Why Wool Rugs Need Rug Pads (and Why Size Matters)

All wool rugs, no matter type, thickness, or size, need rug pads to protect them and the floors they lie on. Most high-quality area rugs are made of wool, a naturally soft and durable material that absorbs color well and typically lasts for generations.

Many traditional wool rugs, like dhurries and kilims, fall into the category of flatweaves, which can be thin and so tend to wrinkle, buckle, and slip. Non-slip rugs pads can help keep these rugs lying flat in and in place. The most traditional and handmade versions of these wool rugs may also have rough backings, so solid-style rug pads will protect your floors from scratches as well as offering a softer feel under foot.

No matter what kind of wool rug you have, the right, high-quality rug pad will protect your floors from scratches, spills, and stains while protecting your wool rug from furniture indentations, stabilizing it to facilitate vacuuming, providing a buffer to minimize wear and tear, and increasing air flow to keep it cleaner every day. Rugs pads also offer stability and cushion, but the balance of grip and cushion you’ll need and want in a pad depends, in large part, on the size and weight of your wool rug.

In general, smaller rugs and runners need more grip while larger rugs need less grip and are often placed in rooms where you want to enjoy a bit more cushion, like living rooms and bedrooms.

You may also want to consider the type and thickness of your rug. For example, though larger wool rugs are generally anchored by furniture and their own weight and don’t need pads with grip, thinner wool rugs like flatweaves, even large ones, may need pads that offer grip as well as cushion.

Fortunately, there are a range of options available in rug pads with strong grip and low-profile, a combination of grip and cushion in a range of thicknesses, and the thickest pads offering the most luxurious cushioning.

For small wool rugs and runners

Scatter rugs, throw rugs, and runners need rug pads with a strong grip to keep them in place. Because they tend to be placed in high-traffic wools and in hallways, where door clearance can be an issue, low-profile non-slip pads are usually the best choice for these rugs.

• Small rugs shift, slide, and wrinkle without a non-slip rug pad, especially in high traffic areas
• Non-slip rug pads keep a low-profile and won't raise rugs too high off of the ground

For the lowest profile and strongest grip, consider a classic, non-slip open-weave, waffle-design pad or a solid version combining rubber with a bit of felt.

For great grip with a subtle cushion, consider Super-Lock Natural. This classic waffle-style pad made with over 1 pound of natural rubber per square yard that’s thin enough to keep rugs in place while facilitating air flow, protecting floors, and keeping small rugs and runners lying flat. While this pad may look identical to plastic versions of the same rug pad type, it’s different. Made with primarily 100% natural rubber, this pad will grip better than plastic pads, won’t outgas, and will never strip, stain, or stick to floors as plastic pads made with synthetic adhesives can. It’s also denser and heavier than comparable and PVC pads and will last longer, perform better, and offer a bit of cushion that won’t compress over time.

Nature’s Grip is another great, eco-friendly choice that is more sustainable than what's currently on the market. Nature’s Grip weds hand-woven organic jute fibers to natural rubber to maximize your rug’s grip, protect your flooring and extend your rug's life. In this pad, natural rubber is combined with a plant jute base, one of the strongest naturally- produced materials available. Naturally safer than plastic non-skid pads, Nature’s Grip and will actually grip to floors rather than sticking to them. Nature’s Grip’s low profile is a choice when door clearance or rug thickness is an issue. It’s also a favorite for runners and scatter rugs that should lie flat with flooring.

For a solid take on maximum grip and minimal lift, consider RugPro, low-profile, high-performance pad that works particularly well in high traffic wools and in hallways and doorways. This pad’s solid design offers more floor coverage than traditional waffle-style non-slip pad, making it a particularly good choice for small wool rugs and runners with rough backings as it protects floors from scratches. This design also keeps dirt from accumulating and reaching your floors and makes vacuuming easier, effectively extending the life of your rug by helping to keep it clean (especially important when you consider that dirt is the #1 cause of rug degradation; keeping your wool rug clean keeps it young!) RugPro is also needle-punched using very small holes to allow rugs and floors to breathe by improving airflow.

