Think of pet bed accessories as the finishing touches that turn a simple mat into a cozy, supportive retreat. Whether your dog naps like a champ or your cat curls up like a tiny loaf, the right accessories protect your furniture, extend the life of a bed, and give your animal companion better rest. Plus, a well-chosen accessory solves common problems—stains, odor, joint pain—without breaking the bank.
If you’re hunting for the right pieces, start with the basics: covers, inserts, bolsters, and pads. Each plays a different role, and mixing them creates a tailored sleep system for your pet. Below I break down the most popular options and why they matter.
Waterproof covers protect mattress foam from accidents and spills, which is especially useful for puppies, senior pets, and messy eaters. Look for covers made from breathable polyester with a waterproof backing—these keep fluids from seeping through while allowing some airflow. Sizes often run 18" to 48" across, so measure your existing bed before buying.
Orthopedic memory foam inserts provide pressure relief for joints and hips. If your pet is over 7 years old or has arthritis, an 3" to 4" thick memory foam base can make a world of difference. These inserts often come with removable covers for easy washing, and higher-density foam holds shape longer.
Bolstered beds have raised sides that provide a sense of security and a place to rest the head. Cats and many small dogs love these. Bolsters come in various heights—usually 3" to 6" tall—so pick a height that suits your pet’s size and mobility.
For hot summers, cooling gel mats or breathable mesh surfaces help prevent overheating. Conversely, heated pads with low-wattage settings offer gentle warmth during cold months or for pets with poor circulation. Always pick pads with chew-resistant cords or automatic shut-off features for safety.
The fabric and fill impact durability, washability, and comfort. Common fabrics include microfiber, cotton blends, faux fur, and waterproof polyester. Fill options range from shredded memory foam to polyester fiberfill and bolstered foam. For allergy-prone pets, hypoallergenic covers and foam options reduce irritants.
Tough materials like ballistic nylon or canvas resist claws and rough play, but they’re not as soft as faux fur or plush microfleece. A layered approach works well—use a rugged waterproof cover under a soft, removable top layer so your pet gets comfort and you get protection.
Picking the right size is crucial. Measure your pet from nose to tail and add the length they like to stretch out—most dogs need beds between 24" and 42" depending on breed and sleeping style. Cats commonly fit beds 16" to 24". If your dog likes to sprawl, go up one size from their body length; if they curl, choose a circular bed with a diameter of 18" to 36".
Small breeds: 18"–22" beds; Medium breeds: 24"–30"; Large breeds: 36"–42"; Extra-large breeds: 48" and up. These ranges will help you match an accessory—like a bolster or cover—to your existing pet bed without guessing.
Finding the right accessory often comes down to selection, price, and convenience. Here’s a breakdown of reputable US retailers with strong pet bedding sections so you can shop confidently.
Chewy is a favorite for pet owners who want a wide selection of brands that focus exclusively on pets. You’ll find orthopedic mattresses, waterproof covers, and heated pads with user reviews that help you decide. Chewy excels at subscription options for recurring purchases like replacement covers and pads.
PetSmart offers in-store and online options with a broad mix of budget and premium lines. They carry their own house brands and well-known manufacturers, so you can test materials in person and pick up accessories quickly if you need them that day.
Petco blends practical options with higher-end specialty beds. Their stores typically stock several orthopedic and bolstered designs and often run promotions, making them a good spot to score quality items without paying top dollar.
Amazon delivers sheer variety and fast shipping. You’ll find everything from cooling mats to plush memory foam beds, and the review system gives real-world feedback on durability and sizing. Watch for trusted sellers and check return windows before purchasing.
Both carry affordable, mainstream pet bed accessories that suit casual pet owners. Walmart range covers low-cost waterproof liners and cushions, while Target has stylish, decor-friendly designs that fit modern homes. Both are great when you want a budget-friendly upgrade.
Wayfair emphasizes home-style pet beds that blend with your décor; their options often include designer fabrics and larger sizes. Bed Bath & Beyond has convenient accessories like washable covers and specialty pillows—handy if you want functional pieces that also look nice on a shelf.
