Bench Cushions vs a Plain Towel

Why a Plain Towel Works

The simplest way to protect both your skin and the bench is a towel. It sits between you and the hot wood, absorbs sweat, and washes easily. Unlike a permanent pad, you can take it out and clean it after every session, which is the hygienic choice for any shared or solo sauna.

A towel also lets air circulate around the wood. When you sit directly on a wet towel, some moisture wicks through to the bench, but a dry towel and a little spacing between slats allows the wood to breathe. If you use a towel that is large enough to cover the entire seat, you also avoid direct skin contact with any splinters or rough areas.

Traditional saunas typically stay below 20% humidity, according to Cleveland Clinic, so the main moisture you bring in is your own sweat. A cotton or linen towel handles that exceptionally well and dries quickly between uses.

What a Bench Cushion Adds

Cushions offer more padding, which can be a relief for anyone who finds a flat wooden bench uncomfortable, especially during longer sessions or for those with joint pain. However, a cushion is only a good choice if it is designed for sauna conditions. Look for materials that are heat-resistant, non-porous or easy to clean, and that allow air to reach the bench.

Some cushions are made from foam that cannot tolerate high heat, while others have fabric covers that may trap sweat. In a traditional sauna with temperatures between 150°F and 195°F (as noted by Cleveland Clinic), the wrong material can soften, off-gas, or even become a burn risk. Always check the product's heat rating and care instructions before using it in a hot room.

For infrared saunas, which typically run cooler at 110°F to 135°F per Cleveland Clinic, the heat tolerance requirement is lower, but moisture management is still important. A cushion that traps sweat can lead to the same wood problems as a wet towel left in place.

How Each Option Affects the Wood

The primary enemy of sauna wood is unmanaged moisture. Sweat that stays in contact with the bench can lead to staining, mold, and over time, warping or cracking. A towel absorbs sweat and keeps it away from the wood; a cushion that holds moisture against the bench can do the opposite.

Finnleo's FAQ notes that carpet should never be used in a sauna because it absorbs sweat and odors. The same logic applies to any cushion with an absorbent, non-washable cover. If you choose a cushion, make sure the cover is removable and machine-washable, or the cushion is made of a material that can be wiped down after each use.

Proper airflow matters. Some cushions are designed with a breathable mesh or have a structure that lifts your body slightly off the bench, allowing air to circulate. That helps the wood dry between sessions. Learn more about Floor Mats and Can You Oil Benches? What to Use and What to Avoid.

Choosing Based on Your Sauna and Sessions

If you use a traditional sauna with high heat and low humidity, a towel is almost always the simplest, safest choice. It handles the heat well as long as it's cotton or linen, absorbs sweat, and can be laundered. For infrared use, where temperatures are lower and sessions may be longer, a cushion designed for that climate can add comfort without damaging the wood.

Consider your session length. If you typically stay 10 to 20 minutes as Finnleo recommends, a towel may be all you need. If you're planning longer, meditative sessions or have mobility issues, a cushion might be worth the extra care.

Hygiene is another factor. If the sauna is shared, a towel that you bring and take away is the most personal and sanitary option. A permanent cushion can harbor odors and bacteria unless cleaned meticulously. See How Many Towels to Bring for a Sauna Session and Towel Size and Fabric for tips.

Remember that your choice also affects how often you need to clean the bench itself; a towel simplifies that routine.

Care and Maintenance

Whatever you sit on, keep the bench itself clean. Wipe down the wood after each session to remove sweat residue, and let the sauna air out. If you use a towel, wash it after every use in hot water. If you use a cushion with a removable cover, follow the manufacturer's care instructions, and avoid letting the cover stay damp.

Inspect the bench periodically for splinters or worn areas. A towel can hide damage, so take it off occasionally and check the wood underneath. Treat the wood with a food-safe mineral oil or a proper sauna sealant to keep it in good condition. For more on bench care, see Sanding and Smoothing Benches for Comfort and Can You Oil Benches?

What to pick for your use

Questions

Can I use a regular couch cushion in a sauna?

No. Regular cushions are not designed for high heat or humidity and may melt, off-gas, or become a fire hazard. Use only products explicitly rated for sauna use.

How do I clean a bench cushion after a sauna?

Check the care label. Most cushions with removable covers should be washed in hot water, while the cushion itself may need to be wiped with a mild soap solution and left to dry completely.

Does a towel protect the wood as well as a cushion?

A towel can protect the wood if it stays dry and is removed after each session. A cushion that traps moisture against the bench can be worse for the wood. Airflow is key.

Can I leave a towel on the bench between sessions?

No. A damp towel left on the bench can cause moisture damage to the wood. Always remove it and allow the bench to air out.

Are there cushions that also help with back support?

Yes, some sauna cushions have extra lumbar support, but they still need to meet heat and moisture requirements. Look for designs that are marketed specifically for sauna or steam rooms.
