We have two dogs and several dog beds for them to choose from. This dog bed is different than the others in that it has an "egg crate" styrofoam interior rather than just stuffing. Our larger (75#) dog likes this one best of all the beds to choose from. Since she is older and larger I was most concerned about her and this has turned out to be a good choice. It appears to be very durable but having used it only a few months I can not really comment on that aspect.
