If you’ve been holding out upgrading your bed, Amazon’s pair of Gold Boxes can help.
Get a new memory foam mattress for a heck of a lot less than you’d pay anywhere else. A king size will run you $592, a queen is $517, and a full is $461.
And if you don’t need a mattress but want to add some foam to your sleeping situation, Amazon also has a premium, hypoallergenic pillow for $42.
