Is There A Way To Firm Up A Soft Mattress? -- Good Questions

Pin it Q: Dear Apartment Therapy readers, I have a great mattress that I love but that my boyfriend can't stand to sleep in (not a joke). He was recently diagnosed with a bulging disc that make soft mattresses very uncomfortable, and while he only spends some nights at my place, his back hurts so badly after sleeping on my mattress that he'll just sleep on the carpeted floor next to me, although this isn't really comfortable for him either...
