Should I go 4 inch or 6 inch

I am grateful for the 6 inch when I sleep on it. I wish I had got the 4 inch when I have to store it. If I had it to do over, I would still get the 6 inch. More on reddit.com

Recs for a ~4 inch full size mattress? It's going in a van

I bought the, either Zinus, or some other brand that was Green Tea themed, off Amazon for my van. Don’t remember cause it was like four years ago. It might be a 6” tho, not a 4. It’s super comfy with a 1” egg shell on top. Check out Amazon for 4” mattresses. They ship in a box and come rolled up, and then ‘inflate’ when you roll them out. And they’re easy to shove into the corners of your van if your bed is slightly smaller than a standard mattress size. These beds I find to be “firm” so look for a topper if you need extra squish. Good luck! More on reddit.com

Sleeping on the floor on a 4 inch foam mattress-bad??

If you are trying to transition to a side sleeper, try adding a body pillow. When you sleep on your side and hug it, you have your body touching the body pillow and that helps simulate sleeping on your stomach. That helped me. More on reddit.com
