This bed seems like it is very sturdy and well made, but due to the drainage holes it inflates full of air as soon as my dog gets up, then he is too scared to get on it again, because once filled with air it is unstable under his feet (imagine the feeling of stepping on to a waterbed).  I need to climb on it first on my hands and knees to deflate it prior to him being willing to get on it. I could leave the cover unzipped, but then it is no longer waterproof!   Lastly- it came with about double the amount of stuffing needed, so one could save that to re-fluff it in about a year, if needed.
