Book Reading Wife Approved
Size: Standard (18-Inch), Color: Sage Green
I purchased this for my wife who reads quite a bit and she absolutely loves it. She said it feels soft, is the right size for her, and makes book reading more comfortable for her. I call it a win.

Heaven sent
Size: Jumbo (25-Inch), Color: Dark Grey
My back suddenly decided to show me who's the boss. This reading pillow has been a God send! It is substantial without being too hard, soft enough to be comfortable without being too soft, absolutely no lumps! The outside cover is removable to allow for machine washing and is so soft to the touch. There is a handle on the back that makes it easy to move. This has allowed me to be able to sit upright, much appreciated!

Huge, super soft, cozy pillow!
Size: Jumbo (25-Inch), Color: Sage
This pillow is awesome! As a plus size person who can't sleep laying flat, the size and support level is perfect. This pillow is huge! The quality is very high, the stitching is precise, and the sage green material is soft and cozy. Great value for the price! I highly recommend this reading pillow!
