They looked great and my dogs seemed to enjoy them.  I purchased two large beds and they arrived late last week (Thursday or Friday).  They were setup quickly and easily and all was well in the world.  By Tuesday evening, one of the beds metal support had pulled free so now it’s just an elevated dog mat, as opposed to dog “couch”. I tried to simply re-screw them back in the existing holes and it just wouldn’t hold.  I will try something a little tough like either a glue or bigger screw, or make new holes, which would make the backs different heights.  I’d much like to avoid the latter.  I recall seeing comments of the backs being flimsy and should be supported with a wall.  Those comments are accurate.  Will update if I can successfully “fix” the back on the one, but the makers should look into securing those braces a bit better.
