Tri-Core Pillow, Standard Size. I bought this pillow at the advice of my physical therapist for my pain in the neck.
About the product, from the vendor website: "The unique, trapezoid center gently cradles your head and supports the neck in its natural position."
About the product, from my real life: "The unique, trapezoid center gently cradles your cat in their favorite ball-like sleeping position." In fact, there has not been a night in recent memory when I have not awoken with my head on the outer rim of the Tri-Core Pillow and Lola or Kitty curled up in the trapezoid center. And fur balls further reveal that Kitty has been taking naps in the pillow when I'm at work.
I sort of love this, of course, but $35.00 was for a pillow, not a cat bed.
June 13, 2011 update: Woke up to Lulu in the trapezoid center. This is getting ridiculous.
