Can I use a mattress topper to make my current mattress feel bigger?
No. Mattress toppers add comfort but don't change physical dimensions. So they can't make your bed wider or longer. If you need more sleeping space, you must buy a larger mattress size.

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!

I could go wider too, I’d have to cut it up to shape it but I’d have a little bit of an L shape in the back for more space 🤔 I could also just use my current foam pads and make the L shape that way. I don’t even utilize much of that L anyways 🤔
