Sitting on a real sea anemone would be unwise - unless you're secretly a clownfish. This removable, machine washable bean bag cover is fun for pretend, or as a fidget toy and is comfortable to sit on. It measures approximately 24 inches in diameter, 12 inches high, with tentacles that are also 12 inches long, and closes with an invisible zipper on the underside that runs nearly the full diameter for ease of stuffing. Important note: this is the cover only and arrives without any stuffing in the body - the tentacles are lightly stuffed for shape. You can stuff it with a bean bag, stuffed animals, the blankets that get kicked off the bed in the night. (or is that just my kid). Due to the amount of fabric required, this item is made-to-order, and the photos are for demonstration purposes only.
