I'm forwarding this for David Chesler since he does not have access to inews. From genrad!wjh12!unixvax:chesler_2 Sun Jan 15 06:08:31 1984 Status: R I used a mattress-pad on my waterbed. (A letter I wrote to someone else explained why I don't use mine now.) Without some sort of padding it feels awefully clammy (but I have slept on the bare vinyl, in just my briefs, on at least one ocassion, and survived.) In the summer I turn off the heater, and I find an 80 degree bed sucks just the right amount of heat away that I can sleep comfortably. In the winter I keep the bed warm. If it is too hot I can't get up, but if it is warm it is like an electric blanket, but better, especially in a cold room. I don't pay for electricity, but I think a waterbed heater is on the range of 200w, a larger lightbulb, or a miniscule space heater. Even if on continuously I think this is less than $100/yr absolute maximum [redundant stress because of all the liberal figures I've used in the estimate]. The heater won't be on, a comforter over the bed will hold much of the heat in. It must be more economical to heat the bed than the whole room or house. Water holds a lot of heat, but once it is warmed up it doesn't need much input. In case this is posted: Advise: It is easier to heat a bed than cool it. Fill with water, let it warm to room temperature, then raise the heater and increase setting slowly (one bit a night) until the temperature is right. Query: Someone warned against gel filled beds. I assume gel equals very flexible solid. Has anyone done anything with very viscous fluids? (EG SAE 90 grease, vaseline, etc [Would it have to not lose its viscousity at high temperatures? :-)]. I got used to the waves, but when I had guests they did not like them, and neither of us liked the non-resistance water offers. I would like to hear more about soft-sides and the beds which are a standard mattress with a water-filled cavity, as the wooden sides were my worst drawback.

Having just purchased a waterbed a few weeks ago, I thought I'd throw out another comment or two. It is possible to buy waveless or semi-waveless matresses. These use some form of baffle chamber or fiber fill to disrupt and stop waves. I have a 75% waveless mattress, and it damps even the most violent waves to nothing in less than 10 seconds. That way, you get some of the movement, but not enough to disturb someone who doesn't appreciate the waves. Some of the baffle chamber matresses are actually two matresses in one, and this allows you to set the heat and firmness on each side to individual preference. My super fancy deluxe heater is 400 watts for a king size bed, and I'd say it is on less than half the time with the room temperature at about 70 and the bed at about 86. The king size mattress on my bed states that the most it can ever be filled would cause 42 lbs per square foot. Thus, a king size matress fully filled is under 1600 lbs. Imagine 10 people standing in your bedroom at that point -- would the floor hold it? It better, or it doesn't meet with most recent building codes. I don't allow wombats to use my waterbed, although Waldo the Wonder Duck (our cat) is allowed to nap on the bed if the comforter is in place. -- Off the Wall of Gene Spafford The Clouds Project, School of ICS, Georgia Tech, Atlanta GA 30332 CSNet: Spaf @ GATech ARPA: Spaf.GATech @ CSNet-Relay uucp: ...!{akgua,allegra,rlgvax,sb1,unmvax,ulysses,ut-sally}!gatech!spaf
