Very disappointed with this product.
We were impressed with the all year side of it as advertised but have found that once fleece is removed it wouldn’t be a cool bird to sleep on.
The bolster surround also doesn’t fill the casing so is a bit saggy.
But for the fact that the memory foam mattress expands  after opening we would have sent it back.
We are so disappointed we haven’t even shown it to our Golden Retriever.
We won’t be buying on line again.
