These pillows are handmade using 300TC organic cotton fabric and stuffed with pure eco-grown wool batting. The standard size pillows are available in three thicknesses to suit your comfort: Light Fill, Regular Fill and Extra Thick. The Queen and King Size pillows come in Regular Fill. Organic Pillow Cases for these pillow sizes are available to purchase separately. Holy Lamb also manufacturers other types of pillows, such as the Organic Body Pillow, the Organic Neck Pillow, the Organic Nursing Pillow, and the Organic Wool Pillow. Please know that the air will settle out of your wool pillow with the weight and heat of your head, but will still provide the desired comfort and support.
