Are orthopedic dog beds actually worth it for senior or large dogs?

According to the specialist-subreddit consensus we read on r/dogs and r/seniordogs, yes — owners of senior and large-breed dogs consistently report better sleep and reduced stiffness after switching from a flat cushion to memory or egg-crate foam. The caveat is foam density: cheap orthopedic beds often flatten within months, so look for at least 3-4 inches of foam, a washable cover, and a waterproof liner.
