Right now I got rid of my old box spring that was falling apart and all I am sleeping on now is my mattress on my floor. I am trying to think of a cheap solution for a good bed type for a allergy suffer. So far what I was thinking of doing was buying a cheap bed platform and just putting my mattress on top of it. Then I wouldn't have to buy another box springs then have to encase it with a allergy barrier. Another option I was thinking of was buying another mattress and placing my mattress on top of the new mattress. I would just buy a new box spring instead of that idea but every time I encase a box spring. The encasement rips. I am also afraid that if I buy a platform for my bed. It will feel unconformable like the way my mattress feels on the floor. Please help me out with some ideas. Thanks.......
