Hi Kathy, thank you for your feedback. We are happy to hear you found your bbhugme supportive and comfortable! We hold a lot of pride in our products, not only for the value in use, need, and design, but also for the choice of long-lasting sustainable materials both in our inner pillows and our covers. Our patented pebbles are part of the pillow's design and are there to allow the pillow's adjustability. By sliding the pebbles up or down you can choose your preferred pillow's firmness. Depending on the materials that you are wearing when changing the pillow cover, a static shock may appear. There are some sensitive materials, like wool that can trigger the shock. Please mind that we have a 30-day return guarantee and if you are not happy with your purchase, please reach out to us at hello@bbhugme.com to initiate a return. Hugs, bbhugme
