Depends on your weight and sleep style. Thin built back and belly sleepers will need less than side sleeping thicker folks. I recommend going thicker. Nothing more miserable than not getting sleep due to discomfort. You might get away with thin if you have a dense sleeping pad underneath. Answer from RTMalthus on reddit.com

3 weeks ago - The low cost makes it perfect for temporary living situations (like summer camp or college dorms), and it's more compact than thick foam toppers, so you can easily pack it up and bring it with you. This one also stands out for its stretchy sides that tuck under the mattress just like a fitted sheet. It's generously sized to fit tall beds up to 21 inches high.
Desperately Seeking a High Quality ~6" latex(?) mattress or mattress topper . . .
If you don't mind going to 8 inches, the Sleep On Latex in firm would probably be be a great fit. https://sleeponlatex.com/products/natural-latex-mattress More on reddit.com

December 28, 2024Should 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

April 29, 2024Recently bought a 6 inch mattress with memory foam, is that too thin to be worth it?
That's pretty thin for an adult. If you like it REAL firm, you'll love it. Just make sure your box/bed furniture is flat and solid like a board. If you put something that thin directly on slats or bars you will probably feel them through the mattress. If you don't want it that firm, or your bed support is not totally flat and smooth, adding additional foam padding can help. Check to see if it's more cost effective to get a thicker mattress instead, or just add a topper, or another skinny foam mattress. More on reddit.com

March 24, 2019What R Value would a 6" Memory Foam Mattress Provide?
The problem with memory foam is that is absorbs moisture like a damned wick. So, in an outdoor setting, you're going to get damp and moldy memory foam in a short time. Get yourself a waterproof cover than encases it completely. More on reddit.com

r/vandwellers on Reddit: Memory foam mattress topper: thickness?
June 30, 2023 -
I am going to get a memory foam mattress topper as my mattress. I want something relatively thin because my van is small. I was thinking of getting a 3 or 4 inch one but I'm worried it would be uncomfortable (the topper is going to be the whole mattress, I won't have anything underneath). For people that are using memory foam toppers as mattresses, what thickness would you recommend?

If I recall correctly memory foam turns hard in cold weather. Just a friendly reminder!

9 Best Plush Mattress Toppers 2025 | The Strategist
October 10, 2025 - From the maker of some of our favorite bed pillows and body pillows, Coop Sleep Goods, this topper is filled with the brand’s well-loved crosscut memory-foam-and-microfiber blend (which you’ll also find in its pillows). That makes it a good option for anyone with an allergy or aversion to down. At an extra-cushy five inches thick, this topper has the highest loft on this list and is designed to add a pillow-top-like feel to your mattress — and I would say it succeeds.
