should I use for a dog bed?
Low or no heat (air-fluff / delicate), with two or three wool dryer balls, for about 20–30 minutes. High heat is the main thing that permanently damages synthetic fur, so keep it off.
My rim is still lumpy after drying — now what?
Knead the clumps apart through the fabric, run another short low-heat cycle with the balls, and shape the rim by hand while it's still slightly damp. It usually takes one or two rounds.
Can I just air-dry it instead of using the dryer?
For faux fur, no. Air-drying alone leaves it stiff and matted because nothing separates the fibers. If your care label says air-dry only, dry it flat and brush the pile out with a slicker as it dries.
Is losing fluffiness after washing a defect?
Not usually. Some loft loss per wash is normal wear. Re-fluffing recovers most of it; when it stops recovering, top up refillable fill or replace a sealed bed.
