Do not fall into the trap of those telling you that you don't need a rug pad under your carpet, or that it won't offer you much in terms of carpet protection and added utility. Those people are usually the ones whose carpets break down after a few years, either because of excessive wear and tear without a rug pad to alleviate some of the load or because they are not diligent with their carpet maintenance. In truth, getting a quality rug pad for your carpet is just another form of maintenance, and it shows a level of care for one's carpet that will allow it to stay pristine for long periods of time. Another reason the naysayers don't advocate rug pads is because of their cost. A single 5 x 8 rug pad made from a cheap material costs almost nothing, whereas a couple of high quality 8 x 10 rug pads can cost several hundreds of dollars. There is also the option to get a free rug pad from your rug vendor, but with the level of quality these rug pads have, you are usually better off waiting until you can afford a proper rug pad made from quality materials and one that is suited for your carpet something you must check for with the manufacturer as the incorrect rug pad can ruin your carpet. Think about the location of your carpet and ask yourself: what is missing? Your carpet might be providing an insufficient level of comfort for you, your family and friends that like to sit and walk on the carpet without shoes. If this is the case, consider either getting a prime foam or a wool rug pad. Since prime foam is synthetic, many instead prefer to use wool, but caution needs to be exercised when cleaning related to the humidity level in the room, as fiber rug pads can rot, developing a foul odor and almost certainly requiring you to replace them. Maybe you have two medium sized carpets in your home and need some 8 x 10 rug pads that will offer support against the furniture pressing into the carpet. This is a common problem for people who do not wish to rearrange their rooms but also don't want a smaller carpet on their floor. In this case, density is the key, and you need to look for a very sturdy rug pad offering the best possible support in the face of constant pressure from heavy furniture. Using a hard material such as flat rubber or frothed foam will ensure your beloved carpet doesn't contract any of those nasty furniture indentations not only do they look ugly and ruin the overall look of the carpet, they can also be impossible to get rid of once the furniture has rested on top of the carpet for long enough. These are only some of the options available when choosing your rug pad material, and you need to take the time to carefully study the good and bad sides of every material and see how it translates to your budget restrictions before making a decision.
