You're spot on Lara! The correct cushion is a must and your article is very helpful indeed I may look into getting a new cushion. I went through several cushions until I found the right one and in the process incurred numerous pressure sores. Even after finding a good cushion I was still getting bothered by pressure sores particularly on my right buttock. Thankfully I use a healing salve that I bought on the internet that has calendula oil, beeswax,patchouli oil and east cape manuka oil amongst other things. I hadn't heard of some of these natural extract but thought, what the heck! and gave it a go. It has healed the three sores on my right buttock and the one on my left plus two on my lower back and it seems to have prevented them from re-appearing. Either that or I have been incredibly lucky.
