My husband has fallen out of bed 3 times. Last time he injured himself. I went on a search for something to prevent him from falling out. Didn’t like the metal and fabric semi ride rails. Too hospital like. A metal side rail is too much. Found this ad. I order the one with the bamboo cover. As bamboo sheets and fabric are cooling. The bumper is a little longer than needed. Would have preferred about 6 -8 inches shorted. The key to having it secure and not move is place it under your fitted mattress pad and then under a fitted sheet. Also place the extra material that is attached to the bumper pad on the mattress pad. The persons weight and being under a fitted mattress pad and fitted sheet made this bumper pad very secure. My husband was able to get in and out of bed easily. The bumper is firm but not hard. My husband stated he slept better than he had in years. As he felt secure. He also didn’t move as much as he usually does. Another Benefit of the bumper pad it feels great against your back. I am a RN and in the hospital setting many times for support and sleeping comport an extra pillow is rolled and tucked up against the patient’s back if they are wanting to sleep on their side or have problems moving. Rolled up pillows are often used to give extra support to the patient’s back. This bumper pad provides the same support. Another nice feature if you read or watch tv before sleeping it allows one arm to rest on the pad.
