Kids are more prone to getting the carpet dirty. Of course you already know that! The best way to combat this is to select a carpet with a lower pile. This will help make the carpet easier to clean should it get dirty because the vacuum can get right down there a get all the dirt out. As a general guideline aim for a pile to longer than 1/3 of an inch.
An added bonus if a low pile is the increased durability it brings.
Note the fiber the rug is made out of. Is it natural or synthetic? Synthetic fibers such as nylon or polypropylene are made from a type of plastic. We recommend these types of fibers are they are more durable and can help avoid stains.
Also take note of where you are buying it. If you choose to purchase the rug online make sure you check out the merchant before buying. Confirm that they have a return policy in case you are unsatisfied with the rug. Also check their shipping charges, some merchants charge more than others. One final tip is to check weather or not they charge tax, if your buying an expensive rug this can equal substantial savings for you.
