Scruffs Harvard Memory Foam Mattress — Graphite Grey Large

If your dog needs proper orthopaedic support but prefers a flatter sleeping surface, the Harvard Mattress is the one to consider. Designed with older and larger dogs in mind, it uses crumbled memory foam fill to mould to your dog's body shape — distributing weight evenly and relieving pressure on joints and muscles. For dogs with arthritis, hip dysplasia, or the general stiffness that comes with age, that consistent support makes a real difference night after night.

One of the most common problems with memory foam beds is that the fill shifts and domes over time, leaving your dog on an uneven surface. Scruffs have addressed this in the Harvard's improved design — the sleep area stays flat, with the foam distributed evenly so the support doesn't degrade with use.

The Large (100cm x 70cm x 12cm) suits medium to large breeds — Spaniels, Border Collies, Boxers, Dalmatians — with plenty of room to stretch out fully. The herringbone fabric outer in Graphite Grey gives it a contemporary, neutral look that sits well in any home, and the non-slip base keeps it firmly in place on hard floors. The water resistant inner liner adds protection for the foam, and the removable outer cover is machine washable at 30°C.

Frequently Asked Questions

Is the Harvard Mattress suitable for dogs with arthritis or joint problems?
Yes — the crumbled memory foam fill moulds to your dog's body, relieving pressure on joints and muscles. It's a popular choice for older dogs and those with arthritis, hip dysplasia, or other mobility issues.

What's the difference between the Harvard Mattress and the Harvard Box Bed?
The Mattress has a flatter profile (12cm high in Large) without the raised bolster walls of the Box Bed. It's ideal for dogs who prefer to sprawl flat rather than lean against sides, or for dogs who find it easier to step onto a lower surface.

What size dogs is the Large suitable for?
The Large (100cm x 70cm) suits medium to large breeds — Spaniels, Border Collies, Boxers, and Dalmatians. If your dog is a larger breed or likes to fully stretch out, the X Large may be a better fit.

Will the memory foam go flat or lumpy over time?
Scruffs have improved the Harvard design specifically to prevent this. The bed is constructed to keep the sleep surface flat, with the crumbled foam distributed evenly so it doesn't shift or dome with use.

Is the cover easy to remove and wash?
Yes — the outer cover is fully removable and machine washable at 30°C. Don't bleach or tumble dry. The water resistant inner liner keeps the foam protected between washes.

Does it have a non-slip base?
Yes — the Harvard Mattress has a non-slip base, so it stays put on hard floors like wood, tile, or laminate.

Is the Harvard Mattress available in other sizes and colours?
Yes — also available as the Harvard Graphite Grey XL, Harvard Pearl Grey Large, and Harvard Pearl Grey XL.
