Features:

• Perfect for reading in bed. This triangular reading pillow provides excellent back support for maximum comfort when you're reading, watching TV, or surfing a laptop. The convenient side pockets can store pens, glasses, remotes, cellphones, etc., to avoid your rummaging of them in bed.
• Alternative headboard without installation required. Most people find it a very sturdy comfy, functional, stable but easy-to-move headboard on platform beds. Its large sizes can prop up at least 2 people at the same time.
• Multipurpose of use. The ergonomic shape brings unparalleled comfort and contours to the shape of your back, shoulders, neck, and legs. Great way to fill the gap between the headboard and mattress.
• Easy to clean. You may remove the pillow cover by unzipping the two-way zipper and unbuttoning each button (fixed on the pillow insert) from the buttonholes (pre-designed on the pillow cover) to get it machine-washed in cold water with a gentle cycle, no bleach, air dry.
• High-quality materials. The back support pillow is stuffed with high-density polyurethane filler, providing contour back support. And the fabric of the wedge pillows has a very good visual effect to match your interior decoration.
• Vacuum-packed shipment. For safe and easy shipping purposes, the product is shipped in a vacuum-packed plastic bag, so you may find the package size is sharply smaller than the product size. When you remove the bag, please give the pillow 2-3 days to recover. Meanwhile, we suggest you knead and pat the pillow to accelerate the recovery process. You can even open the zipper on the lining and then fluff the polyester fiberfill inside and make the pillow more puffy and comfortable.
• Kind notes: The bottom is about 10" thick (not 100% flat). It needs to go against the wall/back frame as a "Standing" headboard & may take up the length of the mattress.
