There's a universal truth every cat parent learns, usually the hard way: No matter what you buy for your cat, they will immediately want to claim more space for their own.
You spend 20 minutes assembling a cat tree. They sleep on the box. You buy a perfectly proportioned cat bed. They hang off three sides of it. You adopt a second cat specifically to give the first one company. They both claim the same 12-inch corner of the couch.
Cats don't just want comfort. They want room for comfort.
That's the insight behind Knead's expanded size lineup. Both the Therapeutic Bed and the Orthopedic Bed now come in two sizes: the original 20" Small and the new 25" Large—a 5-inch difference that, as it turns out, changes everything for large breeds, side sleepers, and cats who have decided that sharing is, actually, caring.
Here's how to figure out which of the four is right for the cats in your home.
Start Here: Know Your Cat's Sleep Style
Before size, there's sleep style. Cats don't all sleep the same way, and the shape of how your cat rests matters almost as much as their weight when it comes to choosing the right fit.
The Curler: Nose tucked to tail, paws folded under, a perfect circle. This is the classic cat position, and it's practical: Curling conserves body heat and makes the cat feel enclosed and secure. Curlers can often fit comfortably in a smaller footprint, but they still appreciate a bed with enough diameter that they're not pressed against the edges.
The Loafer: Paws tucked beneath the chest, alert but relaxed. A compact, confident position that works well in both sizes, but becomes especially comfortable with the deeper 5.5" foam of the 25" Large, which lets even a substantial cat sink in slightly without bottoming out.
The Side Sleeper / Sprawler: Fully extended—legs out, belly exposed, sometimes comically horizontal. This is the position of a cat that trusts its environment completely. It's also the position that makes undersized beds instantly obvious. Side sleepers need room. The 25" gives them plenty.
The Overlap: Two cats who've decided that one bed is better with company. More on them in a moment.
The 20" Small: The Right Fit for Most Cats
Diameter: 20" | Foam depth: 4"
The original Knead size was designed for the statistical center of domestic cat ownership: single cats, standard-sized breeds, cats who curl or loaf, and cats on the smaller end of the side-sleeping spectrum.
If your cat weighs under 14 lbs. and doesn't have strong sprawling tendencies, the 20" is likely the right call. The 4" memory foam depth is substantial—meaningfully deeper than almost any competitor in this category—and the ergonomic contour guides natural spinal alignment whether your cat is curled tight or loosely settled.
This is also the right size for:
-
Kittens establishing their sleep routine early (orthopedic support from day one is never too soon)
-
Slender adult cats regardless of length
-
Cats who prefer a snugger, more enclosed feeling (some cats find a tightly fitting bed more calming than a more open surface)
-
Homes where multiple beds will be placed in different rooms, making the 20" a practical per-room solution
One verified Knead buyer put it well: "My seven-year-old cat Lucky has never been interested in any bed until now! He sleeps comfortably curled up on his Knead Orthopedic Bed." Lucky, apparently, is a curler.
The 25" Large: Built for Cats Who Knead More Room
Diameter: 25" | Foam depth: 5.5"
This is the size Knead launched earlier this year, and it was built around a simple observation: Some cats—and some households—were outgrowing the 20".
The 25" is 5 additional inches of diameter and 1.5 additional inches of foam depth. That's not incremental. For a 15-pound Maine Coon who sleeps fully extended, or two bonded cats who refuse to nap apart, it's the difference between "technically fits" and "genuinely comfortable."
The deeper 5.5" foam of the Large Beds is particularly worth noting. Heavier cats need more foam to prevent what engineers call "bottoming out"—the point where body weight compresses the foam all the way through to the rigid base beneath. At 5.5", the Large Beds maintain their pressure-distributing, joint-protecting properties under significantly more weight than the standard size, ensuring the therapeutic or orthopedic benefits don't disappear the moment a large cat settles in.