When you compare products, focus on a few key attributes: washability, waterproofing, warranty, and material safety. A machine-washable cover saves time. A waterproof liner protects the foam. A manufacturer warranty hints at quality. And third-party testing or certifications can indicate safer materials.
How often will you wash the bed? If weekly or biweekly, make sure both the cover and insert are machine-friendly. Zippers and removability are small features that make a big difference in real life—look for covers that unzip fully for easy laundering.
If you’re on a budget, you can still get reliable accessories: polyester waterproof covers and fiberfill pads are inexpensive and useful. Premium options—like high-density memory foam, removable plush toppers, and designer covers—offer extra comfort and longevity. Choose based on your pet’s needs: heavy chewers and anxious dogs may need rugged, cheaper layers you can replace more often.
Splurge on orthopedic memory foam or a heated pad if your pet has medical needs—arthritis, hip dysplasia, or chronic joint pain. These items often relieve discomfort and can reduce vet visits in the long run, making them cost-effective for senior pets.
Dogs and cats have different sleep habits. Dogs often like sprawling surfaces or bolsters they can lean into, whereas cats prefer enclosed or elevated spots. Think about personality: anxious dogs may love a fortified bolster bed, while adventurous cats might prefer a window perch or a removable soft pad that travels easily.
Puppies and kittens can be destructive—chew-resistant fabrics and antimicrobial surfaces help. Choose washable, replaceable covers, and avoid heating pads without a chew-proof design. Smaller beds (18"–22") suit most young pets until they grow, so buying a modest-sized accessory first is sensible.
Keeping accessories in top shape is easier than you think. Rotate and air out foam inserts, spot-clean stains quickly, and machine wash removable covers on a gentle cycle. For deep odors, a light baking soda treatment before washing freshens fabrics without harsh chemicals.
Replace foam inserts every 2–4 years, depending on use; elastic or fiberfill toppers might need replacing sooner. If the foam is lumpy, compressed, or failing to rebound, it’s time for a new insert. Regular inspection keeps your pet sleeping safely and comfortably.
For trips to the cabin, car rides, or weekend visits, choose a foldable mat or inflatable pet bed. These often pack into a small bag and fit under car seats. Try a travel bed with a removable, washable cover for quick cleanup after sandy beaches or muddy hikes.
Vehicle-specific accessories—like crash-tested car seats for small dogs or non-slip travel mats—help keep pets comfortable and safe. Non-slip bottoms around 0.2" thick provide traction on leather seats without adding bulk.
Don’t want to buy new? Upcycle an old mattress by adding a waterproof cover and a plush topper, or sew a zippered cover from durable fabric. DIY projects let you customize size and fabric—perfect if your pet has unusual dimensions or you’re trying to match home décor.
Measure your pet, choose foam density (3" memory foam is a good start), wrap the foam in batting for softness, and sew a removable cover with a zipper. Use machine-washable fabrics to keep the project practical and low-maintenance.
Before you buy, compare product specs and user reviews across multiple sources. Specialty pet retailers, general marketplaces, and comparison sites all add value: retailers show inventory, marketplaces show variety and fast shipping, and comparison sites compile features and prices in one place—handy for finding the best match quickly.
Before clicking “add to cart,” run through this quick checklist: correct size in inches, washable cover, waterproof liner if needed, appropriate foam density, chew-resistant materials for young pets, and clear warranty or return terms. This small ritual prevents buyer’s remorse and ensures your pet gets lasting comfort.
Choosing the right pet bed accessories isn’t just about style—it's about improving sleep, protecting investment, and enhancing your pet’s health. From waterproof covers and orthopedic foam to travel mats and cozy bolsters, there’s a smart solution for every pet and budget. Use the size guidelines, prioritize washability, and shop trusted US retailers like Chewy, PetSmart, Petco, Amazon, Walmart, Target, Wayfair, and Bed Bath & Beyond to find the best fit. With a few thoughtful upgrades, you’ll give your furry friend a nest they truly deserve.
