Amazon mattress you've tried and liked. Any suggestions?

Hey all,

I'm looking for a new mattress and, honestly, I'm kinda lost. Just moved into my first solo apartment (yay for adulting, right?), and the mattress I inherited from my old roommate is a no-go; way too firm for me.

I'm not too picky about firmnesses… I’m 175 lbs. and I sleep on my side. But, it’s common sense: it CANNOT be this FIRM. No health issues to speak of, unless you count a chronic case of indecision. Amazon seems to have some good options, but those reviews seem pretty fake.

Does anyone have any go-to brands or specific mattresses they've bought off Amazon and liked? Any advice or suggestions would be highly appreciated. BTW, love this sub!

TIA!
