So far, so good.  Feels sturdy well made with lots of cushion for our two chihuahua mixes. We are used to being surprised by items being smaller than anticipated so ordered a medium, both dogs will fit, a small would have worked well.  Our Malachi is a burrower and has to have her head covered when sleeping, slept in it for hours the first day (yes she is in the bed in the second picture, added to show the medium us larger than needed for chihuahua mix.)
Hopefully it holds up
