Warm Cuddly Bear: Gentle warmth for little tummies. This sweet cuddly bear is made of soft velour and features a removable heat cushion, perfect for hours of warmth and comfort. Heat source: The cushion contains hypoallergenic, odorless salt that can be safely heated in the microwave (800W for 60 seconds). Unlike natural kernels, the salt does not develop odors, mold, or insects. Relaxing warmth: After heating, simply place the cushion back into the cuddly bear and lay it on the tummy – the warmth soothes colic and abdominal tension. Ergonomic and gentle: The lightweight cuddly bear conforms perfectly to the belly and relaxes with its gentle weight. Easy care: The cuddly bear is machine washable (after removing the cushion).
