If you haven’t replaced your metal spring mattress with a giant block of foam that you bought on the internet, what are you even doing with your life? Today only, Amazon’s marking Zinus 12" foam mattresses down to just $120 for a twin, $160 for a full, or $190 for a queen, all of which are all-time low prices, beating even one-day Gold Box deals.

It’s certainly a little scary buying a mattress sight unseen, but the Zinus boasts a 4.5 star review average from over 7,000 Amazon customers, so it might be worth the risk, at least for a guest room.
