I bought this mattress for my 11 year old pitbull. She’s an old lady who has recently been diagnosed with spondylosis of the spine at her L6-L7 and L7-S1 vertebrae. We got this in preparation for her neurosurgery to mitigate her spinal issues. I expected the material the bed was made of to be far more...forgiving? It’s very rigid, stiff and I’m honestly surprised. Now, I will say the bed is very well constructed. The material seems to be of high quality. The cover is nice as well. My dog is gets in her bed and shuffles/tosses her blankets around until she is nestled underneath them in a cotton pseudo cocoon. I assumed the material this bed was made of would be conforming and have a bit more give in it; more cushion-y. A bit disappointed but it’s still nice (and I have already recycled the box so i won’t be sending it back. I’d like to see this product reimagined with a softer, perhaps , less dense primary material.
