I used these, as stated previously, to prop up my sagging mattress and too-low couch. Underneath the mattress I layered them, three- deep across at the lowest point, reducing to two and then one towards the head and foot of the bed.-- with the couch did a similar thing as the bed for the seating as it sagged a little toward the center. Also placed them behind the back cushions. (It sounds like I have trash for furniture -- NOT! -- am just getting older and more demanding of "support.")
