Dog Sofa Beds & Mattresses
Some dogs curl into a ball; plenty more flop flat out like a starfish — and those sprawlers need a proper rectangular mattress with room to spare, not a round nest that bunches up.
Extra Large Orthopaedic Dog Sofa Bed
An extra-large orthopaedic sofa bed with a cushioned mattress to support bigger dogs while they sleep.
Orthopaedic Memory Foam Dog Sofa Bed
An orthopaedic memory-foam dog bed with supportive bolster sides for head and neck resting. The egg-crate foam core cushions joints and distributes weight, ideal for older or larger dogs needing extra support.
Cooling Bolster Pet Sofa Bed
Supportive bolster pet bed with a breathable cooling top that keeps dogs and cats comfortable in warmer weather. Raised sides cushion the neck and the cover fully detaches for easy washing.
L-Shaped Bolster Dog Sofa Bed
A roomy sofa-style dog bed with a raised L-shaped bolster along the back and side for support. The flat cushioned base gives large dogs plenty of space to sprawl and rest.
Waterproof Pet Sofa Bed with Bolster
A quilted, waterproof sofa-protector bed with a raised bolster edge for your pet to rest against. The soft top is comfortable while the leak-proof backing shields your sofa from hair, mud and accidents.
Plush Ribbed Mattress Dog Bed
A soft, ribbed faux-fur mattress bed that gives dogs a cosy, supportive place to stretch out and nap. The removable cover is machine washable, and a non-slip base keeps it steady on smooth floors.
Room to stretch, support that lasts
A sofa or mattress-style bed gives a dog the one thing round beds can’t: length. Big breeds and side-sleepers extend their legs fully in deep sleep, and a flat rectangular surface lets them do that without a foot or a tail hanging off onto cold flooring. The trade-off is footprint, so measure the floor space you can spare before you measure the dog.
The filling matters as much as the shape. A shallow polyester pad suits a light, young dog, but a heavier or older dog will press straight through to the floor unless the bed has dense foam or a thick layered core. For genuine joint support, look for high-density or memory foam rather than loose fibre that flattens within weeks.
Bolsters, covers and keeping it clean
Couch-style beds add a raised bolster along one or more sides, giving your dog a built-in pillow to rest a chin on and a reassuring edge to lean against. If your dog likes to stretch fully one minute and prop their head up the next, a three-sided sofa bed is the best of both worlds; for pure sprawlers, a flat open mattress wins.
Whatever you choose, a removable, machine-washable cover is non-negotiable for a bed this size — you won’t fit the whole thing in a domestic machine, but a zip-off cover and a wipe-clean inner liner make weekly freshening realistic. Check the cover is sturdy and the zips are hidden if you have a chewer.
Everything here is chosen to be genuinely useful in everyday life with your pet — quality-checked, fairly priced and shipped tracked across the UK. For any health concern, your vet is always the best first port of call.
Common questions
What size sofa bed should I buy?
Measure your dog lying fully stretched from nose to tail base and add roughly 15–20cm, then check the bed’s internal dimensions rather than its outer size. Sprawlers benefit from going one size up so they never run out of mattress.
Are sofa beds better than donut beds for big dogs?
For dogs that sleep flat on their side, yes — a rectangular mattress supports the whole body, whereas a donut forces them to curl. Donuts suit dogs that genuinely like to nest and feel walled in.
How do I keep a large dog mattress fresh?
Choose one with a removable, machine-washable cover and a wipe-clean inner liner. Vacuum the surface weekly to lift hair, wash the cover every couple of weeks, and air the foam core in the sun occasionally.
