I bought this bed for my 17 year old arthritic Maltese.  He was having a tough time stepping up to most of bis dog beds and this one fit the bill. It is very large and he seemed to enjoy stretching out on it    We had three beds of his choosing and this was the one he chose.   I believe he was very comfortable on it.   Sadly our little guy has passed recently, but I felt better knowing he was comfortable during  his last few weeks of his life. 
Update on this bed:I i have changed my review and lowered to three stars. I have not used this bed for my other dogs and decided to take it out recently and use it. (It was only used for a few weeks when i first bought it for my elder dog.) I took the cover off to wash it, followed instructions and when I took it out of the dryer, the zipper was broken. So technically, the bed was used for a total of three weeks and could not withstand the 2nd washing. Very disappointed 

Pros: Easy access for dog, removable cover, machine washable.
