Seat Pads for Hot Benches: Materials and Use

Why hot benches need a pad

Traditional saunas typically run between 150°F and 195°F, and infrared models range from 110°F to 135°F, according to health guidance from the Cleveland Clinic and sauna manufacturer Finnleo. At these temperatures, the wooden bench can transfer heat directly to your skin, which is why many bathers use a pad or towel to sit on.

A seat pad serves as a barrier between you and the hot surface. It should be made from a material that can handle repeated cycles of heat and humidity without melting, deforming, or releasing odors. The right pad also adds a bit of cushioning, which can improve comfort during longer sessions. If you are deciding between a towel and a dedicated pad, see our compare piece on bench cushions vs towels.

Wood seat pads

Wood is the most traditional choice and matches the interior of most saunas. A wooden seat pad is usually a small slat or board that rests on top of the bench. It is firm, but it does not conduct heat as aggressively as metal or stone, so it provides a stable surface that does not get too hot to the touch. Wood also resists moisture and can be wiped down easily.

Select pads made from species that are already used in sauna construction, such as Nordic spruce, aspen, or western red cedar. These woods tolerate high heat without warping or releasing resin. Avoid painted or glued wood products, because finishes may break down at sauna temperatures. For a deeper look at wood selection, read our guide to sauna wood.

Felt seat pads

Felt pads are softer than wood and are often made from wool or a high-temperature synthetic fiber. Felt provides a cushioned layer that can make sitting on a bench more comfortable, especially during longer sessions. It also absorbs sweat, which can be a benefit if you prefer not to sit directly on wood.

Because felt retains moisture, it needs to be aired out after each use. Many felt pads can be machine washed on a gentle cycle, but always check the care label. Choose a dense felt that will not compress too quickly, and look for a heat rating that matches your sauna's typical temperature. Avoid felt that has a foam or adhesive backing, as these materials may not tolerate heat well. For hygiene tips, see our article on towel on bench cleanliness.

Woven seat pads

Woven pads are made from materials like cotton rope, linen, or natural fiber that is tightly woven. They offer a good balance of softness and airflow, which helps keep the surface from feeling sticky in a hot room. Many have a flat profile and can be draped or tied onto the bench.

The open weave lets heat escape from underneath, reducing the chance of moisture building up. Woven pads are often machine washable and dry quickly. When choosing a woven pad, make sure the fibers are not too rough for your skin and that there are no metal parts that could heat up. A well-made woven pad will hold its shape session after session. If you also use a towel under it, consider the best towel fabrics for heat rooms.

Choosing and caring for a seat pad

When you choose a seat pad, think about the size of your bench and how many people will use it. A pad that is too small may slide around, while one that is too large could overhang and get in the way. Measure the bench width before you buy.

For daily care, wood pads can be wiped with a damp cloth and a mild soap; felt and woven pads should be washed periodically and dried completely. Never leave a damp pad inside a closed sauna, as that can encourage mold and mildew. Check the pad regularly for wear or discoloration, which may signal that the material is beginning to break down. The table below summarizes the three main options.

Safety and placement notes

Always place the pad flat on the bench and make sure it does not extend into the walkway or touch the sauna heater. Keep a safe distance between the pad and any heat source, just as you would with the bench itself. If the pad has a hanging loop, do not let it dangle near the heater. See our heater clearance guide for proper spacing.

Some pads are advertised with safety certifications. Look for a mark from an independent testing laboratory, such as the ETL Listed mark, which indicates the product has been tested to applicable safety standards, according to Intertek, a Nationally Recognized Testing Laboratory. Also, avoid any pad that contains foam, plastic, or heavy adhesives, because these materials can soften or emit fumes at high temperatures.

What to pick for your use

Questions

Can I just use a towel instead?

A towel works in a pinch, but it can slip and does not provide much cushioning. A dedicated seat pad stays in place and is easier to wash. If you use a towel, make sure it is large enough to cover the bench and that it is not too thick to trap heat.

Are foam pads safe in a sauna?

No. Foam is not recommended because it can soften or release odors at high temperatures. Stick with wood, felt, or woven materials that are rated for heat.

How often should I clean my seat pad?

Wood pads can be wiped before and after each session. Felt and woven pads should be washed every few sessions, or more often if they become soiled. Always let them dry completely before storing.

Can I use a seat pad in an infrared sauna?

Yes. Infrared saunas run at lower temperatures than traditional ones, so most wood, felt, or woven pads will work well. Just ensure the material is heat-rated and does not have plastic components.

What should I look for in a heat rating?

Check the product label for a maximum temperature rating. The pad should be able to handle the highest temperature your sauna reaches. Independent certification marks, such as ETL Listed, can provide extra assurance of safety.
