This wedge is more of an extra support for reading in bed, than a sleep aid so your pillows don't slide into the gap between mattress & headboard. It won't serve the intended purpose for me. I got a crook in my neck the first night, even after sliding down in my bed.

It’s good that I ordered another one. Its a perfect fit for the playpen.

Perfect! Sizing is great for my full and queen beds.

Comes rolled up in a small box instead of shipped full size, which affects the firmness of the pillow wedge. Again, rubber whether flat or foam has a memory and rolling up items to save on shipping costs adversely impacts the quality of the item. It took a while to pop up to normal size. I believe the pillow being rolled up affected the firmness of the pillow. The shape of the wedge pillow does fit in between the gap between mattress and headboard. If the customer is very tall, they should take into consideration the head space occupied by the wedge pillow and the length of the mattress. Please let your customers know if pillows are being shipped rolled up - it does make a difference. Customers should have all the facts regarding the product and packaging to make an informative decision before buying a product to ensure customer satisfaction. I do not prefer pillows rolled up which lowered the rating.

It works well. If you have that gap between the headboard and mattress this pillow will work.
