it is what you are used to and you have no issues getting a full night’s sleep on the bed.
get into the lying position slowly and carefully. sit on the bed, closer to the head of the bed than the foot of the bed. move your body as far on to the bed as you can. then, lower yourself down onto one side using your hands as support. bend your knees slightly and pull them up onto the bed. think of yourself as a rolling log, rolling on your side or on your back.
have your pillows ready on your bed so you can position them easily once you lie down.
