What we don't know

Bestpet haven't told us whether this is machine-washable or which specific plastic bed models it fits, so if you already own a plastic bed shell, it's worth checking the liner's size against it before ordering.

Why we chose it

A liner is a cheaper way to make an existing plastic bed usable than replacing the whole thing, which is the practical reason to stock it as a separate item. Fifty centimetres also suits the more common small plastic bed size rather than needing several sizes on the shelf.

Size guide & how to measure

A good bed lets your pet stretch out and curl up. Measure your pet nose-to-tail while they’re lying down, then add room to move.

How to measure

Measure your pet from nose to base of tail while lying relaxed.
Add roughly 15–25 cm so they can stretch out fully.
For pets that like to curl, you can size down slightly for a snug, den-like feel.

Size	Typical internal length	Rough guide
S	up to ~50 cm	Cats, toy & small breeds
M	~50–70 cm	Small–medium dogs
L	~70–90 cm	Medium–large dogs
XL	90 cm +	Large & giant breeds

Ranges are approximate and vary by style. Always check this product’s Specifications for its exact dimensions.

Full description

A hard plastic bed shell is easy to clean but not something most animals would choose to lie directly on, which is what a liner is for rather than the bed itself.

Bestpet's Cosy Cushion Liner is a 50cm soft liner designed to fit inside plastic pet beds, adding a padded, supportive surface on top of the moulded shell. It's aimed at cats, small dogs and other small pets.

Designed for use inside plastic beds
Adds softness and warmth over a hard shell
Suits cats, small dogs and other small pets

What we don't know. Bestpet haven't told us whether this is machine-washable or which specific plastic bed models it fits, so if you already own a plastic bed shell, it's worth checking the liner's size against it before ordering.

Who it's for: owners with an existing hard plastic bed shell wanting a softer surface to put inside it, for a cat, small dog or similarly sized pet.
