Top 5 Picks
#1
Best Overall
Moots Supreme Filling Formula, 8 lb (2 Cushions, 4 lb/Each), Refill for Pet Beds, Cushions and Pillows, Large
We chose this because the 8 lb divided fill (4 lb per cushion) offers a customizable level of plushness for two separate bed compartments. The Supreme Filling Formula uses a premium blend that resists clumping, and the bag allows easy redistribution. It works well for large crates or as bolster refill.
#2
Best Orthopedic
KSIIA Orthopedic Dog Bed Dog Crate Bed Waterproof for Large Dogs Deluxe Plush Washable Pet Mat with Egg Crate Foam & Removable Cover, 35 x 22 Inch, Gray
We picked this for its waterproof layer combined with plush orthopedic support in a low-profile design. The deluxe cover is easy to remove and wash, and the 4-inch foam core provides pressure relief. Ideal for large breeds needing moisture protection.
#3
Best Budget
Dog Bed Stuffing Liner Replacement with Inter Layer Not Waterproof 36 x 24 Inch
We selected this for its affordable price point and the inter-layer construction that keeps stuffing evenly distributed. It's sized 36 x 24 inches, fitting many standard crate beds. While not waterproof, it works well for dry environments and casual use.
#4
Best Premium
JOYELF Orthopedic Memory Foam Dog Bed Replacement Filling Bolster Insert Stuffing Pillow - XX-Large Size
We chose this because the dense orthopedic memory foam retains its shape well over time and comes in a convenient replacement fill for bolster beds. The product name specifies 'replacement filling' and it fits many existing covers. Ideal for owners who want high-density support.
#5
Runner-Up
Waterproof Dog Bed Liner, Washable Replacement Cover Reusable Pet Pee Water Resistant Proof with Zipper, Liner Only 36x27 inch
We included this for its practical waterproof liner that turns any bed into a washable, leak-resistant setup. The reusable design reduces waste, and it's easy to clean. Best for owners with incontinent dogs or puppies in training.
Before You Buy
Key Buying Factors
01
Fill Material & Density
Memory foam offers orthopedic support but adds weight; polyester fiber is lighter and cheaper but may compress faster. Choose based on your dog's age and joint health.
02
Waterproof Protection
For senior dogs or puppies, waterproof liners prevent accidents from soaking the bed. Removable covers are easier to clean than one-piece inserts.
03
Cover Material & Washability
Machine-washable covers simplify maintenance. Look for zippers that are sturdy enough for repeated cycles. Some inserts are only spot-clean.
04
Size & Shape Fit
Measure your dog's crate or bed interior before buying. Inserts often run a few inches smaller than listed; check the exact dimensions in the product description.
05
Longevity & Clumping Resistance
Fiber fills can shift and clump over time. We prefer bonded or inter-layer designs that keep the stuffing evenly distributed. Foam cores maintain shape longer.
06
Allergen & Odor Management
Hypoallergenic fills reduce sneezing, while odor-resistant fabrics help between washes. Some materials off-gas initially-look for low-VOC certifications if sensitive.
Living With It
Care, Cost and Maintenance
Regular Fluffing & Rotation
Rotate the insert weekly to prevent uneven wear. Fluff fiber fill by shaking or beating lightly with hands to redistribute clumps.
Spot Cleaning vs Machine Wash
Always follow the product label. Most foam inserts are spot-clean only; fiber inserts with removable covers can be machine washed on gentle cycle and air dried.
Sun-Drying & Deodorizing
Sunlight helps kill bacteria and neutralize odors. For waterproof liners, avoid high heat which can degrade the coating.
Pro tip
When replacing an insert, measure your existing bed cover's interior dimensions (not the outer size), and subtract 1-2 inches to ensure a snug fit without bulging the seams.
Frequently asked questions
How often should I replace the pillow insert?
Typically every 1-2 years, depending on fill quality and how much your dog uses the bed. If the insert develops permanent lumps or becomes thin in the center, it's time for a new one.
Can I wash any insert in the washing machine?
Only if the label says machine washable. Fiber fill inserts with removable covers can be washed, but foam inserts should be spot cleaned only. Always air dry.
What size insert do I need for a 36-inch crate?
Most 36-inch crates fit a 32-34 inch long bed. For inserts, look for specified dimensions like '36 x 24 inches' but measure the actual interior space.
Is memory foam safe for all dogs?
Yes, memory foam is generally safe. However, some dogs may try to chew it, so supervise heavy chewers. Choose CertiPUR-US certified foam for lower off-gassing.
How do I stop the fill from clumping?
Look for inserts with inter-layer stitching or baffle boxes that keep fill in place. For fiber inserts, fluff them regularly and avoid over-washing.
