Trixie Radiator Cat Bed: Cuddly Bag for Radiator
Last updated: 5 October 2026
The Trixie radiator cat bed is a soft plush hammock on a metal frame that hooks over the top of a radiator, so your cat can sleep in the warm air rising off it. Trixie, the German pet brand, sells it as the Cuddly Bag for Radiator, item 43140. It is 45cm across and takes a cat of up to 5kg.
It costs £32.99 on Amazon UK, sold and shipped by Amazon, and the listing has 4.3 out of 5 from 4,248 ratings. Prices were checked on 5 October 2026.
What the Trixie radiator cat bed is
It is a shallow fabric bag stretched over a metal frame. Adjustable holders hook over the top edge of the radiator and the bed hangs along its front, at whatever height the radiator sits. Inside is a loose cushion that you can flip over when one side gets flat or hairy.
It gives a cat a warm, raised place to sleep without taking up any floor space, which suits a small flat.
Key facts
- Size: 45 x 13 x 33cm. At 45cm across, it is a little wider than a sheet of A3 is long.
- Maximum weight: 5kg.
- Cover: short-haired plush made of polyester, and removable.
- Cushion: reversible, filled with polyester fleece.
- Frame: metal, with holders that adjust between 9 and 12cm.
- Colour: white.
- Fits: Trixie says all conventional radiators.
Who it suits
It suits an indoor cat that already sleeps on the windowsill or the back of the sofa near a radiator. It also suits an older cat that feels the cold, because the bed holds it next to the heat source rather than on a cold floor.
For a kitten or a cat who likes to stretch right out, it is less useful. The bag is 45cm long, so a big cat will curl up in it rather than lie flat.
The limits
Trixie rates the frame for cats up to 5kg. A large cat, or a big breed such as a Maine Coon, can be heavier than that, so weigh yours before you buy.
Measure across the top of your radiator before ordering, because the holders only adjust between 9 and 12cm. Towel rails and designer radiators with unusual shapes may not suit it.
The bed only warms up when the heating is on, so in summer it is just a hammock. Keep it off a radiator that gets too hot to hold your hand against.
Where to buy it
Amazon UK sells the white version at £32.99, sold and shipped by Amazon, with free delivery. You can see Trixie's own specification on the Trixie Cuddly Bag for Radiator product page.
