Ive been using a thermarest for the longest time. Mine is a pro lite, 3/4 length women's model. It provides a little more thickness and is a bit smaller.

However ... I've been dealing with back problems and sleeping on it has become quite uncomfortable. I toss and turn all night and my sleep is overall terrible. My back is very very stiff in the morning. Used to be that tossing and turning was actually good for my back as it djdnt let me get settled into one position too long.

Curious if anyone else with back pain has ditched the
Standard thermarest for something else and if so what?

There are many options out there now. Almost too many to choose from. Heard good things about exped ones.
