Hi AdeG welcome to the forum. I can't say that I have any experience of these wedge pillows but I also feel certain that someone in the thread will be along soon to offer some words of advice for you to make the right choice.

hi when i had breast cancer just went to denelm and got a comfy one, didnt use it much for the breast, but when i had this new diagnosis, it definatley helped with the acid reflux, better to go into the range or dunelm if you can so you can try the firmness, was approx £20 with a pillow case from amazon £5.  good luck

I brought a wedge pillow for my dad. Best thing we managed to get since going through the journey. Really has helped him get more comfortable in bed and to sleep. I got mine off Amazon for him. 

Hi AdeG I don’t know how the price compares but we used the Oesophageal Patients Association discount for Putmans. If you go on their website and select support and guidance, the drop down menu list includes bed wedges. Other useful info on there as well.
