The size was just right.
It's reversible, but mostly fluffy ones use it.

I jumped on both sides in my favorite colors, olive polyester fabric and beige boa! The actual color was better than in the photo, but I cursed my big bee that was attached when I put the boa inside. There is a warning on the product itself that due to the nature of the boa, it can feel tight, so I'd like to know before purchasing. I would be grateful if the bee part could be stretchy.
