Mattress Beds for Dogs: Everyday Comfort with Room to Stretch

Some dogs love nothing more than stretching out for a deep, undisturbed nap. Whether they’re flopped on their side, belly-up, or splayed in every direction, dogs who sprawl need a bed that gives them space — and support.

That’s exactly where our mattress beds shine. Designed to mimic the comfort of a flat cushion or soft mat, they provide a stable surface with gentle resistance, helping dogs settle more quickly and stay comfortable for longer.

They’re especially loved by larger breeds, older dogs, and any pup who’s outgrown their squishy puppy bed. And because they work just as well in a crate, under a desk, or in a quiet corner, they’re as versatile as they are relaxing.

If your dog tends to sprawl on the floor or avoids beds that feel too soft or enclosed, a mattress-style bed could be the perfect fit.

Best for: Dogs who stretch, shift positions, or need orthopeadic support.

Comfort starts with a mattress that suits your dog’s body and habits.

Choosing the Right Dog Mattress Bed: Size and Sleep Style Matter

Not all mattress beds are created equal, and choosing the right one can make a big difference to your dog’s comfort and sleep quality.

Dogs that stretch out fully while sleeping often prefer a flatter, firmer surface. A well-designed mattress bed supports key areas like the hips, spine, and shoulders without sinking too deeply. This makes it ideal for dogs who love to sprawl, lie belly-up, or stretch into every corner of the bed.

Our flat mattress beds are available in four sizes, from Small to Extra-Large. Each one is paired with breed-specific guidance to help you pick the most suitable size. Whether you’re looking for a crate-friendly option or a stylish cushion for your living room, our range offers the versatility to meet every need.

When choosing a size, it helps to measure your dog from nose to tail while standing, then add 10 to 15 centimetres to allow for stretching and movement. Dogs who love to spread out may benefit from even more space, especially larger breeds or those that move around in their sleep.

If you’re unsure which size or style to choose, our quick-reference sizing guide makes the process easier. And if you’d like a second opinion, our friendly team is always happy to help you find the perfect fit.

Simple to Clean and Built for Daily Life

Keeping Your Dog’s Mattress Bed Clean Without the Fuss

Dog beds go through a lot. From muddy paws and loose fur to the occasional spill or accident, they need to be easy to clean to keep up with daily life.

Our mattress beds are designed for hassle-free maintenance. Each cover is fully removable and machine washable at 30°C, making regular cleaning simple and stress-free. The velour outer fabric resists hair, marks and everyday dirt, and can be quickly wiped down between washes.

In between washes, give the surface a quick brush or vacuum to lift loose hair and dust. A damp cloth works well for wiping away small marks or muddy paw prints.

For extra protection, you can add a waterproof liner to shield the inner cushion from moisture, mess or odours. This is a useful option for puppies, senior dogs or after wet walks.

Keeping your dog’s bed clean isn’t just good for your home. A fresh, dry and odour-free sleeping space helps your dog feel more comfortable and settled, encouraging regular use and better rest.

Dog Mattress Beds - Your Questions Answered

What size dog mattress bed does my dog need?

To choose the right size mattress bed, measure your dog from nose to tail while they are standing, then add 10–30cm depending on breed size.

For dogs that like to stretch out, a larger bed gives them space to sprawl. At Collared Creatures, our mattress beds are available in multiple sizes to suit everything from small breeds to large dogs that love to lounge.

Are mattress beds good for dogs with joint problems?

Yes. Mattress beds are an excellent choice for older dogs, large breeds or dogs with arthritis.

Our mattress beds are extra-deep filled to provide full-body orthopaedic support and help relieve pressure on joints.

The flat, open design also makes it easier for dogs with limited mobility to climb in and out comfortably.

Are dog mattress beds comfortable for all sleeping styles?

A mattress bed is ideal for dogs who love to sprawl, stretch out or shift positions as they sleep. The flat, open design offers plenty of room and balanced support without restricting movement.

Our mattress beds use fibre-filled cushions that gently cradle the body and help maintain shape night after night. If your dog prefers curling up or leaning into raised edges, a different style may be better.

What are the benefits of a flat dog bed over a raised or hooded one?

Flat dog beds are ideal for dogs who prefer freedom of movement or don't enjoy burrowing. They offer consistent support across the full surface and are particularly suited to sprawlers, senior dogs and large breeds who need extra space to rest comfortably.

Are Collared Creatures mattress beds suitable for daily use?

Yes. Collared Creatures mattress beds are made with hard-wearing, upholstery-grade fabrics and filled with premium channelled fibre that keeps its shape over time.

They’re designed for everyday use, offering reliable comfort for daytime naps, night time sleep and everything in between.

How do I clean a dog mattress bed?

Cleaning is easy. Our beds have machine washable, zipped outer covers that remove in seconds. Just unzip and wash at 30°C. For extra protection, you can also add a waterproof liner to shield the inner cushion from spills, mud or accidents.

Will my dog actually use the mattress bed?

Most dogs love mattress beds because they offer a familiar, sofa-like surface that’s soft, spacious and supportive.

If your dog currently sleeps on the floor or sofa, a flat mattress bed gives them their own spot to relax without giving up comfort.

Are mattress beds suitable for destructive or chewing dogs?

While no soft bed is fully chew-proof, our mattress beds use tough, upholstery-grade materials that stand up to daily use. For heavy chewers, supervision and enrichment toys can help prevent chewing habits.

What type of mattress is best for dogs?

The best dog mattress provides firm yet gentle support, holds its shape with daily use, and suits your dog's sleeping style. At

Collared Creatures, our mattress beds are filled with premium channelled fibre that distributes weight evenly and cushions joints, making them ideal for dogs who sprawl or shift positions while resting.

Upholstery-grade fabric ensures durability, while the low-profile design makes it easy for older or mobility-limited dogs to get on and off comfortably.

Can I use a dog mattress bed outside or while travelling?

Our mattress beds are designed primarily for indoor use, but they’re lightweight enough to take on car trips or use in a crate. For outdoor use, we recommend placing the bed in a dry, covered area or using a waterproof base.
