I purchased these for my sauna.I enjoy them. They have a nice curve and keep my body far enough away from the FIR panels. I had to lean forward before or sit between the FIR panels.
these backrests are the perfect size and weight for the JNH Lifestyles MG215HB 2 Person Far Infrared Sauna 7 Carbon Fiber HeatersI recently purchased.
The backrest keeps you from leaning on the heater panels but can be cumbersome depending on the size of your sauna. I have a two-person sauna so it can be a bit much at times.
They do support your lower back while in the sauna, but that's about it. If they were about twice as long, they would keep your upper back and head away from the heating units as well, which would be nice.
just got it, have not tried it yet
Sauna Ergonomic Back Rest (Set 2/2)
Very pleased with the sauna, how easy it was to set up and it looks amazing!
These are a bit small, but then again, they are made for the smaller sauna I bought.
These are light, well designed and well built. Would recommend.
