Best mattress topper suggestions out there. Any recs? TIA!

Hey Reddit,

I bought a 3-inch mattress topper for my twin bed three months ago and it has already gotten flat after almost 2 months of use (TO HELL with Amazon mattress toppers).

I was a cheapskate when I bought the topper but now I just want to invest in a quality long-lasting mattress topper and there are so many mixed reviews on the few options I have. I am already getting confused!

I weigh around 160 lbs. and usually sleep on my side. I want something comfortable that relieves pressure points because this bed is just too firm. Do you have any suggestions or recommendations?

Thanks in advance!
