Hover to zoomSize guide & how to measure
A good bed lets your dog stretch out and curl up. Measure your dog nose-to-tail while they’re lying down, then add room to move.
How to measure
- Measure your dog 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 | 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 base isn't something most pets would choose to lie on directly, which is the entire reason a liner exists rather than being an optional extra.
The Bestpets Cosy Cushion Liner is designed to go inside a plastic bed base, adding a soft, supportive layer that Best Pets say helps a pet feel warmer and more secure. It's available in multiple sizes, is easy to clean, and is suited to cats, small dogs and other small pets.
- Designed to fit inside a plastic bed base
- Available in multiple sizes
- Easy to clean and maintain
- Suited to cats, small dogs and other small pets
- Aimed at warmth and support rather than just padding
On sizing. This card doesn't give us a size chart or the dimensions of each option against a specific plastic bed model, so match the liner to the base you already own by size rather than assuming one liner fits every plastic bed on the market.
Who it's for: owners of a plastic pet bed base who want a soft, washable liner rather than using the hard plastic on its own.

Why we chose it
A liner that's actually sold to match our own plastic bed range is the reason it's stocked as a pairing rather than a standalone item — buying a liner that doesn't fit the base defeats the point. Being easy to clean also matters more on bedding than almost anything else in the shop.
— Matt, founder
