Walk into any pet store or browse online and you'll find two dominant dog bed styles competing for your attention: memory foam beds and bolstered beds. Both claim to offer superior comfort and support — but they serve different dogs in different ways. This guide breaks down the real differences so you can make the right call for your pup.
For a full overview of our bed collections, visit our Orthopedic Dog Beds Guide.
What Is a Memory Foam Dog Bed?
Memory foam is a viscoelastic material that responds to heat and pressure, conforming to the shape of your dog's body. Originally developed by NASA for aircraft cushioning, it's now widely used in human and pet bedding for its pressure-relieving properties.
How it works: When your dog lies down, the foam slowly compresses and molds to their body contours, distributing weight evenly across the surface. This reduces pressure points — the concentrated areas of pressure that cause discomfort during long periods of rest.
Best for:
- Senior dogs with arthritis or joint pain
- Dogs recovering from surgery or injury
- Dogs with pressure sore sensitivity
- Large and giant breeds with significant body weight
- Dogs that sleep in one position for extended periods
Considerations:
- Can retain heat — may be less comfortable for dogs that run warm
- Higher quality memory foam is significantly more durable than cheap alternatives
- Heavier and less portable than bolstered beds
- Covers must be removable and washable for hygiene
What Is a Bolstered Dog Bed?
A bolstered dog bed features raised edges — a padded border that surrounds some or all sides of the sleeping surface. The bolster serves as a built-in headrest, backrest, and sense of enclosure that many dogs find deeply comforting.
According to the American Kennel Club, dogs that curl up to sleep or like to rest their head on a raised surface tend to strongly prefer bolstered beds — the raised edges mimic the feeling of being nestled against something solid, which is instinctively calming for many dogs.
Best for:
- Dogs that curl into a ball when sleeping
- Dogs that like to rest their head or back against something
- Anxious dogs that benefit from a sense of enclosure
- Dogs of any age or size
- Dogs that need both comfort and a defined sleeping space
Considerations:
- The bolster fill quality varies widely — cheap bolsters flatten quickly
- Not ideal for dogs that sprawl completely flat
- Senior dogs with mobility issues may find it harder to step over high bolsters
Key Differences at a Glance
- Support type: Memory foam distributes pressure evenly across the body; bolsters provide lateral support and a sense of enclosure
- Sleep style fit: Memory foam suits sprawlers and side sleepers; bolsters suit curlers and leaners
- Temperature: Memory foam retains more heat; bolstered beds with plush fill tend to sleep cooler
- Mobility: Low-profile memory foam beds are easier for senior dogs to get in and out of; high bolsters can be a barrier for dogs with limited mobility
- Durability: High-density memory foam outlasts cheap polyester fill; ballistic nylon covers (like our Armor™ line) dramatically extend the life of any bed
Can You Get Both? Yes — Bolstered Orthopedic Beds
The good news: you don't have to choose. The best orthopedic dog beds combine supportive fill with bolstered edges — giving your dog the pressure relief of orthopedic support and the comfort of raised sides in one bed.
Our bolstered orthopedic beds do exactly this:
- Round Bolstered Furvana™ — plush orthopedic fill with full bolster surround; ideal for curlers
- Round Bolstered Armor™ — ballistic nylon exterior, orthopedic fill, full bolster; built for tough dogs. See our full review: Best USA-Made Round Bolstered Dog Bed.
- Furvana™ Cloud Rectangle Bolstered — plush orthopedic fill in a rectangle shape with bolster edges; ideal for sprawlers who also like to lean
Which Should You Choose?
Choose a memory foam or orthopedic fill bed if your dog:
- Has arthritis, hip dysplasia, or joint pain
- Is a senior dog (7+ years for large breeds) — see our Best Orthopedic Dog Beds for Senior Dogs guide
- Is recovering from surgery
- Sprawls completely flat when sleeping
- Is a large or giant breed — see our Best Dog Beds for Large Breeds guide
Choose a bolstered bed if your dog:
- Curls into a ball when sleeping
- Likes to rest their head or back against something
- Is anxious or benefits from a sense of security
- Is any age or size
Choose a bolstered orthopedic bed if your dog:
- Needs joint support AND likes to curl or lean
- Is a senior dog that also curls up
- You want the best of both worlds

A Note on Durability: Cover Material Matters
The fill inside a dog bed determines comfort; the cover determines how long the bed lasts. The ASPCA recommends washing dog bedding weekly — which means the cover needs to hold up to frequent laundering without pilling, shrinking, or losing its shape.
Our Armor™ line uses 1680D ballistic nylon — the same military-grade fabric used in body armor — for dogs that are hard on their beds. Our Furvana™ line uses premium plush fabric for dogs that prioritize softness. Both are designed to be washed regularly without degrading. For signs that any bed has reached the end of its life, see our guide: When Should You Replace Your Dog's Bed?
Frequently Asked Questions
Is memory foam or bolstered better for a dog with arthritis?
For dogs with arthritis, a bolstered orthopedic bed is the ideal choice — the orthopedic fill relieves joint pressure while the bolster provides support for getting comfortable. If your dog has significant mobility limitations, choose a low-profile bolster they can step over easily. Our Round Bolstered Furvana™ is a popular choice for arthritic dogs.
Do bolstered beds flatten over time?
Cheap bolsters filled with polyester batting will flatten within months. Quality bolstered beds use denser fill that maintains its shape over years of use. Inspect the bolster periodically — if it's lost significant volume, it's time to replace the bed. See our full replacement guide: When Should You Replace Your Dog's Bed?
Are bolstered beds good for large dogs?
Yes — as long as the bed is sized appropriately. Large dogs need a bolstered bed large enough to fully stretch out inside the bolster border. Our Round Bolstered Armor™ is available in sizes to accommodate large breeds. For more on large breed bed selection, see our Best Dog Beds for Large Breeds guide.
What's the most durable dog bed cover material?
1680D ballistic nylon is the most durable cover material available for dog beds — it's the same fabric used in military-grade gear and body armor. Our Armor™ bed line uses this material for dogs that chew, scratch, or are simply hard on their beds.
