You could try padding Get some large size clothing, stretch pants, girdles & fill with pillows/blankets or beach balls filled with air or water (water fill eventually ruin the ball) The problem with water is it's difficult to hold up all that weight (might have to use 2 or 3 girdles)

I guess you could use a combination of padding and something that can hold water to make the weight realistic. Maybe a partially filled exercise ball? Sounds mad but it would go a bit of the way to help you similate the size and feel. Plus exercise balls can hold alot of water and you don't have to worry too much about them bursting.
