Review: Great size - What a great pillow, finally one that fits inside my oversized king bed shams perfectly, filled it out fully, fluffy but full, has good support, not a soft or a hard pillow just really full all the way to the corners, made very well good quality, but this would actually be a good bed pillow but for me its for my shams & I couldn't be more pleased, highly recommend.
Review: Good quality, inconsistent shipping. - Very good quality & fair pricing. Deliveries were challenging as you can order a maximum of 3 pillows per order. I had to cancel a back order & reorder. Not a big deal but required additional unnecessary follow up on my part.
