Hello @ Lvlw
I bought an eggshell mattress topper from Target. It was not expensive, around $40 for a queen size one.
I wanted to try an economical one (read "scunge") before I lashed out and bought an expensive one, just in case it did not work.
Well it works and I won't be lashing out and buying an expensive one as it works.
I find that the eggshell indentations cushion my joints and I also do not suffer as much from night sweats.
The air seems to circulate. I live in a hot humid climate and although I use airconditioning 24 hours a day, prior to buying the topper I was often drenched in night sweats. No longer.
My only grizzle - makes bed making bloody hard. I solved that problem recently by buying king size fitted sheets to go on a queen size bed. Easy bedmaking now.
All the best for your continuing treatment.
Warm Kimberley wishes to you.
