Memory Foam Mattress Dog Bed, Waterproof Liner, Sizes M to 2XL
A flat mattress-style bed with a dense memory foam base for dogs who sprawl rather than curl. The foam sits inside a waterproof liner, so an accident stays out of the foam, and the outer cover zips off for the washing machine. No walls, no bolsters: this is the bed for a dog who wants to stretch out flat, and it fits inside a crate.
Key features
- Memory foam base: a firm, supportive slab that does not bottom out under a heavy dog. Owners describe it as firm rather than plush.
- Waterproof liner: an inner layer between the cover and the foam keeps urine and drool out of the foam itself.
- Removable cover: zips off and machine washes. The plush sleeping surface is a separate zip-off layer, so you can wash that alone.
- Non-slip base: rubberised underside stays put on hard floors.
- Crate-friendly shape: flat rectangle with no raised edges.
Available sizes
| Size | Who it suits |
|---|---|
| M | Medium dogs who sleep curled |
| L | Medium to large dogs |
| XL | Large dogs who sprawl |
| 2XL | Giant breeds and two-dog households |
The maker publishes size labels, not exact dimensions. Measure your dog lying on their side at full stretch, nose to base of tail, and email that number to info@apexflowlabs.com before ordering. We confirm the right size against the current spec sheet before it ships, and a wrong size still gets one free exchange.

Product truth
- Does: give a heavy or older dog a firm, flat surface that is easy to get up from, keep accidents out of the foam, and go through the washing machine in pieces.
- Does not: treat arthritis, hip dysplasia or any joint condition. A supportive surface helps a stiff dog rise more easily; it is not a treatment. A dog that limps, struggles to stand, or is restless at night should see a veterinarian.
- Ships: Domestic delivery only, free over $50, 4 to 10 business days after processing. The foam ships compressed and needs a day to fully expand.
- Wrong size: one free exchange within 30 days on an unused bed.
