What is the best way to raise...

Our local expert (Earl Proulx from Yankee Magazine) offers two methods: (1) Place an ice cube in each dent and allow it to melt. While the carpet is still damp, use your fingers to fluff up the fibers. Then allow it to dry. If these are very deep dents, you may have to repeat the process. (2) Use a steam iron to steam the indented area for a minute or two, then fluff the fibers with a comb. If the carpet is synthetic, avoid touching the hot iron to the carpet fibers. When you replace your furniture, try to avoid putting the legs back in the same spots.
