It's a trend that's been developing for some time, which is memory foam beds as the best dog beds for pets who have arthritis or creaky joints, or who are just getting older and less limber. You've heard of memory foam beds for humans, in which polyurethane cells in the mattresses mold themselves to the sleeper's body and return to their original shape when the person gets up. These beds provide support like no other mattress, so they've been recommended for humans with spine or joint problems. There's no reason why dog bed furniture of memory foam can't do the same for pets.

The best dog beds for joint problems like this should provide a cushion that reduces pressure, to relieve the pain of the joints themselves and the accompanying muscles. Memory foam gives that sort of support. This is especially good for larger dogs, because many are prone to hip dysplasia, a degenerative joint disease where hip joints don't always fit properly and the muscles near the rump are weak. Large dog beds made of memory foam can relieve aggravation of the affected limbs when the dog lies down, or ease sore muscles on dogs that have worked hard during the day.
