The dangers of your living room couch go beyond living a sedentary lifestyle. To begin with, most couches are sprayed with flame-retardant chemicals and made from chemical-laden fabrics. Polyurethane foam used in some fillings can release toxins over time while adhesives used to bind wood together contain formaldehyde. Plus, if you spend a lot of time on your couch, sweat, dead skin cells, and dust all build up on the fabric over time.
Cleaning your couch regularly by washing or vacuuming the cushions will get rid of that build up. You should also avoid sitting on ripped upholstery that exposes you to polyurethane and formaldehyde or use a couch cover to keep your furniture in good shape. Finally, eliminating toxic chemicals by buying food made from natural materials like wool, feathers, leather, or wood also reduces exposure.
