Re: Can anyone recommend a wedge pillow?
I'm not sure whether there are any rules on advertising here, so I won't include the link itself but just advise you to google 'acid reflux pillow' and you will see a number of them available. The one I got was the premium one in the range of three and it cost a staggering £79.99 (UK origin - very quickly delivered). It meets the criteria mentioned above, in that it helps maintain a straight line from the hips to the head as it's quite long along the base. It's quite comfortable too and has a removable cover, but since I use it under the lower sheet and have another pillow on top of it, that's not really so important.
But, and it's a big 'but', it takes some getting used to, particularly if, like me, you find it difficult to sleep on your back. I prefer to sleep on my side, and the wedge pillow then makes for an unnatural angle for your spine, which if you already have back issues, is unhelpful. I'm still working at trying to remain on my back, but frequently wake up to find I've changed position whilst asleep.
Would I recommend it? Well, I certainly don't regret getting it, though I wish it had been a tad cheaper, given that it's basically just a piece of foam with a cover on it.
Hope this is helpful. Good luck.
