Sleep / Sleep Analyzer can be used with all brands of mattresses. It is compatible with a wide variety of mattresses including spring, latex, foam, and memory foam. You can place the Sleep / Sleep Analyzer sensor directly under the mattress (between the mattress and the bed platform or box spring). Sleep / Sleep Analyzer can also be used with a slatted frame. In this case, you may need to place a flat, sturdy object (like a cardboard, for example) between the frame and the sensor.
You can also place Sleep / Sleep Analyzer between your mattress and mattress topper or pad. If you feel the device when lying in your bed, you can place it between the mattress and the bed frame.
Note that Sleep / Sleep Analyzer has been tested with a mattress thickness of 4 to 15 inches (10 to 40 cm). However, the sensor has not been tested with, and is not recommended for use with waterbeds and airbeds.
