My girls are both very active and the youngest really like jumping on the bed. Well her jumping sometimes scares me because I am afraid she will fall of the bed onto the floor. She also likes climbing on the window beside the bed and on the bed’s headboard. So that is why we have a foam mattress. Not only is it comfortable for me to sleep on, it provides good back support and the youngest really cannot jump enough on it to damage it or to have an accident. I like sleeping on a foam mattress, it does not seem to transfer as much motion as more traditional spring mattresses, I if your partner moves around a lot at night, you are less likely to feel their movement.
