Warmth is usually the deciding factor
If your cat has ignored every bed you've bought, temperature is the most likely reason. A bed on a cold tiled floor is competing with a radiator, a laptop and a patch of sun, and it will lose every time.
Radiator beds solve this directly. They hang from the radiator itself, putting your cat in the warmest place in the room and off the floor at the same time. They're particularly good for older cats with stiff joints, who feel the cold more than younger ones. Most have a removable cushion and adjustable hooks so they fit different radiator depths.
Height and vantage point
Confident cats like to sleep somewhere they can survey the room. That's why they end up on the back of the sofa or the top of the bookcase.
Hammocks and raised beds work with that instinct rather than against it. Desk beds that clamp to a work surface are worth a look if you work from home and your cat insists on lying across your keyboard. Giving them their own spot at the same height usually settles the problem.
Enclosed beds for nervous cats
Some cats want the opposite. Covered beds, igloo styles and anything with a hood give a cat somewhere it feels hidden, which brings stress levels down. This is the right choice for a rescue cat still settling in, a cat in a busy household, or one that disappears whenever the doorbell goes.
Put an enclosed bed somewhere quiet with its opening facing into the room, not into a wall. Cats want to feel hidden but still be able to see what's coming.
Cardboard loungers
These are cheap, they get used, and they save your furniture. The curved shape suits how cats naturally lie, and the corrugated surface satisfies the urge to scratch. They wear out over a few months, but for the price that's fair, and most take a sprinkle of catnip to get things started.
Getting the size right
Measure your cat from nose to base of tail and add a bit. Cats that curl up tight want a snug bed with raised sides to lean against. Cats that sprawl out flat want something longer and more open. Watch how yours sleeps now and buy accordingly, because a bed that's too big feels exposed and one that's too small won't get used.
Placement matters more than the bed
Off the floor, away from draughts, out of the main walkway. Near a radiator if possible. If your cat has a favourite spot already, put the new bed there rather than expecting the cat to relocate.
Keeping it clean
Look for a removable, washable cover, which most fabric beds have. Wash at 30 degrees with a non-biological detergent, since strong scents put cats off. Vacuum between washes with a rubber brush attachment to lift the hair. Cardboard beds can't be washed, so just shake out the loose bits and replace when they're past it.
