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 this Zinus 12” gel-infused foam mattress down to just $109-$246 for Cyber Monday, with queens checking in at $180.

Interestingly, Amazon’s also running big discounts on the iconic Casper mattresses; much larger than you’d ever see on Casper’s own website. The queen is down to $760, which is $190 off, and other sizes have similarly sizable discounts. You’ll also get the same 10 year warranty and 100 night trial period that you’d enjoy if you bought from Casper directly.
