Orthopedic bed firmness, explained in plain language

"Orthopedic" isn't a regulated term — any bed can be labeled that way. What actually protects an arthritic dog's joints is foam density and layer construction, which is printed in the specs, not the marketing copy.

Editor's pick Multi-layer orthopedic Firm support base under a softer top layer. 2.5–3.5 lb/ft³ (ILD 40–50) 5–7″ Senior or arthritic dogs, any size View →
Single-layer memory foamConforms to the body, no firm base. 2.5–3.0 lb/ft³ (ILD 10–14) 3–4″ Younger, mobile dogs without joint issues View →
Bolstered / donut bedRaised rim, soft fill, minimal base support. Not usually rated 2–4″ Dogs who like to curl up, no mobility concerns View →

What we'd look for

  • A base layer specifically rated 2.5+ lb/ft³ density — this is what stops the bed compressing flat under weight over months of use
  • At least 4″ total thickness for a medium dog, 6″+ for large breeds
  • A removable, machine-washable cover — accidents and joint creams get on these beds

What we'd flag

  • Listings that say "orthopedic" but list no density or ILD number at all
  • Beds under 3″ thick marketed for large or senior dogs — they'll compress to the floor within weeks
  • Memory foam alone with no firmer base layer underneath — comfortable at first, but it packs down and stops supporting hips within a few months