Large Breeds: When Standard Sizing Simply Doesn't Cut It
If you share your home with one of the big-bodied breeds, you already know that "one size fits most" has never applied to your cat. Here's what you're actually working with:
Maine Coons are the gentle giants of the domestic cat world. Male Maine Coons commonly weigh 18–21 pounds, with some individuals reaching 25 lbs. and body lengths of up to 40 inches nose to tail. A 20" bed for a fully grown male Maine Coon is like a king-size human sleeping on a twin-size bed. The 25" Large is the appropriate choice, without question.
Ragdolls are deceptively large — their silky fur and floppy demeanor make them look lighter than they are. Ragdolls are also famously relaxed when picked up, which translates to sprawling, fully-extended sleeping postures. Their instinct isn't to curl—it's to expand. A 25" Orthopedic or Therapeutic Bed meets that instinct with the space it requires.
Siberians are a medium-to-large breed with a substantial, muscular build. A Siberian cat's average size is between 8 and 18 pounds, with males typically weighing slightly more than females. Siberians are also known for being highly social and affectionate, which makes them prime candidates for the 25" in multi-cat households. They'll want to share the space, and they'll appreciate the room to do it.
Norwegian Forest Cats (Wegies, to their fans) are Scandinavia's answer to the Maine Coon—large, thick-coated, and built for cold climates they'll never actually see in a domestic setting. Mature females usually weigh 9 to 12 pounds while males regularly tip the scales at 16 pounds or more. For Norwegian Forest Cats, the Knead 25" Large isn't a luxury—it's a realistic fit.
Chausies, Turkish Vans, Bengals over 14 lbs. If your cat is consistently over 14 lbs. regardless of breed, the Large is the right foundation for their sleep system.
One Knead customer reviewing the 25" Large Orthopedic Bed summarized it simply: "I was looking for a big cat bed for my large girl, and this one is made of nice memory foam in a shape that is great for cats." Her large-breed cat, notably, chose the bed over every other surface in the room.
Two Cats, One Bed: The Case for the 25" in Multi-Cat Homes
Here's something that surprised a lot of early adopters of the 25": They didn't buy it for a large cat. They bought it because their cats—standard-sized, normal-weight, perfectly typical cats—kept trying to share the 20".
This is entirely consistent with feline behavior science. One of the most common signs of a bonded pair is two cats sleeping together. Cats are instinctively cautious about where they rest, so sharing that vulnerable time with another cat shows complete trust. Bonded cats don't just tolerate each other's presence during sleep—they actively seek it out. There are numerous advantages for bonded cats who share sleeping spaces: warmth, a sense of security, and the comfort that comes from the rhythmic purring and presence of a companion, helping cats to relax and sleep more soundly.
When your bonded pair decides that one Knead bed is their preferred shared territory, fighting it is futile. The 25" gives them the space to do it properly—enough room for two cats to settle without one of them hanging off the edge, and enough foam depth to distribute the combined weight without compromising the orthopedic support either one of them is sleeping on.
A Knead customer with a multi-cat household captured this dynamic perfectly in her review of the Therapeutic Bed: "I have five cats, but three Knead beds. I have seen Joey, my youngest all-black cat, come over to the bed and squeeze himself onto the bed while Eddie is laying there. Eddie, big orange tabby who is very vocal, will get angry, growling, and leaves. Then Joey has the bed to himself... I might have to buy two more Knead beds, but the larger sizes."
The 25" doesn't solve every cat's territorial logic. But it does give two cats the option to share gracefully, which, for bonded pairs, can become the preferred arrangement within days.
Another multi-cat parent, reviewing the Orthopedic Bed: "All six of my boys, ranging in age 11 to 2, loved this Knead bed. In the first day out of packaging, everyone had their turn in it." She went with the larger size. Wisely.
Choosing Your Style: Therapeutic or Orthopedic?
Size determines fit. Style determines function. Here's the short version:
The Knead Therapeutic Bed adds InfraTherm nano-heating to the orthopedic memory foam foundation, warming to a cat-safe 103–104°F, with optional heat-activated herbal therapy pads for additional anti-inflammatory support. Clinically proven to reduce arthritis pain in 82% of cats in a six-week Citruslabs study, it's built for senior and arthritic cats, cats in heavily air-conditioned environments, or cats who obsessively seek heat year-round.
