Cats sleep better with something against their back. A flat mat leaves them exposed on every side, which is why so many end up in a cardboard box instead of the bed you bought them. Deep sides solve it: the cat curls, presses into the wall of the bed and settles properly, and in a cold room those sides hold their own body warmth around them rather than letting it drift off across the floor.

This one is a thickened round nest in green with festive styling, filled and walled generously enough to burrow into rather than merely sit on. The round shape matters for a curled cat, because there are no corners to leave a gap at the back, so whichever way they turn there is a side to lean against. Three diameters are offered, 40 cm, 50 cm and 60 cm, and the bed weighs between 700 g and 900 g.

• Deep sides for burrowing and leaning against
• Thickened, warm build for cold rooms
• Round shape suits a curled-up cat
• Three sizes: 40 cm, 50 cm or 60 cm diameter
• Green, with festive styling
• Weighs 700 g to 900 g

On choosing a size. Bigger is not better with a nest bed, because a cat who cannot reach the sides gets none of the benefit. Measure your cat curled up and add a little, rather than sizing up out of generosity. No washing instructions are published, so treat it as a hand-wash and air-dry item until we can confirm otherwise, and expect the seasonal styling to be a seasonal taste.

Who it's for: Cats who nest, burrow and disappear into things, in houses that get properly cold over winter.
