Matress recommendations something that is actually 4 inches thick
This is my Exped sleeping pad. They make a 4inch one but if you can spend the money and get a 6inch. You will thank me More on reddit.com

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

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

Is a 4" Foam Mattress Enough?
Really depends on the density of the foam. If it’s super dense (like a backpacking camp pad) then 1/2” is enough. If it’s a softer foam, your hip may still hit the wood even at 4” thickness. More on reddit.com

Do I need a mattress protector for a twin mattress?
A mattress protector is highly recommended. It helps keep the twin mattress clean by guarding against spills, sweat, dust, and allergens, and it can significantly extend the life of the mattress, especially in kids' rooms or guest spaces.

Temperature can depend on the materials and covers used. Mattresses with breathable fabrics, open-cell foams, cooling gel, or coil support cores tend to allow more airflow and feel cooler than very dense, unventilated foams. Look for any cooling features...

r/urbancarliving on Reddit: Matress recommendations something that is actually 4 inches thick
January 8, 2025 -

I've bought 2 camping (memory foam/hd foam) mattresses off Amazon and they both promised to be 4 inches but were only 2.5. Not sure why. Is there an honest company on amazon that will send me an actual 4 inch matress that is supportive for a side sleeper? Would be great if it could be 75 inches long. Thanks!
