I saw the wedge while shopping for a mattress pad. Somewhere in the text for the item it mentioned that it could ease GIRD, so I bought it to see if it would help my husband. We've been using it for three or 4 weeks and I have to say that, while it did not eliminate his GIRD, it did in fact reduce the amount of intense coughing he suffered caused by GIRD. It is comfortable and we sleep well. We use the deep pocket sheets but it's a tight fit to get them to go over the mattress and the wedge.
