The short answer: choose Premium Fiberfill for a plush bed whose firmness you can adjust, 4″ Memory Foam for even, pressure-relieving support (a popular choice for senior dogs), and High-Density Foam for the firmest, longest-lasting support, made for large and giant breeds or a cushion people will sit on too. On cushion beds the fill also sets the height of the band: 4″ for fiberfill and 5″ high-density foam, 3″ for 4″ memory foam and 4″ high-density foam.
The fabric is what you see; the fill is what your dog feels every night. Every J’adore bed is made to order, so you pick the fill when you design your bed. This guide explains each fill we use, how they compare, which beds offer them and how to choose for your dog.
The Fills at a Glance

Which Beds Offer Which Fill
| Bed | Fills you can choose |
|---|---|
| Rectangle and Square | Premium Fiberfill, 4″ Memory Foam, 4″ High-Density Foam, 5″ High-Density Foam, Cover Only |
| Round and Cave | Premium Fiberfill, 4″ Memory Foam, Cover Only |
| Cuddle, Edgy and Throne | Premium Fiberfill seat or Memory Foam seat, Cover Only |
| Cozy Cuddle | Premium Fiberfill, Memory Foam seat, Sustainable Fill, Cover Only |
| Penthouse and Pillow | Premium Fiberfill, Cover Only |
On bolster beds the fill you choose goes in the seat. On the Cuddle and Cozy Cuddle beds, the smaller sizes (XXS through Small on the Cuddle) use shredded memory foam and the larger sizes use a 4″ thick piece. The Throne bed’s sides are always made with high-density foam, whichever seat you pick.
Premium Fiberfill: Plush and Adjustable
Our fiberfill is a premium down-alternative clusterfill. Cluster fibers stay springy instead of clumping or going flat the way standard fill does, and it’s rated to last three times longer. We stuff our beds on the firmer side so they’re supportive from day one. If your dog likes it softer, unzip the insert and take some fill out until it feels right. Sewn channels inside the insert keep the fill evenly spread over time.
Fiberfill suits dogs who like to nest, dig and sink in, and anyone who wants to fine-tune the firmness themselves. It’s offered on every bed.
Memory Foam: Even, Pressure-Relieving Support
We use a high-quality 4 lb density memory foam, 4″ thick. It’s designed to relieve pressure points by spreading your dog’s weight evenly, which is why it’s a popular choice for senior dogs. Its typical life is 10+ years, and it’s CertiPUR-US® certified. On cushion beds a memory foam insert gives the cover a 3″ band.
High-Density Foam: The Firmest Support
High-density polyurethane foam (2.8 density, 35 compression) gives firm, long-lasting support, with a layer of batting on the top and bottom for comfort. Its typical life is 12+ years, and it’s CertiPUR-US® certified. It comes in two thicknesses on the Rectangle and Square beds:
- 4″ High-Density Foam (3″ band): firm support for large dogs, and the one to choose for a bench, window seat or cabinet cushion.
- 5″ High-Density Foam (4″ band): our thickest, for giant breeds that need maximum support and dogs that like a firm bed.
If both your dogs and your people will use the cushion, such as a window seat or bench, choose high-density foam. For a custom-size cushion we use 4″ or 5″ foam depending on the overall size; if you need a specific thickness, just let us know.
Sustainable Fill
On the Cozy Cuddle, you can choose Sustainable Fill: a premium recycled fiberfill made from post-consumer plastic bottles. It’s heavy-weight and supportive, stuffed on the firmer side and adjustable like our Premium Fiberfill, with channels and a zipper to keep it in place.

| Best for | Nesters, diggers, dogs who like to sink in | Senior dogs; dogs who like a supportive surface | Large and giant breeds, firm-bed lovers, benches and window seats |
| Firmness you can adjust | Yes, by removing fill | No | No (choose 4″ or 5″) |
| Typical life | Not stated | 10+ years | 12+ years |
Orthopedic vs Memory Foam: What’s the Difference?
“Orthopedic” isn’t a separate material. It describes a bed built to support the body evenly rather than letting it sink to the floor. On our beds, both foams are supportive: memory foam relieves pressure points by spreading weight evenly, and high-density foam is firmer and holds its shape longest. So the real choice is how firm your dog likes their bed and how much they weigh.
For a deeper look at choosing support for an older dog, read our guide to custom orthopedic dog beds for senior dogs, and for the soft-versus-supportive question, orthopedic vs. plush dog beds.
Are Orthopedic Dog Beds Worth It?
A foam bed costs more than fiberfill, but it’s built to keep its support for years: 10+ for our memory foam and 12+ for high-density foam. It’s worth it if your dog is a large or giant breed, likes a firm surface, or is a senior who settles better on even support. If your dog loves to nest and burrow, a plush fiberfill bed may suit them better, and you can still adjust it. If your dog has a health condition, ask your vet which kind of support they recommend.
How the Fill Sets the Band Height
On cushion beds, the band is the side wall of the cover, and it’s sized to fit the insert:
- Premium Fiberfill: 4″ band.
- 4″ Memory Foam: 3″ band.
- 4″ High-Density Foam: 3″ band.
- 5″ High-Density Foam: 4″ band.
Buying Cover Only on the Rectangle, Square, Round or Cave bed? Choose the band height yourself, from 2″ to 8″ (4″ is selected to start). If you’re replacing a J’adore cover, check your past order for the fill you chose, or contact us and we’ll tell you the height you need. A replacement cover for a J’adore bed is matched to the style and size you ordered.
Protecting the Fill
A waterproof insert cover, an add-on when you design your bed, sits over the insert under the outer cover and keeps accidents and spills out of the fill. On bolster beds you can protect the seat alone or the seat and the bolsters. Foam inserts can’t go in the washing machine, so protecting them pays off; our dog bed care guide explains how to clean every part of the bed.
If an insert does wear out, you don’t need a new bed: order a replacement insert.
Choosing the Fabric
The fill is half the decision. For the outside of the bed, our guide to durable, washable cover fabrics compares our fabrics on durability, pet hair and washing. And to get the size right before you choose either, start with the dog bed size guide.
