Basic Statistics for Epidemiology: Prevalence vs Incidence. In short, epidemiology is sort of the who what, when, why, how and where of disease. It doesnât involve any experimentation or clinical trials, so it is really of interest to public health, because it is just about what happens.
So if a queen-sized waterbed with a bladder-type mattress holds roughly 130 gallons of water that weighs in at 1,084 pounds plus the weight of the frame and two people.o keep the math simple let s assume that the mattress, frame and two adults weighs 1,300 pounds and that the bed assembly measures six feet by six feet taking up a total of 36 square feet of floor space. If we divide the weight of the bed by 36 the square footage-that gets us to 36 pounds per square foot.
My opinion is this, if your house canât handle the weight of a waterbed, then you should probably keep an eye out on your refrigerator and a few other house hold items, they may be just as likely to surprise the people living under you.ince these waterbeds are so lightweight they allow individuals additional piece of mind that they can own one without fear. Waterbeds are a great way to relax and enjoy a great night of sleep. However, many people are afraid that their floor is unable to withstand the weight.
