Ordered wedge pillow in the hope that it would help with acid reflux and also post nasal drip at night. Quite firm but fine with pillow on top. Does take a bit of getting used to but I am having much better nights sleep. One downside is that I would have liked a white cover and I am having trouble trying to find spare covers for this size bed wedge, 24"x24"x10" so only 4 stars
