The best sauna seat cushions

The verdict: buy the Fovege — it is the only cushion here that publishes *two* separate waterproof layers, an inner padding and the outer cover, which is what actually stops sweat reaching the foam, and it publishes its dimensions to a tenth of an inch so you can measure your bench first. Buy the yeesport if you want the thickest fill (3.1 in) and straps that stop the pad migrating. Buy the BALAPET if your cabin is infrared: it is the only listing that states the limitation that matters there — do not let it touch the panels.

Measure the bench, then the cushion

This is the only way this purchase goes wrong. Three of these four publish dimensions, and they are not interchangeable: 43.3 x 15.7 in, 42.1 x 18.1 in and 43 x 16 in. A barrel sauna's bench is narrow and curved; a cube or indoor room is flat and often deeper. Measure the depth of the seat you actually sit on, not the overall platform, and subtract nothing — a cushion that overhangs the front edge tips when you shift your weight. The fourth pick publishes no dimensions at all, which is why it sits last despite being the dearest.

The picks side by side

The infrared-panel warning

Only BALAPET prints it, and it applies to every cushion here: do not put it in direct contact with infrared panels. Many infrared cabins have emitters at calf and bench level, and a foam pad pressed against one is a different proposition from a pad on a cedar plank. If your cabin has bench-level panels, check the clearance before you buy any of these — and if you are not sure, our infrared sauna buying guide covers where the panels usually sit. In a traditional cabin the question does not arise; the bench is just wood.

Who each pick is for

• Fovege — the one to buy by default. Two stated waterproof layers, published dimensions, machine-washable cover. Skip it if your bench is deeper than 15.7 in and you want it fully covered.
• yeesport — bad backs and wide benches. Thickest fill here at 3.1 in, widest at 18.1 in, and the only one with straps. Skip it on a narrow barrel bench, where it will overhang.
• BALAPET — infrared cabins, with care. A fully waterproof cover, shape-retaining inserts, and the honest panel warning. Skip it if your infrared cabin has bench-level emitters.
• IVOSA — the anti-scald framing. Sold on insulation rather than comfort, which is the real problem in a 190 degrees F cabin. Skip it if you need to check bench fit: it publishes neither dimensions nor fill, and three rivals do.

A cushion is not a towel, and both still get washed

Finnish practice is to sit on a small cloth, and that is still the hygienic baseline — a cushion does not replace it, it replaces the *heat* problem. The sensible setup is a cushion for insulation with a sauna towel over it, because the towel is what goes in the wash after every session and the cover is what goes in monthly. Two of these have zippered machine-washable covers; one is low-temperature wash only. None of them should be left damp in a closed cabin, for the same reason the vents stay open afterwards.

What none of them publishes

• A temperature rating. Four for four. These are foam and polyester in a room that runs to 190 degrees F, and nobody states a limit.
• Dimensions, on one of four. The dearest pick is the one you cannot measure against your bench.
• A non-slip backing. Only the yeesport addresses movement, and it does so with straps rather than grip.
• Fill density figures. All three say high-density; none gives a number.