For medium size wool rugs (roughly 4'x6' to 5'x9')

For wool rugs that fall into this general size range, you’ll likely want some balance of grip and cushion. Look for pads that combine felt cushioning with natural rubber, the strongest gripping, longest lasting, safest and most eco-friendly material for keeping rugs lying flat and in place. The felt used in the high-quality pads listed here are made from new, unused, recycled rug and carpet fibers heat pressed so it won’t compress and retains its loft and cushion for many years.

Beyond the combination of rubber and felt, you want to look for pads engineered and designed for great grip. The best rubber and felt rug pads are made by heat pressing the top of the felt so it grabs the bottom of the rugs, almost like Velcro, but more gently (like a strong hug.) This keeps the rug lying flat against the pad. The rubber bottom then tightly grips floors (without sticking to them or staining them, the way some synthetic adhesives can) keeping rugs stable and smooth.

• A dense felt surface adds cushion and attaches to the rug backing.
• A reinforced natural rubber backing keeps rug firmly in place on the floor.

Three of the best pads on the market today offer this combination of materials and engineering with varying levels of cushion and lift.

For maximum grip with a minimal lift, consider RugPro, a low-profile, high-performance pad that works particularly well in high traffic wools and in hallways and doorways, where door clearance may be an issue. This pad’s solid design offers more floor coverage than traditional waffle-style non-slip pad, keeping dirt from accumulating and reaching your floors and making vacuuming easier, effectively extending the life of your rug by helping to keep it clean (especially important when you consider that dirt is the #1 cause of rug degradation; keeping your rug clean keeps it young!) RugPro is also needle-punched using very small holes to allow rugs and floors to breathe by improving airflow.

If you’d like a bit of cushion under your rugs but still need to keep a relatively low profile, consider Contour-Lock. This 1/8 inch-thick felt and rubber pad offers a strong grip and moderate levels of cushioning without bulking. Rugs often tend to have rough backings, so this pad’s slightly thicker solid design not only helps keeps rugs clean, but fully protects floors from scratches. This pad offers a great overall value for reliable grip and subtle cushioning.

For more cushion, particularly under rugs in living rooms, dining rooms and bedrooms, there’s Superior-Lock, combining the best of both grip and cushion. Made with more felt and a gentle heat-pressing technique, Superior Lock offers unyielding, non-slip traction with thick, cushioned support. It’s essentially a thick layer of felt combined with a thinner non-slip, natural rubber pad. The needle-punched felt surface naturally clings to the bottom of rugs to anchor it to its surface, giving your rugs the ‘hug’ they need while giving you extra softness and comfort in two thicknesses, 1/4 inch and 7/16 inch, the best choice for maximum comfort under rugs.

For large or oversized wool rugs (8'x10' or larger)

In general, larger rugs call for cushioned pads versus non-slip pads. Most large rugs, especially those heavier, thicker pile, remain stable on their own and are often held in place by furniture so they don’t require pads with grip. However, some thinner large rugs (like flatweaves) may need pads with a combination of cushion and grip (see suggestions for Medium Sized Wool Rugs above.)

• Larger rugs don't usually need a nonslip pad because they are kept in place by their own weight or surrounding furniture
• The one exception to this is thin flatweave rugs that wrinkle easily and should be paired with a felt and rubber pad (see above)

For large rugs that don’t require any grip, a variety of pads offer great cushion, floor protection, sound-proofing, insulation, and varying levels of lift.

Tightly woven of 100% recycled new, unused carpet fibers and yarn, Eco-Plush felt pads are heat-pressed to last longer and feel softer and maintaining their lift and cushion for many years.

Eco-Plush felt pads contribute to the LEED point rating system of the U.S. Green Building Council for low emissions, design innovation, and recycled content. They’re also resistant to mold, moisture, mildew and odor-causing bacteria.

For the ultimate in luxurious cushion, Cloud Comfort pads are made with the same type of 100% viscoelastic memory foam used in premium mattresses. These pads are specifically engineered to provide comfort for you as well as a supportive layer of protection for larger wool rugs that lie flat on their own and do not require non-slip pads and the floors they lie on. They are completely safe for all floors and finishes, including hardwoods and laminates, tile, stone, and marble. Cloud Comfort’s proprietary moisture barrier protects floors by blocking spills while at the same time allowing vapor to escape.
