SW Pet Bed’s Chunky Mattress Waterproof Dog Beds

An ideal waterproof dog mattress for country, game and active dogs who get dirty and wet on a frequent basis.

Especially recommended for use as a Dog Crate mattress (Sizes match the 76 cm – 91 cm – 107 cm & 122 cm sizes).

Ideal for both older and younger dogs, these chunky mattress dog beds offer excellent levels of comfort and a great place to dry off.

These dog mattress beds are filled with high density foam encased in a stockinette cover, which acts as a great insulator for cold floors and walls.

The Chunky Mattress polymer bonded foam inner filling is very comfortable and can be removed via zipped edge for washing the outer cover.

Designed to keep your pet warm and comfortable in the winter with polymer bonded foam filler, and cool and breathable in the summer with a tough woven fabric outer layer.


Great for use anywhere indoors such as..

  • Dog crates
  • Back of 4×4 or car boot;
  • Living room;
  • Kitchen;
  • Bedroom;
  • Utility room;
  • Outdoor kennels;
  • and more!

Material is 100% waterproof however if left outisde, rain can eventually soak through sewing seams, saturating the inner filler.

For this reason we suggest using the mat undercover or indoors only.


  • Outer cooling fabric layer keeps the dog cool in the summer;
  • 100% waterproof inner layer;
  • Heavy duty, chew resistant, durable, hard-wearing fabric material;
  • Perfect for nesting and clawing dogs;
  • Easy to keep clean with wiping, hose or jetwash;
  • Chew, dirt, mold, mildew, flea, mite, hair and odour resistant.
