Best Friends by Sheri Calming Donut Review: The Curl-Up Bed for Dogs Who Nest

The Best Friends by Sheri Original Calming Donut sits at number six on our Best Dog Beds list with an 8.2, built for one specific kind of dog: the one that sleeps curled in a tight circle rather than stretched out flat. Buy it for that dog and you'll get a genuinely cozy, easy-to-wash nest that two independent reviewers both liked. Buy it expecting orthopedic joint support, and you'll be disappointed — that's not the job this bed is built for.

What it is

The Calming Donut is a deep-dish nest: a raised rim wraps around a shag faux-fur interior filled with polyfill, giving a curled-up dog something to rest its head and spine against on every side. It is explicitly not a memory-foam orthopedic design — the entire construction is built around the bolster effect of the rim, not a supportive mattress underneath.

Sizing runs on a weight chart rather than a single one-size product: a 23-inch Small tops out around 25 pounds, a 30-inch Medium (the version listed on Amazon) goes up to 45 pounds, and larger 36-, 45-, and 54-inch versions scale up for bigger dogs. The Small washes as a complete unit; Medium and larger sizes have a removable, machine-washable cover. Street price on the 30-inch Medium runs in the $40 to $70 range depending on color and retailer — Gavler lists it at $50.

In use and performance

Two independent reviewers who actually put dogs on this bed arrived at similar conclusions, and their praise and their criticism both matter here. Apartment Therapy's Riva Syrop leaned hard into the comfort factor: "The bed is donut-shaped, which creates the perfect cocoon-like sleeping environment, and it's so soft and cozy that I occasionally have to pull my teenager off of it." That's a genuinely useful signal — a bed comfortable enough to poach human interest is doing something right on softness and shape.

PetsRadar's Kathryn Williams focused more on the mechanics of how the faux fur actually behaves against a dog's body: "The faux fur warms on contact with your dog's body, mimicking the soothing feel of a mother's coat and promoting better sleep." That's a specific, testable claim about the material rather than a vague comfort platitude, and it points at why this style of bed is marketed toward anxious or nervous dogs specifically — the warming, enclosing effect is the actual mechanism, not just branding.

On the practical side, Apartment Therapy's washability test is about as real-world as testing gets: "The bed is also easily machine washable — even in the tiny washer/dryers of my NYC apartment basement — and comes out clean and soft every time." For a bed that's going to collect dog hair and the occasional accident, that's not a minor feature.

The honest limitation both reviews converge on is support. PetsRadar's verdict is blunt and specific: "Not very supportive in the middle." That's the trade-off of a polyfill-and-rim design instead of a foam mattress — comfortable for curling, but without the structural support a foam bed provides for a dog lying flat or dealing with joint pain.

Strengths

• Genuine cocoon comfort. Independent reviewers at both Apartment Therapy and PetsRadar praise the curl-up shape and soft shag fur, not just the marketing copy around them.
• A believable calming mechanism. The faux fur's warming effect against a dog's body is a specific, observed detail from PetsRadar's testing, not just a "calming" label slapped on a generic bed.
• Actually washable in a normal machine. Confirmed in a small NYC apartment washer/dryer — a realistic test most owners will recognize.
• Sized for a wide range of dogs. Five sizes from 23 inches up to 54 inches means this isn't limited to small breeds.

The trade-offs — who should skip it

• Weak center support. PetsRadar's own assessment — "not very supportive in the middle" — means this is the wrong bed if your dog has hip dysplasia, arthritis, or another condition where a supportive orthopedic mattress matters more than a cozy curl-up shape.
• Not built for dogs that sprawl flat. The rim and nest shape are wasted on a dog that stretches out rather than curls; an open rectangle bed will suit that dog better.
• Size matters more than usual here. Because the whole design depends on the rim fitting the dog's curled shape, sizing a large dog into too small a donut defeats the purpose. Check the weight chart, not just the dimensions.
• Shag fur means real upkeep. It holds hair effectively, which is good for warmth but means more frequent washing for owners of heavy shedders.

How it compares

Within Gavler's Best Dog Beds list, the Calming Donut occupies a different lane than the ranking's orthopedic specialists. The K9 Ballistics Tough Ripstop Rectangle at rank three is the pick for a dog that sprawls flat and needs a durable, dig-resistant shell rather than a nest — the two beds solve genuinely different problems rather than competing head-to-head. For owners who want the donut's curl-up shape but with real orthopedic support underneath, the PetFusion Ultimate Dog Bed at rank two is the closer match on the support axis, trading some of the shag-fur coziness for a proper foam base.

The Gavler verdict

An 8.2 for a bed that does exactly what it promises: a warm, enclosing nest for a dog that curls up to sleep, backed by two independent reviewers who both liked the comfort and the washability. It is not, and doesn't claim to be, an orthopedic mattress — PetsRadar's own testing found the center support weak, so a dog with joint issues should look elsewhere. Buy it for the anxious curler who wants to disappear into a soft, warm circle at night; size it by weight, not by guesswork, and it'll earn its spot on the floor.

Common Questions

Is the Best Friends by Sheri Calming Donut worth it in 2026?

Yes, for a dog that sleeps curled in a circle rather than sprawled flat. It ranks sixth on Gavler's Best Dog Beds list with an 8.2, and reviewers at Apartment Therapy and PetsRadar both praise the cocoon-like comfort and easy washability. It is not an orthopedic mattress, though — if joint support is the priority, look at a dedicated foam bed instead.

Does the Best Friends by Sheri Calming Donut provide orthopedic support?

No. It's built around polyfill and a raised rim, not memory foam, and PetsRadar's own review flags that it is 'not very supportive in the middle.' For hip or joint issues, a dedicated orthopedic bed like PetFusion or Big Barker is the better choice; the donut's job is comfort and anxiety-easing curl-up space, not medical-grade support.

How do I size the Best Friends by Sheri Calming Donut correctly?

By weight, not by eye. Sheri's own bands run from a 23-inch small (up to 25 lb) through a 30-inch medium (up to 45 lb) and larger sizes for bigger dogs. A dog sized into too small a donut won't get the cocoon effect the bed is designed around, so check the weight chart before buying.
