- The Babysense 7 Movement Monitor will work with most standard baby mattresses. The only exclusion is a memory foam mattress – Breathing Movement Monitors will not work properly with this type of mattress.
- If the mattress cannot be in contact with the sensors pads, or if the bed base is soft, padded or contains springs, place extra plywood on the bed base, place the sensor pads on the plywood and press the mattress down firmly on top.
