This is our second time purchasing this dog bed.  We bought it a few years ago.  It has changed a bit - the foam isn't quite as thick and seems a lighter weight.  But this is the bed our dog loves!  I tried buying a few other beds and they just would not work for her.   She likes to use the sides to put her head on.  She is a chiweenie (part  Chihuahua and part dachshund) - weighs 13 pounds and this bed is a perfect size!
I can't say how it would launder because we have kept it covred.  I use a crib sheet and I tightened up the elastic and it fits great.