Available in both Small (20") and Large (25") sizes. For large arthritic breeds—a senior Maine Coon, an aging Ragdoll — the 25" Therapeutic is the most complete care investment Knead offers.
The Knead Orthopedic Bed is our non-heated version—the same human-grade, slow-rebound memory foam and ergonomic contour, without the heating element. It's the proactive choice: orthopedic joint protection for cats at every life stage, before they need rescue. In a Citruslabs evaluation, 80% of participants showed improved sleep quality and 78% became more active overall.
Also available in both Small (20") and Large (25"). The Orthopedic is upgrade-ready: a compatible heating layer can be added later without replacing the bed your cat already knows and loves. This makes the 25" Orthopedic an especially smart entry point for large-breed owners who want to invest in the right foundation now, with the option to add heat as their cat ages.

Still Not Sure? Here's the One-Question Shortcut
If you can answer yes to any of these, choose the 25" Large:
-
Does your cat weigh more than 14 lbs.?
-
Is your cat a Maine Coon, Ragdoll, Siberian, Norwegian Forest Cat, or other large breed?
-
Do your cats currently share sleeping surfaces?
-
Does your cat sleep stretched out rather than curled?
-
Do you have more than two cats competing for one sleeping spot?
If none of those apply, the 20" Small is a well-matched, properly proportioned fit for your cat and your space.
Either way, the foam is the same quality. The ergonomics are the same science. The commitment to your cat's comfort is identical. The size just makes sure all of that actually gets to work.
Frequently Asked Questions
What size Knead bed does a Maine Coon need?
The 25" Large. Male Maine Coons commonly weigh 18–21 lbs. and can measure up to 40 inches nose to tail—the 20" Small isn't large enough to support their full body during rest. The 25" Large also has a 5.5" foam depth, which provides proper weight distribution for heavier cats and prevents the foam from compressing through to the base beneath.
Can two cats share one Knead bed?
Yes! And many bonded pairs actively choose to. Cats who sleep together are showing deep mutual trust, and a shared sleeping surface strengthens that bond. The 25" Large is the right size for two cats to share comfortably. Two standard-sized cats can share the Large without either one hanging off the edge. One larger cat and one smaller companion can also share comfortably.
What's the difference between the 20" and 25" Knead beds beyond diameter?
Beyond the 5" diameter increase, the 25" Large also has a 5.5" foam depth versus 4" in the Small. This additional foam depth is especially important for heavier cats—it ensures that body weight is properly absorbed and distributed without bottoming out, so the orthopedic and (in the Therapeutic version) heating benefits remain fully effective.
Is the 25" Large available in both the Therapeutic and Orthopedic styles?
Yes. All four combinations are available: Therapeutic Small (20"), Therapeutic Large (25"), Orthopedic Small (20"), and Orthopedic Large (25"). Both colors (white and black) are available in all four configurations.
What's the best Knead bed for a Ragdoll?
The 25" Large in either style. Ragdolls average 15–20 lbs. and are known for sprawling, fully-extended sleeping postures—simply put, they need room. For a younger adult Ragdoll, the Orthopedic Large offers proactive joint protection. For a senior Ragdoll showing arthritis symptoms, the Therapeutic Large provides clinically proven heat therapy alongside the orthopedic support.
Do cats prefer smaller or larger beds?
It depends on their sleep style and personality. Cats who curl tightly often feel more secure in a snugly fitted bed. Cats who sprawl or sleep on their sides need more surface area. Large breeds and bonded pairs almost always benefit from the 25" Large regardless of sleep style, simply because they need the room. When in doubt, size up—a cat can always choose to curl in a large bed, but can't uncurl in one that's too small.
Is the Knead Orthopedic Bed a good choice for large cats without arthritis?
Yes. Ergonomic orthopedic support and proactive joint protection aren’t just for cats with diagnosed joint conditions. They protect joints from cumulative wear over time, absorb the micro-impacts of daily jumping and activity, and promote deeper, more restorative sleep. For a large cat like a Maine Coon or Siberian, whose joints carry more weight with every landing, a high-quality orthopedic foundation from early adulthood is one of the most proactive things you can do for their long-term mobility.
