Hi Rachel,
What Bronson said is really the only way to do it but, for an extra 2.5' I would probably not do it unless you have more money than I do

If you are considering moving again in months to come, I would not do it because those mats are expensive and I personally could not afford to do it. However like I said, if you can afford to replace them, go for it. I don't know if you will be able to feel the extra 2.5' to the point it is worth it?
